Ulcers are open skin sores, which can affect any area of the skin. Normally, when you get injured (cut or scrape), the healing process starts to close the wound. Over time, the wound heals. However, with venous ulcers, that is not the case; it requires proper treatment.
Mainly, they occur on the legs.
To understand more about it, keep reading.
Blood circulation disorders of leg veins cause venous ulcers (open sores) of the leg. When veins in the legs do not push the blood back to the heart as they should, which causes blood to back up in the veins, which builds up the pressure. If not treated, the increased pressure and excess fluid in the affected area may result in an open sore.
Most venous ulcers chiefly occur above the ankle area on the leg. Such wounds take time to heal.
The primary cause of venous ulcers is high pressure in the veins of the lower leg. The veins have valves that prevents blood from flowing backward and help upward return of blood to the heart. When the valves become weak or damaged, the blood may flow backward and cause blood to pool in the veins. This is called venous insufficiency, which leads to high pressure in the lower leg veins. The increase in pressure and building of the fluids inhibits tissues from getting oxygen and nutrients, which further causes cells to die, damage the tissues, and may result in wound formation.
Risk factors for venous ulcers include:
Pooling of the blood in the veins of the lower leg results in fluid and blood cells leak out into the skin and other tissues. This may cause itchy, thin skin and lead to skin changes called stasis dermatitis, an early sign of venous insufficiency.
Other early signs of venous insufficiency include the following:
Signs & symptoms of venous ulcers include:
Lifestyle changes can help to prevent venous ulcers. The following measures may help to improve blood flow and help the wound to heal:
Stay vigilant and inspect your feet and legs every day for cracks and changes in skin color.
Various treatment options are available for treatment of venous ulcer.
