How big is the 4 month old belly

A 4-month-old belly is actually very obvious. Many pregnant women can clearly feel that their belly has a sense of sinking and weight, and there will also be a slight bulge. This will cause pregnant women to feel uncomfortable, especially when bending over, it will be a bit strenuous, but not so obvious. In addition, their breasts will also undergo some changes and become larger.

Belly changes: As the fetus grows, the belly gradually gets bigger, and the burden on the body increases.

Pulse changes: pulse rate increases by 10 beats per minute, breathing rate increases: heart rate increases by 10 to 15 times

Metabolism: Metabolism accelerates: metabolic rate increases by 10% to 25%

Uterine changes: Thickening and lengthening of uterine muscle fibers

Breast changes: Breasts become larger and softer, and milk ducts increase

The fetus grows and develops very quickly in the mother's body. In the first 8 weeks after pregnancy, the fertilized egg develops from a single cell into a formed human body with 200 million cells. This period is called an embryo; after 8 weeks of pregnancy, it is called a fetus. At 6 weeks of pregnancy, the embryo's spine and brain begin to form, and the heart begins to beat. B-ultrasound can measure the activity of the embryo and heart. At this time, the pregnant woman may have early pregnancy reactions. After 7 weeks, limbs begin to form.

After 8 weeks, the embryo has eyes but no face or external auditory canal; the embryo begins to move, but the pregnant woman cannot feel it yet. At 12 weeks, the fetus is about 7 cm long and weighs 20 grams. It has a human shape and its head appears larger than other parts of the body. The fetal heart rate can be heard using a Doppler stethoscope. The fundus of the uterus can be felt above the pubic symphysis through the abdomen.

The most important thing to note in early pregnancy is to supplement folic acid, because expectant mothers' demand for folic acid throughout the pregnancy is 1.5 to 2 times that before pregnancy. Taking 0.4 mg of folic acid per day in early pregnancy can greatly reduce the incidence of fetal neural tube defects and prevent birth defects in newborns.

Severe pregnancy reactions can also affect the appetite of expectant mothers, and nutrition will naturally not keep up. Tangerine peel, which has the effects of promoting qi and strengthening the spleen, warming the stomach and stopping vomiting, and Chinese yam, which can strengthen the spleen and stomach, and replenish qi, can effectively relieve pregnancy reactions.

After pregnancy, women's blood volume increases, which can easily cause physiological anemia, resulting in a decrease in the blood's ability to transport nutrients to the baby, affecting the baby's growth and development. During pregnancy, you can supplement iron appropriately and increase the consumption of honey, jujube, wolfberry, yam, lotus seeds, tangerine peel, enoki mushrooms, etc., especially jujube, which contains ferrous ions. Ferrous ions are mainly used to synthesize red blood cells and maintain the normal concentration of blood. Combining Chinese and Western medicine can comprehensively replenish the blood.
