Dr. G breaks down the epidemiology of diabetic foot disease, explaining who is affected, where it occurs, and why. He highlights key global figures — over 500 million people with diabetes and up to 25% developing a foot ulcer — to show this is a widespread, preventable problem.

Important facts: ulcers frequently recur (up to 40% within one year), most amputations (about 85%) are preceded by a foot ulcer, and outcomes vary widely by healthcare access and region.

Prevention is possible with routine foot screening, patient education, proper footwear, glycemic control, early treatment, and multidisciplinary care; future tools like AI and wearable sensors aim to shift care from reactive to predictive.
