During pregnancy, your body undergoes many changes. Pregnancy is the term used to describe the period when a fetus develops inside a woman’s womb. The pregnancy process covers about 40 weeks from the last period to the birth of the baby.
Medically, pregnancy follow-up is done by separating it into three pregnancy sections called trimester. So each trimester consists approximately three months of time.
During normal pregnancy, very pronounced anatomical and functional changes occur in each organ system of the mother. The majority of these changes begin immediately after fertilization in response to physiological stimuli from the fetus and placenta and continue during pregnancy.
The uterus, called ‘Uterus’ in medical language, is normally 60-70 grams. The volume is approximately 10 ml. Starting to grow gradually from the beginning of pregnancy, the mass and volume of the uterus reaches about 1100 grams of mass and approximately 5 liters of volume at the end of pregnancy.
If we believe, the uterine capacity towards the end of pregnancy increases by approximately 500-1000 times compared to pre-pregnancy.
Ovaries called Ovaries do not mature from egg follicles during pregnancy. In short, the development of new follicles is suspended for a certain period of time.
The vessels in the vagina region intensify, where the current blood flow and blood volume increase. For this reason, softening occurs in the connective tissue in the vagen region.
During the last trimester period of pregnancy, an intense strain occurs in the muscles of the abdominal wall. A significant amount of relaxation is observed in the pelvis ligaments. Complaints such as lower back pain and numbness in the hands may occur due to changes in the musculoskeletal system.
Skin and Cracks
With the mechanical strain effect caused by high levels of lubrication and the growth of the uterus, the skin in the abdominal area may develop lines due to collagen fractures, i.e. cracks. These occur in the middle of the skin and blood vessels become visible from the upper skin.
In addition, due to hormonal changes, pigmentation increase and color changes may be observed in the skin. In general, there is an increase in superficial blood flow in the skin.
Changes in the Breast
In early pregnancy weeks, there is usually a feeling of tenderness and fullness in the breasts. After the first trimester period, growth in breast size and vascularization under the skin become apparent.
Nipples can become darker and steeper. From the second trimester period of pregnancy, there may be a discharge called colostrum in yellow and dark from the breasts.
There is no relationship between the increase in breast size and the amount of milk to be synthesized after childbirth. It is also normal that the first milk, which is colostrum, never came during pregnancy. Breasts should not be warned to see if colostrum arrived during pregnancy. This can lead to premature birth.
As the pregnancy period progresses, there are very significant changes in metabolism to meet the needs of the rapidly growing baby and placenta. During the third trimester period, the basal metabolic rate increases slightly compared to pre-pregnancy. This means that, on average, your body needs up to 300 calories of energy a day.
The volume of blood in circulation increases by 40-50% during pregnancy. This increase begins after fertilization during the first trimester period. Both plasma and red blood cells are responsible for the increase in blood volume. However, plasma increases by 50%, while the increase in red blood cells is around 30%. As a result, physiological anemia develops in the mother’s body. Existing blood, iron and ferritin levels decrease.
During pregnancy, the working speed of the heart and the blood volume pumped into the body increased by 20%. Overall, there is a decrease in blood pressure. Heart rate increases by 10 beats per minute depending on the period when you are not pregnant. Because the diaphragm is pressed up, it presses the heart and the heart moves slightly to the left and upwards.
This is the 24th time of the pregnancy that the blood pressure drops. becomes the most prominent in the week. Towards childbirth, it reaches pre-pregnancy values.
During pregnancy, aperture rises about 4 cm. The volume of the lung due to this decreases. This is why fatigue during pregnancy and frequent breath during pregnancy is caused by breathing.
Especially during the last trimester period of pregnancy, a slight increase in kidney size may occur. On average, it can grow by another cm than normal. The expansion of urinary channels may increase the risk of kidney infection. Due to the pressure on the base of the urinary sac towards the end of pregnancy, there is not enough blood flow and the urinary sac becomes prone to infection.
During pregnancy, there is no significant change in the time of ejaculation of the stomach. However, a significant extension occurs during the act of childbirth and especially during the time of gastric ejaculation following the analgesic issuance. Therefore, one of the most important risks of general anesthesia is aspiration of the stomach content.
Especially during the last trimester period of pregnancy, it is common for mothers to escape to the esophagus of the stomach content. Gums take a reder color and the tissues here soften. Gastric ulcers are less common during pregnancy.
However, constipation and related gas complaints can affect almost any pregnant woman as bowel movements slow down. Gallbladder discharge time increases and the predisposition to gallbladder stone increases. Liver function tests are usually normal.
The pituitary gland, located at the tip of the front brain and responsible for the functioning of all hormones in the body, grows during pregnancy. The rate of prolactin levels increases considerably in the blood with pregnancy. After birth, it falls rapidly.
For various reasons, a weakening of memory, attention and concentration can be seen during pregnancy.
