Most women experience edema in late pregnancy due to compression of the inferior vena cava, and a few pregnant women also experience edema due to disease.
After pregnancy, the uterus will continue to increase in size. In the late stage of pregnancy, the uterus has increased in size to a certain extent, often compressing the inferior vena cava, leading to a decrease in blood return to the lower limbs, and an increase in the pressure in the veins of the lower limbs, which makes it easy to develop the symptoms of oedema of the lower limbs. If a woman in late pregnancy is often in a standing position, it is easy to cause further aggravation of the symptoms of edema.
If a woman in late pregnancy suffers from gestational hypertension syndrome, hypoproteinemia, severe anemia, nephrotic syndrome and other diseases, edema also often occurs, and this kind of edema is usually more serious, and it can not be improved after resting, so it is necessary to consult a doctor in time.
