👉 Excessive fluid, also known as edema, occurs when there's an abnormal buildup of fluid in the body's tissues. This can be due to various factors, including heart failure, kidney disease, liver cirrhosis, or prolonged standing. The excess fluid disrupts the normal balance of body fluids, leading to swelling, particularly in the legs, ankles, and feet. This condition can cause discomfort, pain, and impaired mobility, and if left untreated, it may lead to more serious complications.
