Edema is swelling of both legs from a buildup of extra fluid. Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Swelling is caused by fluid buildup in the tissues. Gravity pulls the fluids to your feet and ankles, causing them to swell. Swelling can be caused by a serious condition of the kidney, heart, liver or blood vessels. Some other causes of swelling are: 1  Eating a poor diet high in salt and carbohydrates. 2  Taking birth control or hormone replacement therapy pills. 3  Pregnancy.
