Edema is swelling caused by excess fluids that is caught up in your body’s tissues. Though edema can affect any part of your body, you may see it more in your extremities
Edema can occur due to medicines, pregnancy or an illness such as heart failure, kidney disease or liver cirrhosis.
Taking drugs to remove excess fluids and lessening salt in your diet frequently relieves edema. At the point when edema is the symptom of a disease, the disease itself requires separate treatment.
