Leg ulcers are caused by a lack of oxygen and nutrients to the skin cells that causes them to die. The blood in the body has to move at a sufficient pace and carry an adequate amount of oxygen to the distant tissues in the legs for the skin cells to survive and function. Individuals who have chronic problems with the structure or function of their connective tissues, nerve function, muscle function, and blood vessel function can experience an inadequate amount of circulation in the legs. Regardless of the underlying cause, the necrosis of skin tissues due to oxygen starvation is the most common way leg ulcers develop.
