Swollen ankles and feet in pregnancy: what to know

Pregnancy increases the amount of fluid in the body, and the growing womb can slow blood returning from the legs. Swelling often becomes more noticeable later in the day, after standing, or in warm weather, and may affect both feet fairly evenly. Varicose veins can add to heaviness or ankle swelling.

Swelling alone does not identify its cause. A clinician may check your blood pressure, urine, legs, and overall symptoms to look for pregnancy complications or other conditions affecting fluid balance.

Rest with your legs supported, change position regularly, and take gentle movement such as walking if your maternity team says it is suitable. Choose comfortable shoes and avoid tight socks or clothing around the legs. Sleeping on your side may be more comfortable than lying flat on your back.

Keep routine antenatal appointments so changes in swelling, blood pressure, and urine can be reviewed. Do not take water tablets or use compression garments without professional advice, because the right approach depends on the pattern of swelling and your health.

Contact your maternity team promptly if swelling appears suddenly, affects the face or hands, comes with a severe headache, vision changes, pain under the ribs, or feeling very unwell. Seek urgent help for one leg that is painful, hot, red, or much more swollen than the other, or for chest pain or breathlessness.

Ask whether your swelling pattern needs a blood pressure or urine check, whether support stockings are appropriate, and which exercises are suitable. Mention any previous kidney, heart, or vein problems and ask which changes should trigger an urgent call.
