Edema

Edema is an observable swelling that occurs due to the accumulation of fluid in body tissues. Edema most commonly occurs in extremities like feet, ankles, legs, or hands where it is referred to as peripheral edema. There are a number of other different types of edema, usually named after the part of the body affected.

Mild edema is common and does little harm. It can develop due to spending too much time sitting or staying in bed (immobility), due to varicose veins, and pregnancy. Certain medications, allergies, or more serious underlying ailments including heart failure, liver disease, and kidney disease can also cause edema.

Dietary modifications like decreasing dietary sodium intake can help reduce fluid overload. Treatment includes use of diuretics like furosemide, and bumetanide, which can reduce edema fluid. Patients on these diuretics are commonly advised to take potassium supplements or consume foods rich in potassium such as bananas, orange juice, tomatoes, potatoes etc.
