To understand what changes occur in the body of a pregnant woman, it is necessary to decompose them into points and consider each separately. - body weight and metabolism. During the entire pregnancy, a woman adds weight by 8-18 kg. Do not be afraid of this figure, because all the weight is distributed according to the following principle: Fruit, amniotic oxen, placental shells - from 4 to 4, 5 kg. Uterus-the weight of the uterus increases from 50-100 grams to 1 kg. Blood – during gestation, about 1 liter of blood is added to the body of a pregnant woman. Adipose tissue and tissue fluid - about 5 kg.
Help! In the first half of pregnancy, the weight increases by about 4 kg, in the second-2 times more. The woman's metabolism is adjusted to take into account the fact that another small person is growing and living in the womb. The production of digestive enzymes is doubled. A woman should make a menu so that together with food, her body receives a sufficient amount of nutrients, vitamins and trace elements. - nervous system the first 4 months of pregnancy are accompanied by inhibition of the nervous system. In most cases, the expectant mother becomes lethargic, sleepy and apathetic. Thus, her body creates all the conditions for the fetal egg to become fixed, and the embryo began to develop. After 4 months, the situation changes dramatically: there are sharp changes in mood, the reaction to mental and physical stimuli becomes more acute. In some cases, there are neuralgic pain in the lower back. - respiratory organs in the last term, the growing uterus shifts the diaphragm up, however, this does not affect the volume of inhaled and exhaled air. The breathing rate remains the same. Physiological changes are minimal. - cardiovascular system, blood pressure in contrast to the respiratory system, the cardiovascular system is experiencing significant changes: More on the topic how does the smell of a woman change during pregnancy? Physiological and psychological changes during pregnancy at what time does the belly become visible during pregnancy? What happens if you are nervous during pregnancy? The uterus during pregnancy Increases the volume of circulating blood: at about 32 weeks, it becomes 35% more than before pregnancy. This corresponds to the increased requirements of the uterus and fetus, protects against hypotension syndrome in the supine position and critical blood loss during childbirth. Changing the composition of the blood. The number of red blood cells decreases slightly, the level of folic acid in the plasma decreases, the concentration of hemoglobin and the value of hematocrit decreases. This increases the number of white blood cells, the rate of settling of red blood cells and the concentration of fibrinogen. Blood pressure changes. In the first half of pregnancy, blood pressure decreases, and in the second, on the contrary, it increases. It is important to make sure that pressure surges are not accompanied by a sharp deterioration in health. The venous pressure
in the legs increases, and there is also compression of the Central nerve trunks. This can cause varicose veins, severe swelling of the extremities, and in some cases even hemorrhoids. - digestive organs and secretions Changes in the digestive tract many expectant mothers notice with the first signs of toxicosis – increased salivation, susceptibility to odors, nausea and vomiting. There are unusual food cravings or aversions to familiar dishes. In addition to the obvious: the metabolism accelerates; the liver begins to work in an enhanced mode, providing dehydration of decay products; there is a tendency to constipation or diarrhea, due to the fact that the growing uterus presses on the intestines. - urinary organs the Urinary system works for two, which is why the expectant mother is forced to visit the ladies ' room twice as often. In addition, as the uterus grows, it puts more pressure on the bladder, which also leads to frequent urination. Help! During pregnancy, the tone of the muscle layers of the urinary organs is significantly reduced. - endocrine system the Endocrine system is a kind of 'conductor' of the reproductive function. Normal functioning of the hypothalamus, pituitary and ovaries ensures the development of the egg and contributes to successful conception, and hormones produced by the endocrine gland are responsible for the formation of bone tissue and the brain of the embryo. Changes in the functioning of the body of the future mother are caused by the influence of the endocrine glands. The ovaries are slightly enlarged, and one of them up to 4 months contains a functioning yellow body. Then, the placenta takes over the production of progesterone and estrogens. Gradually increases the number of blood vessels that expand and encircle the uterus. - skin, hair and nails No matter how much the future mother would like to look perfect while carrying a child, this is not always possible due to natural physiological changes. Due to a hormonal surge, the skin on the face can become more oily and covered with small pimples, as a rule, this is a normal and reversible process. Help! There is a sign that damage to the skin on the face and deterioration of hair is a sign of bearing a girl. It's not just the face that gets hit – the chest and stomach can be covered in brown pigmented spots. The reason for this is a change in the activity of the adrenal glands. If the skin is not elastic enough, stretch marks appear on the stomach and thighs. As for hair and nails, their condition is strongly influenced by the level of calcium in the body. As already mentioned earlier - its deficit becomes especially noticeable in the fifth month of pregnancy. Hair may start to fall out, split, and nails may break and flake. The situation can be corrected by adding calcium-containing foods and vitamin and mineral complexes to the diet. It is noteworthy that the loss of hair on the head can be accompanied by hair loss in completely unexpected places: the chin, tailbone, 'path' from the navel to the groin, and so on. - the immune system for clarity, we can imagine that the body of a pregnant woman works in a mode of saving resources, so that its reserves are enough to ensure the life of both the mother and the embryo growing in her womb. Specific
(acquired immunity) significantly decreases, while non-specific, on the contrary, increases. This process can be tracked by the composition of blood cells and plasma proteins. Important! It is twice as easy for a pregnant woman to catch a disease transmitted by airborne droplets. Therefore, before going out in the cold season, wear a medical mask.
