How to reduce leg swelling during pregnancy

Pregnancy can increase fluid in the body and put pressure on veins returning blood from the legs. Swelling is often more noticeable in the feet and ankles later in the day or after standing. Both sides may be affected. A sudden increase, especially in the face or hands, is different and should be discussed promptly because it can accompany a pregnancy-related blood pressure problem. One painful, warm, or noticeably larger leg also needs assessment.

Take regular gentle walks if your maternity team has not restricted activity, and move your ankles while sitting. Rest on your side or with your lower legs supported by cushions. Avoid standing still for long periods, crossing your legs, and tight bands around the calves or ankles. Choose roomy shoes and stay hydrated. Ask your maternity clinician before using compression socks, medicines, herbal products, or a low-salt diet; safety depends on your pregnancy and medical history.

Contact your maternity team urgently for sudden swelling of the face or hands, a severe headache, vision changes, pain below the ribs, or feeling very unwell. Seek urgent care for one-sided leg swelling with pain, warmth, or redness, or for breathlessness and chest pain. Do not wait for a routine appointment if these symptoms occur. For swelling that is gradual but troublesome, ask about blood pressure checks and whether another cause should be considered.

Ask whether your swelling pattern is expected, how to check your blood pressure, and whether compression is appropriate. Tell the clinician when it started, whether it is equal on both sides, and which symptoms occur with it.
