What changes will occur in your body during pregnancy?
During pregnancy, a woman's body undergoes incredible, miraculous changes. Uterus, respiratory and circulatory system ini what changes are expected in your body during pregnancy Gynecology and Obstetrics Specialist Op.Dr. View Tevfik's Full Profile It explains.
Changes in the uterus
The uterus is an organ that normally weighs 70 mg and has a maximum internal cavity of 10 ml. In a pregnant woman this space reaches an average capacity of 5 liters to accommodate infants and their supplements. Its weight reaches 1100 gr.
The uterus, which was initially very small in the matchbox, reached a large orange size at the 10th gestational week and is still in the pelvis, not overflowing into the abdominal cavity. Until this period, growth develops globally. With the 12th gestational week, the uterus begins to grow longitudinally, in the form of melons. In the 20th week of pregnancy, the upper limit of the uterus reaches the level of the navel. While all these changes in uterine size occur, the ligaments that hold the uterus in place naturally stretch. This strain often causes groin pain in pregnant women.
The upper limit of the uterus rises up to the lower limit of the faith board at 36 weeks of gestation and regresses to the lower level with the lowering of the baby's head in the last month.
Abdominal Anterior Wall
In advanced pregnancy months, itching and pinkish, rose or silvery streaks (cracks) occur on the anterior abdominal wall and breasts due to skin tension. At the end of pregnancy, these lines disappear spontaneously in some pregnant women and remain the same in others.
In early pregnancy, respiratory rate increases by 10% per minute. In the last months of pregnancy, the mother's oxygen consumption increases by 15-20% to meet the increasing needs of the unborn baby. The extra covering of the uterus in the mother's abdominal cavity has a negative effect on the mother's breathing. In order to compensate for all of this, the changes in the cardiovascular system come into play with a 6 cm increase in the number of respirations and around the rib cage.
The circulatory system
During pregnancy, the heart rate (10-15 beats / minute) and minute beat volume increase to meet the needs of the developing baby. So the heart is pumping more blood. In addition, there is an increase in the number of red blood cells and blood volume assigned to carry oxygen. The increase in blood volume continues until 24-36 weeks of gestation. The increased blood volume is about 1200-2500 ml, with an average of 800 ml of blood circulating in the uterus and the baby's partner (placenta). With the effect of hormones secreted by pregnancy, smooth muscle is seen in the vascular wall and as a result, blood pressure of pregnant women tends to decrease in the second trimester.
Increased blood volume during pregnancy meets the needs of the baby, is used to meet the bleeding that will occur during delivery (normal amount of bleeding at birth: 500-700 ml during vaginal delivery, 800-1000ml during cesarean section). Parallel to changes in the circulatory system, blood supply to the skin and mucous membranes increases. Especially during pregnancy, vaginal wall and perineum (genital area) with increased blood supply and water retention in this region connective tissues and muscles cause relaxation and softening. This is part of the preparations for birth.
An increase in oral saliva is observed during pregnancy. The stomach and intestines are displaced by the thrust of the growing uterus. Appendicitis, for example, has abandoned its classic position in the advanced weeks of gestation and is located on the right side above the navel level.
With the effect of increasing hormones due to pregnancy, the emptying time of stomach and intestine contents is prolonged. This causes more water to be absorbed from the intestines and causes constipation. In order to avoid constipation, expectant mothers should make a habit of drinking more water than normal.
The pressure of the uterus on the stomach and the effect of hormones and gastric pharynx, which forms a barrier between the pharynx and the relaxation of the stomach contents into the pharynx are frequently seen. This causes bitter water to come into the mouth and burns behind the sternum.
Liver And Gall Bladder
Although pregnancy causes liver growth during pregnancy in some animals, it does not cause cell change or growth in humans in the liver. However, it may make acceptable changes in liver function tests.
The situation in the gallbladder is different. Smooth white muscles on the gallbladder wall work more slowly with the effect of pregnancy hormone, which causes more bile to accumulate in the gallbladder and later discharge.
As the gestational week progresses, the pressure on the uterine bladder, which grows, causes frequent urination in pregnant women.
