Treatment of edema often means treating the underlying cause of edema. For example, allergic reactions causing edema may be treated with antihistamines and corticosteroids.
Edema resulting from a blockage in fluid drainage can sometimes be treated by eliminating the obstruction:
A blood clot in the leg is treated with blood thinners, and the clot slowly breaks down. Leg edema then resolves as fluid drainage improves.
A tumor obstructing a blood vessel or lymph flow can sometimes be reduced in size or removed with surgery, chemotherapy, or radiation.
Leg edema related to congestive heart failure or liver disease can be treated with a diuretic such as furosemide (Lasix). When urine output increases, more fluid drains from the legs back into the blood. Maintaining a sodium-restricted diet will also help limit fluid retention associated with heart failure or liver disease.
