What condition is associated with overhydration and swelling of tissues?

Edema is the condition that is characterized by overhydration and the resultant swelling of tissues. When the body retains too much fluid, it leads to an accumulation of interstitial fluid, causing swelling in various parts of the body. This can happen due to various reasons, such as heart failure, kidney dysfunction, or certain medications that affect fluid balance.

This physiological response is often visible in areas such as the legs, ankles, and around the eyes. The presence of edema can be indicative of underlying health issues and is an important symptom that healthcare providers assess when evaluating a patient's condition.

In contrast, necrosis refers to the death of cells or tissues, often due to inadequate blood supply or infection, while ischemia describes a deficiency in blood supply to an organ or tissue. Dehydration, on the other hand, is the opposite of overhydration and involves a loss of body fluids, which leads to a reduction in bodily functions.
