The global incidence of diabetes is increasing year by year, and the number of people with diabetic foot is gradually increasing, as is the prevalence of foot ulcers and amputations, with 13% of people with type 2 diabetes having risk factors for diabetic foot. In developed countries, about 1-2% of diabetic patients suffer from acute foot ulcers and 1 in 20 have a history of ulcers. In our country, such statistics are scarce and it is estimated that the prevalence may be higher. Diabetic foot disease causes tremendous pain to the patients themselves and a heavy economic burden to the family and society. The whole society should enhance the awareness of diabetic foot disease, improve the level of prevention and treatment, assess the risk of foot disease, detect and screen patients with diabetic foot disease at an early stage, and treat them aggressively to prevent foot ulcers and amputations. Identification of high-risk diabetic foot does not require expensive equipment, but only a careful clinical examination of the foot, and all diabetologists should remember the words of Dr. Paul Brand, “Take off your shoes and socks and examine your feet every time you see a diabetic patient.”
