What does the term "anasarca" refer to?

The term "anasarca" refers to severe generalized edema, which is characterized by widespread swelling affecting the entire body. This condition results from the accumulation of excess fluid in the interstitial spaces, leading to pronounced puffiness and distension in various parts of the body, including the extremities and trunk. Anasarca may be indicative of underlying health issues such as heart failure, renal failure, or liver disease, where the body's ability to manage fluid balance is severely compromised.

Localized edema, fluid accumulation in the abdomen, and swelling of the face are specific types of fluid retention that do not encompass the broad and severe nature of anasarca. While localized edema affects only certain areas of the body, anasarca signifies a systemic condition that is more serious and reflects significant fluid imbalance.
