What condition is caused by excess fluid trapped in your body's tissues?

1. Inflammation

2. Edema

3. Dehydration

4. Infection

The correct answer is: Edema

Edema is the condition characterized by an excess accumulation of fluid in the tissues of the body. This excess fluid can cause swelling, particularly in areas like the arms, legs, and abdomen, and it often results from various underlying issues such as heart problems, kidney disease, or inflammation. Understanding edema also helps differentiate it from other conditions mentioned in the options. While inflammation can cause temporary swelling due to increased blood flow and immune response, it is not solely defined by fluid accumulation throughout the body’s tissues. Dehydration refers to a deficit of fluid in the body, which is the opposite of edema. Infection can lead to swelling as well, but it is typically associated with localized inflammation and the body’s immune response rather than a general accumulation of fluid. Thus, edema precisely addresses the issue of excess fluid trapping in the body's tissues.
