Swelling (Edema) and Diabetes-Swelling in the Legs, Ankles and Feet. Edema commonly affects the ankles, legs, feet and wrists. Edema (known as oedema in the UK) is a build up of fluid in the body (water retention) which causes swelling. Edema commonly affects the legs, ankles, feet and wrist. Water retention is often treatable, with treatment varying depending on the cause.
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.
