Swollen ankles in late pregnancy: what to know

Pregnancy increases the amount of fluid in the body, while the growing womb can press on veins returning blood from the legs. Swelling may be more noticeable later in the day, in warm weather, or after standing. It often affects both feet and ankles. Sudden swelling of the face or hands, a severe headache, vision changes, pain below the ribs, or feeling very unwell can be warning signs of a pregnancy complication and should not be dismissed as ordinary oedema.

Change position regularly, rest on your side when comfortable, and raise your feet while sitting. Wear supportive, roomy footwear and avoid tight socks or standing for long stretches. Gentle ankle movements and short walks may help circulation if your maternity team has said activity is suitable. Keep appointments and mention swelling at your next check, particularly if it is new or steadily increasing. Do not take medicines or herbal products for swelling unless your maternity clinician recommends them.

Contact your maternity unit promptly if swelling appears suddenly, is much greater on one side, or comes with headache, visual disturbance, upper-abdominal pain, breathlessness, chest pain, or reduced fetal movement. A painful, hot, red leg also needs urgent assessment. Emergency symptoms such as severe breathlessness, collapse, or chest pain require emergency help.

Is my swelling pattern expected for this stage of pregnancy? Should my blood pressure and urine be checked sooner? Which symptoms mean I should call the maternity unit immediately? Are compression socks or particular exercises suitable for me?
