Overview

You may have some mild swelling because of normal fluid buildup during pregnancy. It's most common in the face, hands, and feet.

As your pregnancy continues, your uterus puts pressure on blood vessels that go to your legs. This may cause swelling in your feet and ankles. Normally, foot swelling gets worse during the day and goes away at night. Symptoms may develop slowly or suddenly.

It may help to prop up your feet when you're sitting, avoid high-sodium foods, and wear support stockings.

Call your doctor if you have sudden swelling of the face and hands that doesn't go away during the day. This may be a symptom of preeclampsia, which can be dangerous if not treated. Preeclampsia may also cause other symptoms, such as rapid weight gain—more than 2 lb (0.9 kg) a week.
