The term STEM SWELLING can be summarized as an abnormal accumulation of fluid in the body, which is also known as EDEMA (5 letters). EDEMA is a medical condition that occurs when excess fluid builds up in the body's tissues, causing swelling. It can affect any part of the body, including the arms, legs, feet, ankles, and face. EDEMA is usually caused by an underlying medical condition, such as heart failure, kidney disease, or liver disease. Treatment for EDEMA depends on the underlying cause, but may include medications, lifestyle changes, and physical therapy.
