Diabetic foot ulcers are caused by complications of diabetes on the nerve and / or blood vessels. Nerve damage from diabetes causes loss of sensation in the feet. This condition is known as peripheral neuropathy. The nerves that carry pain sensations normally to the brain of the foot is not functioning properly. Diabetics can suffer injuries due to stepping on something, wearing tight shoes, or stumble without knowing it until days or weeks.
Prevention of diabetic foot ulcers
Diabetic foot ulcers can vary from a kind of shallow red crater that involves only the skin surface to very deep and broad that involve tendons, bones and other deep structures. In advanced stages, ulcers can develop into an abscess (pus pocket), spreading infection of the skin and underlying fat (cellulitis), bone infection (osteomyelitis) or gangrene. Gangrene is dark and dead tissue caused by poor blood flow.
