What is the medical term for swelling of body tissues with water?

Edema is the medical term that specifically refers to the accumulation of excess fluid in the body's tissues, leading to swelling. This condition can occur in various parts of the body and can result from a variety of causes, including injury, inflammation, heart failure, and certain medical conditions. When swelling occurs due to this fluid buildup, it can lead to visible signs such as swelling in the legs, ankles, or hands, and may cause discomfort or other complications depending on the severity and location.

In contrast, dysuria is a term used to describe painful urination, dyspnea refers to difficulty or labored breathing, and dysphagia indicates trouble swallowing. Each of these terms relates to specific symptoms or conditions affecting different body systems, which highlights the distinct nature of edema as purely related to fluid retention and tissue swelling.
