What is the term for a condition characterized by swelling mainly in the feet and ankles?

The term for a condition characterized by swelling mainly in the feet and ankles is edema. Edema refers to an accumulation of fluid in the interstitial spaces, which can occur for various reasons, including heart failure, venous insufficiency, or prolonged standing. This condition specifically affects the lower extremities because gravity causes fluid to pool in the legs and feet when standing or sitting for long periods.

In contrast, lymphoma is a type of cancer that affects the lymphatic system, and while it may cause swelling, it typically presents in lymph nodes rather than predominantly in the feet and ankles. Acute kidney injury refers to a sudden decline in kidney function, which can lead to fluid retention and edema, but it is not specifically defined by swelling in the feet and ankles. Skin cancer relates to abnormal growths on the skin and does not involve swelling in the manner described. Understanding these distinctions helps clarify why edema is the most appropriate term for this condition.
