Mild swelling of the ankles, feet, and fingers is common in pregnancy, especially in the third trimester, as the body retains more fluid and the growing uterus puts pressure on veins returning blood from the legs. It tends to build up over the course of the day and is often worse in hot weather or after standing for long periods.

What is Swollen Ankles, Feet and Fingers in Pregnancy?
Mild swelling of the ankles, feet, and fingers is common in pregnancy, especially in the third trimester, as the body retains more fluid and the growing uterus puts pressure on veins returning blood from the legs. It tends to build up over the course of the day and is often worse in hot weather or after standing for long periods.
While usually harmless, sudden or severe swelling — especially of the face or hands, or alongside other symptoms — can be a sign of pre-eclampsia and needs prompt assessment.

Clinical context

Practical steps
Know the Difference Between Typical and Concerning Swelling
Mild, gradual swelling in both feet by the end of the day is typical. Sudden swelling, or swelling with other symptoms, is not — always report these.
- 1Elevate your feet when resting.Propping your feet up above heart level when sitting can help reduce fluid build-up.
- 2Stay active with gentle movement.Walking and ankle exercises support circulation and reduce swelling.
- 3Avoid standing or sitting for long periods.Take regular breaks to move if you've been in one position for a while.
- 4Wear comfortable, supportive footwear.Avoid anything tight or restrictive as your feet may naturally swell.
- 5Reduce time in the heat.Swelling tends to worsen in hot weather, so stay cool where possible.
