Edema

When changes or alterations occur in hydrostatic pressure, oncotic pressure, capillary permeability, and a lymphatic obstruction,- edema will occur. So what is edema?
Edema is an excess accumulation of fluid in the interstitial space. There are two types of edema- localized edema and generalized edema.
Localized edema is as a result of traumatic injury from burns, accidents or surgery or local inflammatory processes. While

In Generalized edema, the excessive accumulation of fluid in the interstitial space does not pertain only to a certain area like localized edema. Here It is accumulated throughout the body (generalized). And it is as a result of conditions such as cardiac, renal, or liver failure.

Another name for generalized edema is anasarca.
