Pedal oedema in pregnancy: what to know

Pregnancy changes how the body handles fluid, while the growing womb can slow blood returning from the legs. Swelling may be more noticeable later in the day, after standing, or in warm weather. Shoes and rings can feel tighter. Mild swelling that affects both feet and improves after rest is often managed with comfort measures, although your maternity team should interpret it alongside your blood pressure and other symptoms.

Take regular movement breaks rather than standing still for long periods. Put your feet up when resting, avoid tight socks or footwear, and choose supportive shoes. Sleeping on your side may feel more comfortable. Gentle ankle movements can encourage circulation. Do not start water tablets, supplements, or a restrictive diet for swelling unless a clinician has advised them. Keep routine antenatal appointments so blood pressure and urine can be checked.

Contact your maternity service promptly if swelling appears suddenly, becomes pronounced in the face or hands, or comes with a severe headache, vision changes, pain beneath the ribs, feeling very unwell, or reduced urine. These symptoms can occur with pre-eclampsia, which needs timely assessment. One-sided leg swelling with pain, warmth, or breathlessness also requires urgent medical attention.

Ask whether your pattern of swelling is expected, whether your blood pressure and urine results are reassuring, and which changes should prompt a call. You can also ask about safe activity, footwear, and whether compression support is suitable for you.
