To ensure that the process of intrauterine development has not been disturbed and passed along the line drawn, all the systems of the future mother begin to work with a double load, since the fetus needs to create favorable conditions for development, provide nutrition and oxygen. But changes occur not only with a tiny organism, but with his mother. Let's see what changes in the girls during pregnancy.
Toxicosis.
On the second - the third week of pregnancy, when it is considered to have come, and the fetal egg is fixed in the uterine cavity, the mother's body produces hormones that protect against miscarriage. At this stage, the hormonal background of the pregnant woman changes dramatically, which leads to morning sickness, frequent changes in mood, depression, and capriciousness. Scientists have found that toxicosis is a sign that you will be able to endure the baby without problems, and the birth will be successful. Despite the fact that such a discovery is certainly positive, many pregnant girls, sometimes can not even go out for a long time from home, as they are constantly tormented by nausea. But the toxicosis is not eternal and by the third month the hormones in the body normalize their activity.
The weight.
One of the most noticeable manifestations of pregnancy is weight gain, but do not panic, as this is a physiological process that ensures the normal development of your child. For the entire period of pregnancy a woman types about 10-13 kg of weight, of which 4-4.5 kg is the weight of the fetus, amniotic fluid, placenta, amniotic membranes, 1-1,5 this is the mass of the uterus and breast, 1.5 kg of blood , 1 kg of intercellular fluid and plus an increase in the fat mass of the mother - 4 kg, which provides the baby with the future milk. It should be noted that the smoking and drinking girls weight is much worse, and babies are born small and with reduced immunity. So, that future mothers, it is worth considering your way of life.
Breath.
A small body inside the mother's body needs oxygen every second, so the pregnant girl's concentration increases as hormone progesterone, responsible for the additional relaxation of the muscles of the walls of the bronchi and increase the airway clearance. All this contributes to an increase in the amount of air breathed by the mother by 40%, of which 30% is consumed by the fetus itself, and the remaining 10% is consumed by the systems of the organism of the most pregnant woman.
Heart and blood vessels.
The main load during pregnancy falls on the cardiovascular system, because through rapid heartbeat, left ventricular hypertrophy and an increase in the minute volume, all the necessary substances are delivered to the uterus. In addition to accelerating the heartbeat, the pregnancy increases the blood volume by almost one and a half times, in connection with this, often in girls in the situation there is an increased vascular tone. Arterial pressure in the first 18 weeks is slightly reduced, because of what a pregnant woman can feel weak and lethargic. And by the middle of the second trimester, a pressure increase of 10 mm is observed. gt; Art. After delivery, the situation with the pressure is normalized. But it is very important to monitor the pressure during the period of gestation, since high leaps can provoke miscarriage or premature birth.
Blood.
Pregnancy requires the maximum efficiency from the maternal organism, so it is not surprising that a woman has hemopoiesis, a number of erythrocytes, hemoglobin and plasma. By the end of pregnancy, the total amount of blood increases by 40%. With physiological pregnancy, there is a change in blood composition, changes in its acid-base balance. If the buffer systems are pregnant in normal and have sufficient capacity, then there is no special displacement of PH.
Bone and muscular system.
During the entire period of pregnancy the body prepares for childbirth and produces a hormone like relaxin, responsible for the safe divergence of pelvic joints and muscles for successful passage of the fetus. In this regard, in the last trimester, a pregnant woman can feel an increase in mobility in the joints, sometimes there are rheumatic pains in the hands, knees and elbows. Everything is normalized right after delivery.
Leather.
The skin of a pregnant woman can also be tested, with which amazing changes occur. By the middle of the second trimester, a woman can observe the appearance on the face of a large number of freckles, the line from the navel to the pubis darkens, and becomes dark brown, and darken the nipples. Such changes are due to the fact that the adrenal glands produce a pigment similar to melanin. The closer the term of birth, the greater the uterus, which leads to a stronger stretching of the skin in the abdomen and back. If the skin of a pregnant woman has a good supply of protein such as elastin, the striae that arise during pregnancy will quickly disappear after childbirth. If the protein is not enough then, unfortunately, stretch marks will be clearly visible throughout life.
Selection system.
One of the unpleasant moments of pregnancy is dependence on the toilet. By the second trimester the uterus is already sufficiently enlarged and puts pressure on the bladder of a pregnant woman. The longer the period, the more pressure that provokes frequent urination. Since the kidneys can not process all the liquid in the body of a future mother, many women suffer from swelling. In such cases, it is necessary to normalize the level of consumed liquid per day and exclude diuretics and preparations.
Food.
Each pregnant girl has a change in taste preferences. Often, what she liked before pregnancy at this point is disgusted with her, and she chooses those foods that she did not eat before. But you should pay attention to the fact that there is a pregnant woman, because her food plays the most important role in the formation of the baby. From the diet it is necessary to exclude too fatty food, spicy spices, all kinds of snacks and sweets. In its diet should be fruits, berries, meat, dairy products, vegetables, greens and legumes!
So, as you can see, what changes in the girls during pregnancy. The organism of a pregnant woman is subjected to heavy loads and changes, but still it remains a woman beloved, desired and beautiful.
