أمراض الأوردة

Healthy veins have valves that allow blood to flow towards the heart and then valves close to prevent the flow in the opposite direction. When standing, the blood in the veins of the legs must flow upwards against gravity.

In people with varicose veins, these valves can be damaged and allow blood to leak back in the wrong direction and cause what is called venous reflux. This causes stretching of leg veins and pooling of blood where veins become swollen and twisted causing disfigurement and bad appearance of the legs. And also stagnation of blood in the veins can cause blood clots.

Varicose veins, if left untreated, may worsen causing pain and swelling and also  can result in inflammation, itchy sensation and skin thickening with formation of scarred tissue, darkening of skin, and possible ulcer formation which are very difficult to heal. Unfortunately, in some cases over time complications can occur such as bleeding and clots that form inside the main veins and can extend into the deep veins
