How do pregnant women prevent edema

Patient's question:

No

Doctor's answer:

There are many causes of edema: the compression of the inferior vena cava by the pregnant uterus, which obstructs venous blood, and hormones secreted by the placenta, among others. It is recommended that you press your foot with your fingers or your calf with your hand. If there is a noticeable indentation, it means you have edema.
