Some swelling is normal in the hands, face, legs, and feet during your pregnancy, especially towards the end. Continue to drink plenty of water, avoid high sodium foods (pretzels, potato chips, salted popcorn, etc.) Exercising and elevating your legs when able will also help.
Make sure to notify your nurse if you have a sudden increase in swelling. This can be a sign of preeclampsia, which is a serious medical condition and will need to be treated right away.
