ABSTRACT
Edema 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.
