Venous insufficiency is caused by damaged valves in the veins of the legs which allows blood to flow in the wrong direction.
This can result in swelling as excess fluid escapes into the tissue of the legs. This condition can result in varicose veins, leg pain and venous ulcer of the lower legs. Heredity, obesity, heart failure and high blood pressure are the leading risk factors for venous insufficiency. Patients often get relief from symptoms with weight loss and proper use of medical grade compression garments.
