The treatment of severe edema in late pregnancy is as follows: 1. Adjust the diet, strictly control the intake of salt, try not to eat some pickled food with high salt content, and at the same time supplement sufficient protein, fresh fruits and vegetables. 2. Pay attention to adjust the sleeping position, usually adopt the left side lying position, which can avoid the compression of the inferior vena cava due to the enlarged uterus and reduce the edema caused by the obstruction of the inferior vena cava blood return. 3. The most suitable way for pregnant women to exercise in late pregnancy is to take a walk, and also to elevate the lower limbs so that the blood in the veins of the lower limbs can flow back to the heart more easily. 4. If the edema is caused by hypertensive syndrome in pregnancy, pre-eclampsia, or impaired cardiopulmonary function, hospitalization is required to provide appropriate dehydration and diuresis, otherwise the safety of mother and baby will be endangered.
