Edema is the swelling of tissues as a result of excess water accumulation. Peripheral edema occurs in the feet and legs. There are two types of edema, non-pitting edema and pitting edema. Causes of pitting edema is caused by systemic diseases (most commonly involving the heart, liver, and kidneys), and medications. Local conditions that cause edema are thrombophlebitis and varicose veins. Edema or swelling of the legs, feet, ankles, and face are common during pregnancy. Idiopathic edema is edema in which the cause is not known. Pitting edema is scored on pitting edema measurement scales. Edema is generally treated with medication.Read more: Edema Article
