Leg swelling occurs several months into pregnancy

Leg swelling occurs several months into pregnancy

I believe everyone knows the importance of pregnancy to female friends. If female friends do not take good care of themselves during pregnancy, it is easy to have various problems. Problems during pregnancy will not only harm the pregnant woman herself but also easily affect the development of the fetus. Therefore, we recommend that pregnant women do a good job of self-care in daily life. Below we will introduce how leg swelling will occur in a few months of pregnancy.

What causes swollen feet during pregnancy?

1. After pregnancy, the blood volume of pregnant women begins to gradually increase from the 6th week of pregnancy, reaches a peak at 34 weeks, and remains at this level until two weeks after delivery, when it returns to the pre-pregnancy level. Blood volume can increase by about 40% compared to the non-pregnant period, so as blood volume increases, interstitial fluid will also increase.

2. Because the increase in plasma is greater than the increase in blood cells when blood increases, the blood components will be relatively diluted and the relative concentration of plasma albumin will be lower than that in the non-pregnant period. Plasma albumin is the main component that maintains plasma osmotic pressure. Plasma osmolality is lower during pregnancy than during non-pregnancy. This makes it easy for water in the blood to penetrate into the interstitial fluid, causing lower limb edema.

3. After pregnancy, the uterus enlarges, which increases the pressure in the pelvis, thereby affecting the venous blood flow in the lower limbs. This is also one of the important reasons for lower limb edema. If the swelling during pregnancy is relieved after rest or sleep, it is physiological and there is no need to worry.

The above reasons for swelling are normal phenomena. However, if the edema is obvious and does not improve, further examination should be conducted to determine if there are other pregnancy complications, and timely diagnosis and treatment should be provided.

In the above article, we introduced a symptom that pregnant women are prone to during pregnancy, that is, swollen feet. We know that swollen feet bring many troubles to pregnant women. The above article shows how many months of pregnancy will cause swollen legs. I believe everyone understands it.
