What causes diabetic foot infections?

Multi-factorial: Diabetics often develop nerve damage, which can decrease sensation especially over the lower extremities. Ulcers can then develop on the feet, usually on pressure points from standing or a tight-fitting shoe. Diabetics may also have poor circulation, which can lead to breakdown of tissue and impaired healing of the ulcer, and high blood sugar allows bacteria to grow and cause infection.

Trauma etc: Decreased circulation, stepping on something, friction, ill-fitting shoes..Un controlled diabetes.

Multiple factors: Any open wound/ulcer has a chance for infection. Most wounds are colonized from day one with normal body flora. It's when the number of bacteria reach a critical level that infection occurs. Daily local wound care is important to help keep the number of bacteria in your wound low enough to allow for healing to occur.

Various factors: Diabetic patients often times will have poor circulation and a diminished healing ability which makes them more susceptible to developing foot infections. The presence of neuropathy is also a main contributor to the development of ulceration. If not treated promptly and appropriately, the foot ulcer can become infected, .

Good habits. : Diabetics should get into the habit of checking their feet daily for changes. Keep them moisturized with good lotion rather than soaking (which can dry your feet out more, cause cracking and chapping), wear supportive, protective shoes at all times, and above all, keep strict control of your blood sugar. Controlling your blood sugar keeps your nerves healthy, and avoids ulcers and infections.
