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.
Diabetes also can lower the amount of blood flow in your feet. Not having enough blood flowing to your legs and feet can make it hard for a sore or an infection to heal. Sometimes, a bad infection never heals. The infection might lead to gangrene.
