diabetic foot ulcerDiabetic foot problems, including ulcerations, infections, and gangrene, are the most common grounds for hospitalization among diabetic patients. In particular, foot ulceration affects between 15 and 25 percent of patients with diabetes mellitus during their lifetime. 1Diabetic foot ulcers are notoriously difficult to heal, and may take weeks or months to close, even if treated promptly and intensively. Unfortunately, a significant number of diabetic foot ulcers may never heal satisfactorily, despite current best practice. Of those diabetic foot  patients who do ultimately achieve wound closure, it is thought that around 70 percent will have at least one further recurrent lesion within 5 years of treatment.1

The development of diabetic foot disease can be ascribed to three principal pathologies; diabetic peripheral neuropathy, peripheral arterial disease, and infection. These factors can present individually or in any combination, although neuropathy is considered to be the most important pathology.2 Diabetic neuropathy can affect the sensory, motor and autonomic functions, and increases the risk of ulceration seven-fold. The lack of pain and sensation in the foot caused by sensory neuropathy makes the foot highly vulnerable to repetitive trauma, which may go unnoticed until ulceration becomes visible. At this stage, treatment is more problematic.

It is not difficult to see why diabetic ulcers are one of the most feared complications of diabetes.2 More than 1 million people with diabetes require amputation each year, leading to significant morbidity, mortality, and obvious psychological trauma. The healthcare costs of performing a large number of amputations with all the aftercare that is required is also substantial.3,4 It is therefore essential that steps are taken to reduce the risk of a diabetic foot ulcer forming. Next week we will look at some of the preventative measures available to both patients and healthcare providers to help avoid the crisis of a diabetic foot ulcer.
