What is the condition called when there is an accumulation of fluid in the tissues?

The condition characterized by an accumulation of fluid in the tissues is known as edema. Edema occurs when the balance of fluids within the body is disrupted, leading to excess fluid leaking into the surrounding tissues. This can happen for various reasons, such as increased capillary permeability, venous obstruction, or heart failure, among others.

Edema can manifest in different parts of the body, including the legs, ankles, and lungs, and is often seen in clinical settings as a symptom of underlying health issues. The accumulation of fluid can lead to swelling, discomfort, and in some cases, further complications depending on its location and severity.

Understanding edema is crucial for identifying and managing health conditions, as it provides valuable diagnostic information regarding the patient's overall fluid balance and circulatory health.
