| Foot ulcers in diabetes require multidisciplinary assessment, usually by diabetes specialists and [[surgeon]]s. Treatment consists of appropriate bandages, [[antibiotic]]s (against [[staphylococcus]], [[streptococcus]] and [[anaerobe]] strains), [[debridement]] and arterial revascularisation. It is often 500 mg to 1000 mg of [[flucloxacillin]], 1 g of [[amoxicillin]] and also [[metronidazole]] to tackle the putrid smelling bacteria. Specialists are investigating the role of [[nitric oxide]] in diabetic wound healing. Nitric oxide is a powerful vasodilator, which helps to bring nutrients to the oxygen deficient wound beds. Specialists are using forms of [[light therapy]] such as LLLT to treat diabetic ulcers.

| Foot ulcers can be prevented by is by frequent physical examinations, good foot hygiene, [[diabetic sock]]s and shoes, and by avoiding injury.

| * Footwear; all major reviews recommend special footwear for patients with a prior ulcer or with foot deformities. One review added neuropathy as an indication for special footwear. The comparison of custom shoes versus well-chosen and well-fitted athletic shoes is not clear.

| ''Clinical Evidence'' reviewed the topic and concluded "Individuals with significant foot deformities should be considered for referral and assessment for customized shoes that can accommodate the altered foot anatomy. In the absence of significant deformities, high quality well fitting non-prescription footwear seems to be a reasonable option" <ref name="pmid16620415">{{cite journal |author=Hunt D |title=Foot ulcers and amputations in diabetes |journal=Clin Evid |volume= |issue= |pages=455-62 |year= |pmid=16620415 |url = http://clinicalevidence.com/ceweb/conditions/dia/0602/0602_I5.jsp | based on September 2005 search}}</ref>.
