Swollen legs are something many people experience, especially after spending hours sitting, standing, traveling, or during hot weather.
In many cases, the swelling is temporary and has a relatively simple explanation.
But when it keeps returning, becomes worse, or appears without an obvious reason, it may deserve medical attention.
One possible cause that people may overlook is advanced liver disease. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), cirrhosis can cause swelling in the lower legs, ankles and feet, a condition known as edema.
