Edema is characterized by the collection of excess fluid in the interstitial space.<unk>  is severe edema characterized by generalized swelling throughout the body. The main underlying cause of edema is an imbalance in the hemodynamic status of the capillaries resulting in excess filtration of fluid in the intercellular space due to increased hydrostatic pressure, increased permeability of the capillaries and decreased oncotic pressure. It exceeds the absorptive capacity of lymph vessels. It can be caused by systemic diseases including chronic heart failure, liver cirrhosis, hypersensitivity reaction, and chronic renal failure.
