Diabetic foot infection is any infection of the foot in a diabetic.[2] Symptoms may include pus from a wound, redness, swelling, pain, or warmth.[1] Foot ulcers; however, may occur without being infected.[1] Complications can include infection of the bone, tissue death, amputation, or sepsis.[2]

They most often form following a diabetic foot ulcer.[2][1] Bacteria that are commonly involved include staphylococcus, streptococci, pseudomonas, and gram-negative organism.[2] The underlying mechanism often involves poor blood flow and peripheral neuropathy.[2] Diagnosis is based on symptoms and maybe supported by deep tissue culture.[2][1]

Prevention includes wearing appropriate shoes.[2] Treatment involves proper would care and antibiotics.[2] The duration of antibiotics is often two to four weeks.[2] Hyperbaric oxygen therapy may also help.[2] They are common and occur equally frequently in males and females.[2] Older people are more commonly affected.[2]
