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.
Sometimes diseases that affect the entire body, such as heart disease and kidney or liver failure, can result in excess fluid buildup (edema) that is often concentrated in the legs and feet, leading to swelling not only of the ankles but also of the feet and lower legs. This can also occur with pregnancy.
