Due to the fluid needed by the fetus and placenta, a pregnant woman's body retains more sodium and water than usual, increasing the risk of edema.
Your risk of edema may be increased if you take certain medications, including:
- High blood pressure medications
- Nonsteroidal anti-inflammatory drugs
- Steroid drugs
- Certain diabetes medications called thiazolidinediones
If you have a chronic illness such as heart failure, liver or kidney disease, your risk of edema increases, as well. Surgery can sometimes obstruct a lymph node, leading to swelling in an arm or leg, usually on just one side.
