Many women develop mild swelling in the face, hands, or ankles at some point in their pregnancies. As the due date approaches, swelling often becomes more noticeable. 

What might help: 
•    Drink eight to 10 glasses of fluids daily. 
•    Don't drink caffeine or eat salty foods. 
•    Rest and elevate your feet. 
•    Ask your doctor about support hose. 
Call your doctor if your hands or feet swell suddenly or you rapidly gain weight — it may be preeclampsia.
