Undiagnosed severe sleep apnoea and diabetic foot ulceration – a case series based hypothesis: a hitherto under emphasized factor in failure to heal

Although great progress has been made in managing diabetic foot disease, it continues to carry significant morbidity and mortality. Obstructive sleep apnoea (OSA) and diabetes frequently coexist and recent studies suggest significant under‐recognition of OSA in those with diabetes. There are no current reports on the direct clinical impact of OSA on acute or chronic diabetic foot ulcer healing.
