Venous insufficiency is a medical condition where the veins in the legs struggle to send blood back to the heart. This occurs when the valves in the veins become weak or damaged, leading to blood pooling in the legs. Symptoms may include swelling, pain, and varicose veins. Treatment options for venous insufficiency can include lifestyle changes, such as exercise and weight management, as well as medical interventions like compression stockings or surgery. Early diagnosis and management are important to prevent complications, such as skin changes or ulcers, associated with this condition.
