Tissue swelling, also known as edema, occurs when excess fluid accumulates in the body’s tissues. This swelling can result from various factors such as injury, infection, or inflammation.

When blood vessels become damaged or dilated, fluid can leak out into surrounding tissues, causing puffiness and bloating. It can affect small, localized areas like the feet or hands, or more widespread areas like the abdomen.

Swelling can be a natural part of the body’s healing process after an injury, as it helps deliver essential nutrients and immune cells to the affected area. However, persistent swelling may indicate an underlying condition, such as an infection or heart problem.

To manage swelling, elevating the affected area, applying cold compresses, or taking anti-inflammatory medications may help reduce fluid buildup. If swelling does not subside or is accompanied by other symptoms, medical attention may be necessary.
