Ulcers are caused due to a breach in the skin which fails to heal. Initiated by injuries, skin infections, poor blood circulation, or sensory loss, foot ulcers may become a serious complication in up to 15 percent of all diabetic patients. Chronic diabetic foot ulcers (DFUs) need prolonged treatment and may even lead to amputation.
Researchers at the Centers for Disease Control and Prevention report that foot and leg amputations decreased dramatically between 1996 and 2008. Over those 12 years, amputations dropped from 11 out of every 1,000 diabetic adults to only four-a decrease of almost 64 percent. Over the same period, however, the number of people officially diagnosed with diabetes tripled.
