Edema (American English) or oedema (British English) (/ɪˈdimə/; from the Greek οἴδημα—oídēma, "swelling"), formerly known as dropsy or hydropsy, is an abnormal accumulation of fluid in the interstitium, which are locations beneath the skin or in one or more cavities of the body. It is clinically shown as swelling. Generally, the amount of interstitial fluid is determined by the balance of fluid homeostasis, and increased secretion of fluid into the interstitium or impaired removal of this fluid may cause edema.Source: Wikipedia
