Edema (British English: oedema, formerly known as dropsy) is swelling of any Organ (anatomy) or Biological tissue due to accumulation of excess fluid. Edema has many root causes, but its common mechanism is accumulation of fluid into the tissues. Types of edema are ''pitting edema'' and ''non-pitting edema''. The former is present if pressing of the affected body part creates a small pit that disappears within a few seconds. Non-pitting edema is not compressible. Edema can occur in whole body, then it is called ''generalized'', or can be limited to only some parts or organs, then it is ''localized''. Causes of edema are: * high hydrostatic pressure of the veins, leading to poor reabsorption of fluid ** venous obstruction ** congestive heart failure ** varicose veins * low oncotic pressure ** cirrhosis ** malnutrition ** nephrotic syndrome (renal protein loss) * inflammation (active secretion of fluid into the interstitial space): ** allergy conditions (e.g. Angioedema) ** any other form of inflammation (''tumor'' - or swelling - is one of the main characteristics of inflammation) == See also == * Pulmonary edema * Anasarca * [http://www.nlm.nih.gov/medlineplus/ency/article/003103.htm Medline Encyclopedia - Swelling] pathology
