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.
Trauma, rupture of blood vessels or bleeding disorders could result in the accumulation of blood in the abdominal cavity. Heart disease, in which there is failure of the right side of the heart, can also cause fluid buildup in the abdomen as the heart loses its capacity to pump blood. This results in a buildup of pressure in the abdominal cavity and causes fluid accumulation as a result of portal hypertension. Liver disease, inflammation of the kidneys or a decrease in the blood albumin levels are other conditions that result in abdominal fluid buildup.
