Diabetic Foot

The grounding supports a multifactorial aetiology rather than a single cause. Diabetic foot problems are caused by combinations of diabetic neuropathies, peripheral vascular diseases, and infection, with many diabetic foot infections beginning in a wound, often a neuropathic ulceration.

Loss of sensation and poor circulation are central to the disease process. These changes allow injuries to go unnoticed and impair healing, so wounds can become colonized and then infected, with progression to deeper ulceration, gangrene, and possible amputation.

Diabetes mellitus is the underlying condition associated with risk. The supplied material also supports neuropathic ulceration, poor circulation/peripheral vascular disease, and existing wounds as factors that predispose to infection and severe foot complications.

Management is described at the level of wound and infection care, vascular assessment, and prevention-oriented foot care. For diabetic foot infections, care is guided by infection severity classification and vascular assessment, with escalation to hospitalization, imaging, surgical intervention, or amputation when needed; multidisciplinary diabetic wound and amputation prevention clinics are also emphasized.
