What is venous disease? Venous disease is a group of conditions that affect the veins in the legs and can cause pain in the legs, varicose veins, swelling in the legs or open sores. Varicose veins are swollen and twisted veins. Vein disease is prone to occur when the veins in the legs are not working properly. Normally, blood is able to return from the legs to the heart. The walls of the veins contain tiny valves that keep the blood flowing in one direction (toward the heart). When the valves are open, blood flows toward the heart; when they are closed, blood does not flow backwards. Venous disease occurs when venous valves are damaged or do not work properly, causing blood to collect in the legs, especially when they are sedentary and when you stand for long periods of time without moving around. What conditions can cause venous disease? 1.Blood clots in the leg veins; 2.Injuries to the legs; 3.Multiple pregnancies: this can lead to changes in hormone levels in the body, which can weaken the vein walls. 4, weight gain; 5, in addition, vein disease may run in families. What are the symptoms of venous disease? There can be the following symptoms, including: 1. Pain in the legs, or feeling weak and heavy with swollen veins: “Spider veins” are small veins in the legs that swell. “Varicose veins” are swollen and twisted large veins in the legs. 2. Swelling of the calf or ankle: appears in the evening or persists. 3. Change in skin color: turns red or reddish-brown, often first around the ankle. 4. Open ulcers, also known as “venous ulcers”: usually occurring in the ankle joint, the ulcers cause pain with oozing. Are there tests to diagnose venous disease? Yes. Your doctor or nurse will do a physical examination of your leg and may also do an ultrasound, which will check to see if the leg valves are working properly and to assess for blockages in the veins.
