A certain amount of swelling (called edema) is normal during pregnancy. It occurs most often in the legs. Elevating the legs usually makes the swelling less by the next morning. Swelling can begin during the last few months of pregnancy, and it may occur more often in the summer.
Let your doctor or nurse know if you have swelling in your hands or face, because this may be a sign of another problem. A clue that your hands are swollen is that your rings are too tight. Never take medications (water pills) for swelling unless they have been prescribed for you.
Elevate you legs when possible.
Rest in bed on your side.
Lie down with your legs raised on a small footstool or several pillows.
Do not wear stockings or socks that have a tight band of elastic around the legs.
If you must sit a lot on the job, stand up and move around from time to time.
Try not to stand still for long periods of time.
