Swollen ankles and calves in pregnancy: what to know

Pregnancy increases circulating fluid, and the growing uterus can make it harder for blood to return from the legs. Swelling may be more noticeable later in the day or after standing, and both feet may be affected. It should not be assumed to be a normal pregnancy change when it begins suddenly or is much greater on one side. A blood clot, high blood pressure disorder, heart failure, or kidney disease can also cause concerning symptoms and requires clinical assessment.

Rest with your legs supported, change position often, and move your feet and ankles gently. Choose comfortable shoes and avoid socks that leave deep tight bands. Staying hydrated and following your maternity team’s advice about activity can help. Do not restrict fluids, take water tablets, or use compression stockings without asking your maternity clinician; the right approach depends on your circulation and other health conditions. Keep appointments where blood pressure and urine are checked, and mention any new swelling rather than waiting for the next visit if it is marked.

Contact your maternity team urgently for sudden swelling of the face or hands, a severe headache, visual changes, pain below the ribs, or feeling very unwell. Seek emergency help for chest pain, trouble breathing, faintness, or a swollen painful warm calf, especially when one leg is affected. Prompt review is also needed if swelling rapidly increases, your blood pressure is high, or you notice a clear change in urination.

Is this pattern consistent with pregnancy-related swelling? Should my blood pressure and urine be checked sooner? Are compression garments or particular exercises appropriate for me?
