Swelling is extremely likely to occur during pregnancy, particularly towards the third trimester. The hands and feet are the most likely locations for swelling to occur, though any part of the body can have a swollen feeling.
What causes it?
Swelling is likely to occur as pregnancy progresses due to the increased fluids that the body contains while carrying a child, both in blood and water. Blood will often pool at the feet, as your heart works against gravity to pump it out. Abdominal swelling is more likely caused by excess water build up or your expanding womb pressing against its neighbors.
Tips?
Even though it is slightly counter-intuitive, staying well-hydrated is one of the best ways to combat swelling. Because swelling in the feet is a result of poor circulation, staying active can help your blood flow efficiently. Most swelling disappears after pregnancy as you pee and sweat out your excess fluids.
