What is Diabetic Foot Ulcer?
A diabetic foot ulcer is an open sore or break in the skin that can affect people living with diabetes. It most commonly appears on the bottom of the foot and is estimated to occur in about 15% of patients with diabetes.
Risks increase for individuals who use insulin and for those with diabetes-related kidney, eye, or heart disease. Extra factors such as excess weight, smoking, and alcohol use may also contribute to the development of foot ulcers.
Diabetic Foot Ulcer
Risks
Higher risk with neuropathy, poor circulation, foot deformities (bunions/hammer toe), smoking, and uncontrolled blood sugar. Wearing inappropriate footwear can worsen the condition.
Causes
Long-standing diabetes can reduce or eliminate the ability to feel pain in the feet due to nerve damage. Ulcers can form without pain, so patients may not realize the problem early.
Wound Care
Prevent infection and promote healing by offloading pressure, removing dead tissue (debridement), applying the right medication or dressings, and managing blood glucose and other health issues.
