Which form of edema may be caused by generalized passive hyperemia?

Anasarca refers to a severe and generalized form of edema that affects the entire body. It typically occurs when there is an imbalance in the body's fluid regulation, often linked to conditions such as heart failure, liver failure, or significant changes in capillary permeability. Generalized passive hyperemia leads to fluid accumulation throughout the body as a result of impaired circulation and increased hydrostatic pressure in the blood vessels, causing widespread leakage of fluids into the interstitial spaces.

In this context, generalized passive hyperemia results in the body retaining fluid excessively, culminating in anasarca. The other forms of edema mentioned, such as localized edema or exudate edema, are typically associated with specific local inflammatory processes or localized conditions rather than with the general systemic effects leading to anasarca. Pulmonary edema, while a type of fluid accumulation, is more specific to the lungs and does not encompass the generalized aspect of anasarca caused by systemic conditions.
