ABSTRACTEdema is an excess of interstitial fluids. Different causes of edema include transudates due to decreased oncotic capillary pressure (e.g. nephrotic syndrome, liver cirrhosis) or increased hydrostatic capillary pressure (e.g. congestive heart failure). These may be associated with a secondary hyperaldosteronism with the subsequent retention of water and sodium. Edema secondary to exudates is due to increased in the blood vessel permeability to the blood proteins (e.g. during infecction), or secondary to lymphatic tissue obstruction (e.g. neoplasias) causing localized edema in the involved body part. Edema can be related to drugs (e.g. calcium antagonists), endocrinopathies (e.g. hypothyroidism), accumulation of the fat deposits in the subcutaneous tissue (e.g. lipedema), or may be idiopathic. Treatment of edema depends on the underlying etiology.
