Internal physical changes During Pregnancy
1. Changes in metabolism-
- The body of the mother require more nutrition, foetus requires more nutrition due to breastfeeding, growth and development in uterus causes metabolic changes. Stomach secretions reduce as a result of which food stays a bit longer in the stomach. Intestinal muscles relax in the presence of progesterone hormone. Constipation, vomiting, nausea are common problems.
2. Changes in urinary tract-
- Blood circulation towards the kidneys increase and so the kidneys have to work more. The glomerular filtration rate increases by 50%, as a result more urea is removed. Because of this, the rate of glucose re-absorption decreases and more glucose is ousted with the urine. Because of excessive progesterone secretion urinary tract swells and grows curvy.
3. Changes in blood circulation-
- Due to increase in blood in the body, the heart has to work more. Volume of tissues increases. The hamoglobin percentage in blood decreases. Blood pressure too increases by the 4-5″ month. Due to increase in blood pressure, blood vessels in the legs undergo inflammation.
4. Respiration related changes-
- The growing uterus exerts pressure on muscles as a result respiration becomes difficult.
5. Hormonal changes-
- Adrenocorticol hormones and thyrotropin becomes more active during pregnancy. Corticosterone hormone is secreted in excess from the adrenal glands as result some marks appear on stomach. Breathing becomes shallow due to presence of progesterone hormone in the blood. Thyroid gland too grows in size.
6. Changes in vascular system-
- Due to changes in vascular system, the expecting mother experiences stress, fear, anxiety, headache, etc.
7. Changes in vaginal tract, cervix and uterus-
- Hormones affect the reproductive organs. Estrogen causes the mucosa of vaginal tract thicker and the color turns blue. Blood vessels increases in cervix and cervical connective tissue becomes more receptive.
8. Changes in abdomen and pelvic joint-
- Growth of stomach cause the skin to stretch whereby the skin becomes flexible and breaks. As a result, wrinkles appear on stomach.
