What is the cause of swollen feet of pregnant women? Is edema in pregnant women a normal phenomenon?

1 Causes of foot swelling in pregnant women 1 Increased blood volume.

After pregnancy, the blood volume of pregnant women gradually increased from the sixth week of pregnancy, reached the peak at the 34th week, and remained at this level until two weeks after delivery. The blood volume can be increased by about 40% compared with non-pregnancy period, so the tissue fluid will also increase after the blood volume increases.

2. Water infiltration

With the increase of blood volume, the increase of plasma is more than that of blood cells, so the blood components will be relatively diluted, and the relative concentration of plasma albumin will be lower than that during non-pregnancy. Plasma albumin is the main component to maintain plasma osmotic pressure. Plasma osmotic pressure during pregnancy is lower than that during non-pregnancy In this way, the water in the blood flow can easily penetrate into the tissue fluid, thus causing edema of the lower limbs.

3. Increased pelvic pressure

After pregnancy, the uterus is enlarged, which increases the pressure in the pelvis, thus affecting the venous blood flow of lower limbs. This is also one of the important reasons for edema of lower limbs. If the edema during pregnancy is mild after rest or sleep, it is physiological, so don't worry.

The above causes of edema are normal. However, if the edema is obvious and not relieved, we should further check whether there are other pregnancy complications and make a diagnosis and treatment in time.

2 What should pregnant women do with swollen feet 1, and take enough protein.

Be sure to eat animal food such as livestock, poultry, meat, fish, shrimp, eggs, milk and beans every day. This food is rich in high-quality protein. Pregnant women with anemia should also pay attention to eating animal liver 2-3 times a week to supplement iron.

2. Eat more fruits and vegetables

Vegetables and fruits contain a variety of vitamins and trace elements necessary for the human body, which can improve the body's resistance, strengthen metabolism, and also have the functions of detoxification and diuresis. Pregnant women should not forget to eat vegetables and fruits every day.

3. Don't eat salty food

Eat light food when edema occurs, and don't eat salty food, especially pickles, to prevent edema from getting worse.

Step 4 control water intake

Pregnant women with severe edema should properly control water intake.

5, eat less flatulence food.

Such as fried glutinous rice cakes, sweet potatoes, onions, potatoes and so on. , so as not to cause abdominal distension, poor blood return and increased edema.
