Physiological changes
During pregnancy, due to the needs of fetal growth, gradual and continuous changes will occur in various systems of the mother's body, and the main changes include local changes and systemic changes.
(1) Local changes
Changes in the genitals
1. Uterus
Size: 7 x 5 x 3 cm for non-pregnant → 35 x 22 x 25 cm for full term pregnancy.
Capacity: 5ml at non-pregnancy → 5000ml at full term of pregnancy, an increase of 1000 times.

2. Breasts
Breast enlargement, hyperemia, superficial vein bulge. Conscious breast swelling, enlarged nipple coloring, areola coloring, acinar hyperplasia.
3. Skin
During pregnancy, the secretion of estrogen and progesterone increases, stimulating the anterior lobe of the pituitary gland to secrete melanocyte-stimulating hormone, which acts on the skin and produces melanin, such as nipples, areola, perineum, perianal perianal, abdominal midline, etc. Brown spots appear on the cheeks, forehead and nose of pregnant women, and stretch marks appear in the third trimester of pregnancy.
4. Abdomen
As the month of gestation increases, the uterus gradually enlarges, the internal organs of the epigastric region are squeezed to the top of the abdominal cavity, and the intestinal tubes are squeezed on the upper, posterior and flanks of the uterus, respectively.
(2) Systemic changes
1. Cardiovascular system
The average increase in blood volume is 30%-50%, that is, about 1L-1.5L, and it returns to the level of non-pregnancy at 2-3 weeks after childbirth. Slightly increased white blood cells, diluted blood, blood in a state of hypercoagulability during pregnancy, heart rate increased by an average of 10-15 beats / min.
2. Respiratory system
In the third trimester of pregnancy, the uterus enlarges, the diaphragmatic muscle activity decreases, the thoracic activity increases, mainly chest breathing, hyperplasia of the mucosa of the upper respiratory tract, congestion and edema, weakening the local resistance and prone to infection.
3. Digestive system
Nausea, vomiting, heartburn, hiccups, flatulence and constipation.
4. Urinary system
In normal pregnancy, the kidneys in order to adapt to the increase in metabolism and blood circulation and the need to excrete metabolic waste products from the mother and fetus, the average increase in urine output is 60%-80%, and the uterus enlarges and urinary frequency occurs.
5. Endocrine system
Many endocrine glands such as the pituitary gland, thyroid, adrenal glands, pancreas, etc. are altered by pregnancy during pregnancy.
6. Skeletal system
After pregnancy, the uterus enlarges and the spine bends forward, aggravating the curvature of the lower back, resulting in lower back pain in pregnant women. At the end of the period, pregnant women's shoulders sag and neck flex forward, and the spine of the lower back protrudes forward, so the neck, shoulders and upper limbs of pregnant women are sore. Due to joint relaxation, pregnant women often have a rocking step. When the relaxation is severe, the pubic joint can be separated and uncomfortable.
