If you have persistent wounds, it may indicate a problem with the circulatory (vascular) system.
Poor circulation to the legs and feet may reduce the supply of blood – and oxygen – to a wound. This restricts the body’s immune response, making healing more difficult.
Peripheral vascular disease or peripheral arterial disease, for example, is a narrowing of arteries that may be linked to atherosclerosis, which can impede blood flow to the legs and feet.
People with wounds may suffer from venous insufficiency, for example, where the veins struggle to return blood to the heart. Venous insufficiency may cause varicose veins – where inefficient valves within the veins allow blood to pool – may progress to venous ulcers.
In fact, the vast majority of lower extremity wounds manifest because of an underlying vascular issue. An estimated 80 percent of chronic leg and foot wounds are caused by venous disease, according to Medscape.
Some other vascular diseases associated with wounds include:
- Venous hypertension
- Deep vein thrombosis (DVT)
- Buerger disease
- Raynaud’s disease
