How much breast increases during pregnancy. For what reasons does breast augmentation occur during pregnancy: when does it start to grow? How much will the breasts increase?

Breast formation is a complex five-step process that raises many questions: when does breast growth begin, and what exactly is its catalyst? Why do some girls form mammary glands earlier, while others do later? How to care for growing breasts, when to buy underwear, and what changes are the norm, and what are the reasons to see a doctor?

When breasts start to grow

In girls with African American and Caucasian roots, puberty begins at the age of 6-7 years, and in European and Slavic adolescents - later 2-3 years. Breast formation is one of the first signs of transition into puberty.

The process is associated with the "awakening" of the reproductive system. First, the girl's ovaries are activated and the production of estrogen starts. The hormone causes the connective tissue of the mammary glands to store fat. Milk ducts are formed, nipples and areoles change.

Doctors believe that the optimal age for breast development is 11–12 years. In some girls, puberty begins later, so breasts appear at the age of 13-14, and this is also the norm.

Sometimes mammary glands form at 8-10 years of age. This is due to early puberty. Doctors do not know the exact reason for the premature transition to puberty, but they believe that these girls have a 20% higher risk of developing breast cancer.

At what age does breast growth stop

The mammary glands develop actively from the age of 13 to 14-15. During the period of active growth, the shape and final size of the breast is determined. At the age of 16-18, the mammary glands continue to grow, but very slowly and almost imperceptibly. Breast development stops at about 18–20 years of age.

Breast growth stages

The female breast takes 5-10 years to develop and mature. The girl goes through 5 stages of breast development.

Stage 1

The first stage begins at birth and lasts up to 7-10 years. The chest remains flat and inconspicuous. Areolas resemble small brown spots that are round or oval in shape. The nipples do not protrude above the surface of the skin and practically merge with the areoles.

Stage 2

The second stage begins after the awakening of the ovaries, at the age of 9–12 years. The mammary glands become more prominent and bulging. The areoles increase in size, and the nipples protrude slightly above the breast surface.

In the second stage, the rudiments of the mammary glands appear. The small tubercles are soft but firm. They are composed of connective tissue and adipose tissue. In the second stage, the milk ducts develop. The process is accompanied by mild discomfort and pain.

Stage 3

The third stage coincides with the onset of menstruation at 12-14 years of age. The amount of connective and adipose tissue increases. The chest is rounded, takes on a more pronounced cone-shaped shape and outline. The color of the areola becomes darker and richer, but the contours of the nipples may remain blurred.

In the third stage, thoracic veins form in girls. They can show through the skin, and this is normal. Also, at the third stage, girls sometimes have swelling in the areola area, and the sensitivity of the nipples increases.

Pain and discomfort may worsen. Especially during menstruation when estrogen levels rise.

Stage 4

In the girl's body, after the first menstruation, progesterone begins to be produced. The hormone does not affect the size of the mammary glands, but makes them denser and more elastic. In the fourth stage, the chest is rounded. Areoles and nipples protrude above the surface of the mammary glands. Their contours become clearer and more visible.

In the fourth stage, the skin is stretched due to the active growth of the breasts, which is why some girls develop pink or white lines - the so-called stretch marks. Small streaks are not abnormal and require no intervention. Stretch marks disappear by the age of 18–20, when the girl's hormones return to normal and the development of the mammary glands stops.

Stage 5

The fifth stage begins after puberty, at the age of 17-19. The development of the mammary glands slows down and stops. The chest takes on its final shape and size. The nipples may deepen and become less protruding, and white dots - the Montgomery glands - form on the areoles.

In some girls, small lumps remain in the mammary glands. If they disappear after 2-3 menstrual cycles, then there is no reason for worry. The fifth stage also reduces chest pain. Uncomfortable sensations appear only before menstruation. In girls, stretch marks also disappear, and the connective tissue is gradually replaced by adipose tissue.

Factors affecting the growth of mammary glands

The size of the mammary glands is most often determined by genes. If mom and grandmother have big breasts, then there is a high probability that the girl will also have a size C or even D.

Heredity is one of the main factors, but not the only one. The shape and size of the breasts is also influenced by diet, stress, daily routine, and physical activity.

Diet

Diet and fasting are contraindicated for teenage girls. Severe food restrictions lead to hormonal imbalance. The production of estrogen and progesterone is suppressed, menstruation disappears, the accumulation of adipose tissue and the growth of mammary glands slows down.

Stressful situations

Scientists from the University of Edinburgh have found that stress affects breast size. In stressful situations, the production of progesterone is suppressed and the concentration of estrogen increases. The hormonal balance is disrupted, due to which there are problems with the development and growth of the breasts.

Schedule

Gonadotropin, which is also called growth hormone, is also involved in the formation of the mammary glands. The hormone stimulates the ovaries and makes them produce enough estrogen.

The body produces gonadotropin during sleep. Regular sleep deprivation decreases the concentration of growth hormone, and the development of the mammary glands slows down. Gonadotropin levels also decrease in girls who go to bed after midnight.

The optimal time for rest is 10-11 am. During this period, the pituitary gland is activated, which produces gonadotropin.

Growth hormone only affects breast size during adolescence. The mammary glands and ovaries of an adult woman do not respond to gonadotropin.

Physical exercise

It is good for teenage girls to play sports. Moderate exercise stimulates gonadotropin production, protects against obesity, and lowers levels of cortisol, a stress hormone that inhibits breast growth.

Low weight girls that help gain weight. Cardio is also useful, but no more than 30 minutes a day. Excessive sports activities interfere with the accumulation of fat in the mammary glands, so the breast remains small. On the other hand, physical activity increases the tone of the skin and muscles, makes the breasts firm and taut.

Breast size in adult women

In adult women, the shape and size of the mammary glands can be influenced not only by diet and daily routine, but also by other factors:

  • pregnancy;
  • oral contraceptives;
  • lactation;
  • smoking;
  • drinking alcohol and caffeine;
  • age.

During the period of gestation and feeding of a child, the body produces prolactin. The hormone stimulates milk production and increases breast size. Oral contraceptives have similar properties.

Smoking, on the other hand, impairs blood circulation in the mammary glands, lowers oxygen concentration and leads to early aging of the breast. Alcohol has diuretic properties and removes water from the body, so the skin becomes dry and the mammary glands lose elasticity.

During menopause, the concentration of estrogen decreases, and the connective tissue is replaced by adipose tissue. During menopause, the breast not only sags, but also slightly "dries out", changing its size and shape.

When to buy your first bra

It is worth buying underwear at the third or fourth stage of the development of the mammary glands, that is, at the age of 11-13. For girls whose breasts are not too noticeable, soft tops without underwire or special T-shirts are suitable.

If your breasts are big enough, you can buy a bra with wide straps and thin foam cups, and for sports you can buy a sports top. Underwear does not affect the size of the mammary glands, but protects the skin from stretch marks.

The main task of the girl or her parents is to choose the correct bra size. Too tight and tight underwear will squeeze the skin, cause chest sweating and uncomfortable sensations. Large, loose tops chafe, increase nipple sensitivity and prevent you from exercising properly.

Why does not the breast grow

Breast development is stalled due to heredity, hormonal imbalance and serious medical conditions.

Heredity

Genes determine not only the color of the skin or hair, but also the size of the mammary glands. When the size of the breast reaches the programmed limit, the brain stops the production of hormones responsible for breast development.

Hormonal imbalance

Some girls start puberty later than their peers. A delay of 2-3 years is considered normal. If, after 15, the girl's breasts and pubic hair do not grow, her period does not go, it is worth contacting a doctor.

Lack of menstruation and developmental delays can indicate hormonal imbalances. It is called by:

  • obesity;
  • lack of B vitamins;
  • liver problems and slow metabolism;
  • diet and anorexia;
  • some medications.

The doctor will determine the exact cause of the imbalance, recommend a diet, and, if necessary, select hormone replacement therapy.

Diseases

Breast growth stops with severe arthritis, cancer and growth hormone deficiency. Growth hormone production is impaired by inflammation of the colon, head injuries, infectious diseases, thyroid or adrenal insufficiency, and also due to genetic pathology.

Sometimes breast growth stops due to regular stress, overuse of caffeine and sugar, as well as a lack of proteins, the right fats and an unbalanced diet.

Breast growth myths

Young girls who do not know about the characteristics of their body often become victims of common myths about the growth of mammary glands.

Breast enlargement massage

Massage with herbal oils, special creams or gels does not enlarge the breasts. It improves blood circulation, tones the skin and slows down aging, but not more.

Eating Phytoestrogens Enlarges Breasts

Natural and synthetic hormones increase breasts temporarily. As soon as a girl stops taking COCs or reduces the amount of soy in her diet, her breasts return to their original size.

The chest should be symmetrical

In adolescents, one mammary gland may be larger than the other. This is fine. The chest becomes symmetrical by the age of 16-18. If the asymmetry persists, and one breast differs significantly from the other by 2-3 sizes, the girl is offered plastic surgery.

How to stimulate breast growth

Creams, herbal remedies, and exercise do not stimulate breast growth. There are only a few working methods to speed up breast development:

  1. A balanced diet high in protein, good fats and complex carbohydrates.
  2. Avoiding tea, coffee, chocolate and other products containing caffeine.
  3. Drinking plenty of clean water.
  4. Adequate sleep and moderate physical activity.
  5. Quitting smoking, alcohol and energy drinks.

A healthy lifestyle has a positive effect on the hormonal background of a girl and creates conditions for breast growth, but even the right habits cannot resist genes. If a woman "inherited" small mammary glands from her mother, then she can increase their size only with the help of a plastic surgeon and silicone implants.

After the onset of pregnancy, a woman's body changes greatly. Under the influence of hormones, the breast begins to grow, which makes it possible to prepare it for feeding the baby. How long can a woman notice changes? How much do the mammary glands increase during gestation? What does the absence of pain and breast engorgement signalize?

How does a woman's breast work?

The breast is a paired organ necessary for feeding a child. The mammary glands, as a rule, are not the same - the difference between them in a woman can normally be up to 2 sizes. An organ is made up of several types of tissue:

  • Glandular. It is divided into separate glands and forms the so-called lobules, of which there can be from 30 to 80 pieces. Each small gland consists of microscopic tubes ending in alveoli - in which milk is formed. Some women have additional lobes extending to the armpits, which causes soreness in this area during pregnancy.
  • Fatty. Its amount depends on the characteristics of the organism. If there is a lot of adipose tissue, when a woman's body weight changes, the volume and shape of her breasts changes significantly.
  • Connective. This tissue divides the gland into 15–20 large lobes.


The tubules in the glandular tissue connect and merge at the nipple into the lactiferous ducts. The nipple is surrounded by an areola and is characterized by the presence of a huge number of receptors, the irritation of which stimulates the secretion of milk. In nulliparous women, the areoles are pink; after pregnancy, they darken, becoming brown. In addition, the conical shape of the nipple may change - it takes the form of a cylinder.

What changes occur in the mammary gland during pregnancy?

Dear reader!

This article tells about typical ways of solving your questions, but each case is unique! If you want to know how to solve your particular problem - ask your question. It's fast and free!

Usually, during pregnancy, women notice that the mammary glands are gradually growing and begin to cause discomfort: whine, pull, hurt. The intensive growth of this paired organ is observed in almost everyone, as the body prepares for feeding the child. Due to the enlargement of the glands, a blue or burgundy vascular network appears on the skin. In addition to this, other changes are taking place:

  • Increased sensitivity. Many women complain about this, but if some simply experience discomfort, then most pregnant women note that their chest hurts.
  • The appearance of stretch marks. If the skin is not elastic, stretch marks form when the mammary glands swell. Small breasts do not guarantee the absence of stretch marks - the possibility of their formation is minimized only with a sufficient volume of intradermal collagen.
  • The color and size of the nipples. Areoles darken and become larger, increasing in diameter up to 5 cm. The nipple itself also becomes 2-3 mm larger. Pimples are formed along the contour of the areola.
  • Isolation of colostrum. A woman sometimes begins to notice these changes from the 2nd trimester of pregnancy, but more often colostrum appears from the 5th month or only after childbirth (for more details, see the article :). It is a white or yellow sticky mass that is released in small droplets from the nipples. It is she who is the first food for a child who receives a maximum of nutrients and antibodies with colostrum.

Breast changes during an ectopic pregnancy will be similar. After the completion of lactation, the mammary glands become smaller, the painful sensations disappear.

How long is breast enlargement noticeable?

The glandular tissue grows under the influence of progesterone, and estrogen promotes the expansion of the milk ducts. How long does it take to start these changes? Experts say that the breast changes from the very beginning of pregnancy (more in the article :). The pain appears due to a strong increase in the volume of glandular tissue, which is especially noticeable in the first 2-3 months. It is believed that by 10-12 weeks of pregnancy, the main changes in the mammary glands end - they are already prepared for feeding the baby, so the growth process slows down significantly.

The unpleasant sensations disappear by about 12-14 weeks, when the body gets used to hormonal surges. For some women, chest discomfort disappears by the 5th week, for others, the entire pregnancy continues, and both are normal options.

At the final stage of gestation, prolactin begins to be produced, which is responsible for milk production. Due to this, the alveoli are filled, and the mammary glands continue to enlarge. The breasts are at their maximum size before delivery. The connective tissue that grows during pregnancy is transformed into adipose tissue after the completion of lactation.


Since each organism is different, changes occur in pregnant women in different ways. For example, the breast may not change at all throughout the entire period of gestation, or will begin to grow only at 6-7 months, or swell after childbirth. Most often, the mammary glands do not grow in women who have given birth, but do not worry - this will not affect the quality of the feeding.

How much does the breast increase during pregnancy?

During gestation, the breast increases by 1-3 sizes. Weight gain will be from 150 to 900 g. In each trimester, certain changes occur:

  • 1 trimester. The woman notes an increase in the glands by 1 size. This is due to increased tissue growth and the formation of additional milk ducts. Changes may not be noticeable from the outside, but the pregnant woman feels swelling, increased elasticity and tightness of the skin. In some expectant mothers, breast weight reaches 400-700 g by 3-4 weeks (more details in the article:).
  • 2 trimester. The expansion of the ducts reaches a maximum, the growth of glandular tissue gradually slows down.
  • 3 trimester. Due to the increase in the volume of glandular tissue, the skin is stretched, which leads to itching. Breasts begin to grow again from 31-32 weeks, when colostrum is actively produced, and gains maximum weight by the time of delivery.


Why the mammary gland may not change in size and what does this mean?

Sometimes pregnant women do not notice that their breasts have enlarged. It would seem that the mammary glands should swell, but this does not happen - they remain soft and of the same size. Why is this happening?

This may be due to the characteristics of the body - the glands will begin to swell in the 3rd trimester or before childbirth. However, if there are doubts and a bad feeling, it is better to contact the gynecologist leading the pregnancy. Sometimes the absence of pain and pulling sensations is associated with a dysfunction of the thyroid gland and adrenal glands, which are involved in the secretion of prolactin.

During pregnancy, a woman needs to pay attention to other signs that arise along with the absence of pain and breast growth. You should go to the hospital if you have the following symptoms:

  • stomach ache;
  • general malaise;
  • a sharp increase in temperature;
  • the appearance of bleeding from the vagina;
  • an increase in local temperature when the chest is "on fire";
  • the presence of depressions in the chest, its asymmetric increase;
  • collapse of the mammary glands and their return to their original state.

If a woman develops at least one of the above symptoms, the gynecologist may suspect a threat of miscarriage or a frozen pregnancy. An increase in temperature in the gland can speak of mastopathy - inflammation, in which discharge from it appears and the growth of fibrous tissue is noted.

The body of each woman is individual, but at the slightest pathogen it reacts immediately. This also happens after conception. Definitely, any expectant mother noticed exactly how her body changed when the egg was fertilized, and what happens to the mammary glands during this period.

If you are planning a pregnancy, it is important to know how long after conception the breasts will enlarge. This will help determine fertilization.

It is important for every woman to knowhow long after conception the breast enlarges, because this process is most often accompanied by unpleasant sensations.

During this period, there is a change in the hormonal background in the body. When a sperm is reunited with an egg, the body begins to produce a special hormone - progesterone.

It is a hormone that is responsible for preparing the female body for bearing a baby. In scientific words, progesterone is a steroid hormone of the corpus luteum of the ovary (chemical formula C 21 H 30 O 2).

It is the mammary glands that are the organ that first responds to the emergence of a new life. They are one of the most important parts of the reproductive system in a woman's body, as they produce breast milk for feeding.


Changes in the mammary glands after fertilization and the onset of reproductive processes in a woman's body

When the mammary glands swell, stretch marks appear on the skin of the breast - this is a kind of shock for collagen fibers, which cannot withstand such a sharp load and are torn. The chest changes both outside and inside.

Milky ducts and connective tissues begin to grow, and the skin gradually stretches and swells the entire surface of the breast, red or burgundy stretch marks appear, and its sensitivity increases.

Even the lightest touch can cause an unpleasant, sharp feeling of pain and discomfort.

How long after conception does the breast enlarge?

Pay attention to how long after conception the breast enlarges. According to doctors, this happens in about 2-3 weeks.

However, sometimes even after the 6th week, nothing is noticeable, since the hormonal background, the state of the immune system and the genetic characteristics of the body of each woman are different.

It increases in volume, and this, in turn, causes discomfort, and in some cases pain. The breast enlarges for the first 11 weeks, then it slows down, and immediately before childbirth begins to swell again intensively.

During the entire process of carrying a baby, the breast becomes lush and raised. The body makes it clear to the woman that she will soon become a mother, and is completely rebuilt for the favorable development and growth of the child.

When does the chest start to hurt and why does it hurt? How long does breast hurt during pregnancy?

Some time after conception, the entire female body works to achieve only one single goal - bearing a child. Almost on days 5-10, a woman may notice small changes in her breasts. A large flow of blood begins to the mammary glands of the expectant mother.

Moreover, a vein may appear, the skin stretches, and the soft fatty tissue inside the breast enlarges- grow. All this leads to unpleasant, and even sharp pain. Only a few women have this process painlessly.

If a woman decides to have a child, she must understand that the body will change dramatically and the entire pregnancy can pass with rather unpleasant sensations.


Chest pain usually goes away by 13 weeks of gestation, but there are also such cases that the cuts of the mammary glands stop only before childbirth. In addition, the expectant mother must be ready for the discharge of colostrum from the breast, for this you will need special underwear and water-absorbing pads.

How to relieve chest pain

The most the main requirement for reducing painful sensations is comfortable underwear... In no case should you use a tight-fitting bra. The underwear should be seamless and on wide straps so as not to cause inconvenience to the woman's sensitive organ.

There can be no question of synthetic fabric or jewelry on underwear. Any bead can hurt and squeeze or chafe delicate skin. It is best to start using a special maternity bra. You can try sleeping in it so that you do not experience pain at night while sleeping.


Doctors advise taking care of the breasts during pregnancy, including wearing special supportive underwear that is most comfortable.
  • wipe the breast with a damp and soft towel several times a day;
  • do not use soap or shower gel (they can dry out the skin of the breast);
  • with severe pain, it is necessary to postpone sports;
  • no need to squeeze or rub your nipples;
  • a contrast shower is required.

Why does the breast suddenly stop hurting during pregnancy?

After a while, the chest pain disappears, but you shouldn't worry about it. Both the child and the mother are all right, just some women have pain at the beginning and at the end of pregnancy.

Having increased after conception, she finally bounces back and slows down her growth a little.


Doctors pay attention to the need for massage, physical activity (you can attend special courses for pregnant women), walks in the fresh air, proper nutrition and eliminate all stress from life.

When the chest suddenly stops hurting, you should not panic, there is no threat to the development of the child.

Other early signs of early pregnancy

As you know, breast augmentation after conception is not the only sign of pregnancy. There are several more factors that will help to understand whether the fertilization of the egg has occurred or not. For instance:

Signs of pregnancy Description
Delayed menstruation A delay in the menstrual cycle is one of the main factors in pregnancy. After all, if the egg is fertilized, then others stop being produced. But, it is important to know that a delay is not always a sign of pregnancy. Only a doctor can confirm conception.
Nausea (toxicosis) Nausea happens not only in the morning, there are women who are tormented by it 24 hours a day for all 9 months, but fortunately there are very few of them.

Toxicosis is a mystery of the female body. Scientists around the world still cannot say with 100% certainty what it is connected with, where it comes from and why it disappears. But toxicosis should not always be perceived as nausea. It is also a change in a woman's tastes and preferences., complete aversion to food, or vice versa, excessive appetite.
Lower abdominal pain Sometimes, after conception, a woman may feel an unpleasant aching pain in the lower abdomen. This condition is similar to pain during menstruation. But don't worry.

This is because the fertilized egg attaches to the wall of the uterus and the woman may feel muscle spasms... It is important to know that if the pain is very severe and does not stop, it is necessary to urgently consult a doctor.
Dizziness Dizziness may be due to stress on a woman's organs, such as the heart or blood vessels..

Some people observe an increase or decrease in pressure - these are also the reasons for this unpleasant factor.
Sleepiness and tiredness

The body prepares for major changes, thus, it forces the expectant mother to maintain strength and rest more.

Pregnancy is a wonderful time for every woman, given by nature. Yes, it doesn’t feel very pleasant, but it’s worth it. Indeed, after some 9 months, a lump of happiness will appear, which will make you forget about all the inconveniences, pains and poor health of a woman. Take care of yourself and be healthy!

From the moment of fertilization, global changes take place in the mother's body. Some of them we cannot see and feel, others - on the contrary, are noticeable to you and others.

Breast at the beginning of pregnancy

Breast during pregnancy just signals us about a new life that has begun. Many have breast swelling and tenderness. Slight breast enlargement can be observed already in early pregnancy. In the later stages, there is a significant increase in the breast.

But do not forget about the individuality of every woman.- Someone will experience significant changes (the breast will greatly increase in size, it will be painful), while others will remain the same. And this is not a pathology. Moreover, everything depends not only on the characteristics of the woman, but also on the pregnancy itself: for example, in the first pregnancy there will be changes in the breast, and in the second not.

So, the most important thing that we found out - the individual nature of changes in breastfeeding during pregnancy. Now is the time to understand what exactly might be happening?

Breast during pregnancy: questions of pregnant women

Pregnant women are often worried about questions about breasts: its size, discharge, care. How to properly prepare your breasts for breastfeeding? How to maintain firmness?

Every woman should know everything about her breasts and observe her condition throughout her life. Therefore, let's start with anatomy.

Female Breast Anatomy

The breast is a paired hormone-dependent organ that is part of the reproductive system and produces milk. A woman's breast has a complex structure and consists of:

  • glandular tissue (parenchyma), with ducts of various diameters passing through it;
  • stroma (connective tissue);
  • adipose tissue, in which the parenchyma and stroma are immersed.

Breast shape and size depends on the ratio of these components. But neither the size nor the shape of the breast affects a woman's ability to breastfeed. I know many women with large and small breasts who have not had any problems with breastfeeding.

Each type of breast tissue does a specific job: the parenchyma produces colostrum and then milk, the stroma divides the breast into lobes and lobules, and determines the shape of the breast, and adipose tissue plays a protective role and also affects the shape of the breast.

Parenchyma of each breast consists of many alveoli - small tubular glands that can produce milk. 150-200 alveoli are combined into a lobule, and 30-80 lobules - into a lobe of the mammary gland.

Each breast has 15-20 lobes(sometimes there are additional lobes, usually located in the armpits, which is why some women have armpit swelling during pregnancy).

From each alveolus there is a milky duct, the milk ducts are combined into large ones, which flow into the nipple. The lobar ducts expand towards the edge of the nipple and form a kind of cavity - the lactiferous sinuses, in which milk accumulates.

The chest is attached to the muscles of the chest with connective tissue cords, called Cooper ligaments.

It should be noted that the chest does not have muscle tissue, so it cannot be pumped up with strength exercises.

Near the breast: under it, above the collarbone and in the armpit there are 30-40 lymph nodes that perform a protective function against the spread of microbes.

Woman breast: nipples

The nipple and areola are covered with delicate skin. Each woman has a different shape and size of the nipple. The nipple is tapered in nulliparous women, cylindrical in women who have given birth. About 4% of women have flat and inverted nipples, but this shape does not interfere with breastfeeding.

In the female breast (in the nipples and areolas) there is a huge number of nerve endings - this is one of the most sensitive erogenous zones of the female body. The areoles contain Montgomery glands that form small elevations around the nipple.

There are holes on the surface of the nipple- Milky pores, which are the end of the milk ducts.

Breast during pregnancy: hormones and preparation for lactation

Pregnancy is followed by childbirth - the birth of a baby, which means that the breast must "prepare" for lactation even during pregnancy.

All metamorphoses with the breast during pregnancy are associated with changes in the levels of sex hormones: 15 hormones and hormone-like substances affect the breast.

Estrogens affect the growth and size of the breasts, as well as the development of ducts and connective tissue.

Progesterone in large quantities produced during pregnancy, responsible for the growth and development of the parenchyma: an increase in the number of alveoli, lobules.

Prolactin- hormone of active stimulation of lactation: leads to the growth of cells that produce milk.

Chorionic gonadotropin protects breast tissue from breast cancer.

Thyroid hormones affect the secretion of prolactin.

Adrenal hormones enhance the effect of prolactin on breast tissue.

Oxytocin "feeds" milk into the ducts.

What Happens to Breasts During Pregnancy?

Breast growth and change during pregnancy occurs under complex hormonal influences.

Increase in breast size during pregnancy

The process of their increase occurs due to the growth of glandular tissue. An initial 10-week period is noted in which rapid breast growth occurs due to an increase in the number of alveoli, lobes and ducts.

Changes in the breast continue until the very birth and the beginning of lactation. Each breast can increase in size from 150-200 g to 300-900 g. This change occurs already in the first month of pregnancy (in the first trimester).

If the breasts did not swell during pregnancy, then this can be expected after the birth of the baby.

It also happens that breast size does not change during pregnancy and the postpartum period: but this does not interfere with successful breastfeeding. More often, the breast does not increase in multiparous.

Breast tenderness and tenderness

Manifestation of blue streaks (not stretch marks!) - blood vessels caused by increased circulation.

A thick, yellowish discharge from the nipple (colostrum)

From the second trimester (for some in the middle of pregnancy, and for some only after childbirth), the breast of a pregnant woman begins to secrete colostrum, which in the future "turns" into milk.

Changes in nipples and areolas

Darkening of the nipples and areolas, an increase in the diameter of the areolas from 35 to 51 mm, the nipple itself - from 10 to 12 mm. Changes in the color of the nipples are associated with the activity of melanocytes - skin cells that produce pigment. The role of color changes in pregnancy is poorly understood. However, there is a version that the dark areola is a visual signal for the newborn.

Swelling of the glands on the surface of the areolas - Montgomery tubercles

Stretch marks on the chest during pregnancy

Breast skin during pregnancy refers to areas of risk for the occurrence of stretch marks, which is certainly associated with an increase in its size. Stretch marks on the chest can appear during the period of the most intense increase in volume.

The presence or absence of stretch marks depends on the structure of the connective tissue - the ratio of collagen and elastin, "responsible" for the extensibility and elasticity of the skin.

Stretch marks are where connective tissue breaks. When they appear, they have a red color, and over time they brighten and practically do not differ in color from the skin of the breast, but the skin in these is thinner.

Breast care during pregnancy

Breasts during pregnancy require care. A good and comfortable bust is necessary to maintain the shape. Remember that it should support, but not squeeze, your breasts. The bust should be made of natural fabrics (microfiber, lycra, elastane, tactel are also suitable) and fit perfectly.

Breasts during pregnancy - all focus on the nipples!

Particular attention should be paid to the nipples. Some women have flat or inverted nipples, but they develop during pregnancy and breastfeeding.

You can examine your nipples: if the nipple is pulled out with difficulty, then it is poorly stretched. If the nipple does not extend, but goes deeper, it is retracted. If the nipples are inverted or flat, then a special massage should be done from 36 weeks of gestation.

Is it possible to maintain the shape of the breast if you stop breastfeeding?

Nature cannot be deceived - changes occur already during pregnancy: connective tissue grows long before the baby is born.

And if there is no pregnancy?

Breast enlargement and soreness can be the cause of mastopathy, to mark the onset of the menstrual cycle, be a sign of an inflammatory process. Therefore, if you are not pregnant, then consult a mammologist.

Often, women notice some changes in their bodies even before the test. One of the first "bells" - the breast during pregnancy, which swells, hurts or becomes too sensitive. Someone attributes this to premenstrual syndrome, while in fact the life of the unborn baby begins to develop.

Rapid hormonal changes quickly make themselves felt, therefore, even at the beginning of pregnancy, the female breast undergoes the first changes. It is important to understand which condition is considered normal and which should be feared.

How breasts change during pregnancy

Usually, the breast of a pregnant woman increases in size and painful sensations appear. Increased sensitivity is noted. The color of the halos and nipples changes. Often, because the breast swells, the vascular network appears.

With an ectopic pregnancy, there are the same changes in the breast as in a normal pregnancy.

Due to the fact that the mammary glands are enlarged, they appear. Rapid growth is noted in the first trimester, and then closer to childbirth. The breasts can increase by several sizes. If the skin is not elastic enough, the appearance of stretch marks cannot be avoided.

But nowadays this is not a problem - there are many safe and oils that can be used.

Norm

Each person is different. Therefore, you should not think that during pregnancy, everyone's breasts "behave" in the same way. The period when the changes begin is also different for everyone. In some expectant mothers, already at 11 weeks, the mammary glands look the same as in others only during lactation.

Expectant mothers wonder if one breast can hurt during pregnancy. Doctors answer that such a phenomenon is not a cause for concern.

Major changes

Increase ... The intensive growth of the mammary glands is what happens in everyone, since the body prepares for motherhood, feeding. Already in the first month, women clearly notice how the breasts swell during pregnancy.

If there was a rapid growth even during the gestation period, then after childbirth nothing will change or only slightly. Do not worry if the breast does not increase during pregnancy - sometimes the process begins only by the sixth or seventh month.

Estrogens stimulate the proliferation of the milk ducts, and the glandular tissue grows due to progesterone. Connective tissue also grows, and after the end of feeding, it is converted into adipose tissue.

Hypersensitivity. Women report that they experience unpleasant sensations. Someone just has hypersensitivity, and the bulk notes that during pregnancy, the chest hurts. She pours and becomes tense. This always speaks of active preparation for breastfeeding and is the first sign of an interesting situation. Sometimes such sensations arise even before the delay in menstruation.

Changing the nipples. The first signs of pregnancy are not just an increase in size. The nipples change in color and shape. They become larger, and pimples appear around them. The area near the nipple and he himself darkens. Blood vessels begin to appear. After childbirth, these manifestations disappear.

Isolation of colostrum. The appearance of a thick, sticky yellow mass from the breast in pregnant women is a necessary stage before the appearance of milk. Colostrum contains even more vitamins and antibodies than milk. This is the first food from which the baby will receive the most useful substances.

Stretch marks. Even if the breasts are small, this does not mean that stretch marks will not be guaranteed. It can increase by several sizes, which will certainly entail striae. It's not about the volume of the breasts, but about the elasticity of the skin. If enough collagen is present, there is little risk of stretch marks.

Some note that the breast is covered with dark purple stripes after pregnancy - this is a consequence of damage to the blood vessels. With proper care, you can avoid the appearance of bright stretch marks and quickly return your breasts to their normal appearance. It is important to start even before the woman feels that her skin itches.

What is considered a dangerous signal?

Usually, women begin to panic when, over time, the breast does not increase during pregnancy, it remains soft to the touch. This does not always mean that it is worth raising the alarm, but the expectant mother needs to listen to her body and other dangerous symptoms.

When registering, ideally at week 9, you need to listen to your feelings and tell your doctor about them.

Causes for concern:

  • appearance;
  • the appearance of blood from the vagina;
  • asymmetric breast enlargement, the presence of depressions or swelling;
  • a sharp rise in temperature;
  • general malaise.

If one or more of the listed symptoms appear, an urgent need to consult a doctor. You need to carefully consider your body if the breast has fallen out and returned to its previous size. It so happens that the mammary gland decreased even at 8 weeks - in the midst of preparing the body for lactation.

In the event that the chest does not hurt during pregnancy, the gynecologist may raise the question of a frozen pregnancy or vol. It happens that the chest "burns". Perhaps this is a manifestation of mastopathy - inflammation of the breast, in which fibrous changes and discharge occur. If at least one - left or right - breast becomes hot, it is necessary to see a gynecologist.

How long does it take to change and how long does it last?

Expectant mothers are interested not only in what kind of breast becomes during pregnancy, but also for how long it will stop changing. It is impossible to answer this question unequivocally. A woman's body can respond to the release of hormones in different ways. Some have noticed that the breast hurts during pregnancy throughout the entire period. And this is a variant of the norm.

Other women say that the breasts did not show themselves in the first weeks of pregnancy, and during the entire period of gestation. But this does not mean that the body is malfunctioning.

Is it normal if a woman does not feel when her breasts hurt during pregnancy? Perhaps it initially has more room for the growth of glandular tissue. Therefore, the growth did not become so pronounced. Often women note that the most unpleasant sensations occur in the early stages and all symptoms disappear by 14 weeks. The tissues adapt to the surges in hormone levels and it becomes lighter.

Experts note that in most cases, already at 10 weeks, the moment comes when a significant part of the changes in the breast has occurred. This does not mean that the process is complete, it just gradually declines. Do not worry if your breasts stop hurting during pregnancy at about 12 weeks. Most likely, the time has come when the body has completed the first stage of preparation for the birth of a child.

It is important that the expectant mother remembers her individuality, and does not listen to pregnant or giving birth girlfriends. You should not compare and look for "alarm signals" in yourself. It is wrong to ask friends when the chest stops hurting during pregnancy, because there will be no single answer. Someone already at 5 weeks recedes the first signs of preparing the mammary glands for feeding.

The expectant mother may stop suffering from breast soreness at 7 weeks or much later - all these are normal options. However, if you are tormented by suspicions, it is better to consult a doctor and not worry in vain.
