Feet swelling in pregnancy

Pregnancy changes how your body holds and moves fluid. The growing uterus can also slow the return of blood from the legs, so swelling may be more noticeable in the feet and ankles after standing or later in the day. Both sides may be affected, and the swelling can feel tight without being painful.

Swelling itself does not establish a diagnosis. Pre-eclampsia is a condition that can present with swelling alongside high blood pressure or symptoms such as a severe headache, vision changes, or pain beneath the ribs. The combination and timing matter, so report changes rather than trying to judge the cause at home.

Change position regularly, take comfortable walks if your pregnancy team has said activity is suitable, and rest with your feet supported. Choose roomy shoes and avoid tight socks around the ankles. Side-lying rest may feel more comfortable for some people. Drink normally and continue your usual antenatal appointments.

Do not start water tablets, herbal remedies, or compression garments without checking with your clinician. Mention swelling that makes shoes difficult to wear, appears early in the day, or continues after rest so your blood pressure and urine can be checked when appropriate.

Contact your maternity team promptly if swelling appears suddenly, becomes much more pronounced, affects your face or hands, or comes with a severe headache, blurred vision or flashing lights, pain beneath the ribs, feeling very unwell, or reduced urination. Seek urgent help for chest pain or sudden difficulty breathing.

Painful swelling that is mainly on one side, with warmth, redness, or calf tenderness, also needs prompt assessment. These warning patterns require clinical review even when you have otherwise felt well.

Ask whether your swelling pattern needs a blood-pressure or urine check, what level of activity is appropriate, and which measures are safe for comfort. Tell them when the swelling began, whether both feet are affected, and whether it changes after rest.
