The tip of the iceberg: an overview of diabetic foot disease.

Diabetic foot disease is the leading cause of lower-extremity amputation globally and imposes a significant burden for healthcare services and patients alike. The main pathology is ulceration, due to neuropathy or peripheral arterial disease. The most frequent sign is ulceration on the foot. Ulceration needs to be referred to the multidisciplinary diabetic foot team promptly for a comprehensive management plan to be developed. Delay in referral is associated with poor outcomes. Management of diabetic foot ulceration is multifaceted, including offloading, revascularisation, infection control, debridement, glycaemic control and wound care. Management plans need to be patient focused and developed collaboratively across primary and secondary care settings. [ABSTRACT FROM AUTHOR]
