As the incidence of diabetes increases, the complications of diabetes are becoming more and more frequent. The diabetic foot is one of the serious complications of diabetes, mainly due to peripheral neuropathy and peripheral vascular disease combined with excessive mechanical pressure, causing damage and deformity formation in the soft tissues of the foot and the bone and joint system, which in turn leads to a series of foot problems, ranging from mild neurological symptoms to severe ulcers, infections, vascular disease, Charcot arthropathy and neuropathic fractures. If aggressive treatment does not adequately address the symptoms and complications that arise in the lower extremities, the consequences can be catastrophic. Therefore, treatment of the diabetic foot is determined primarily by the condition of the foot. For early symptoms of diabetic lower extremity neuropathy, such as numbness and pain in the toes, the main treatment is to enhance nerve nutrition with blood glucose control up to standard. If the foot is at risk of ulceration it can be treated with modified shoes, molded inserts or deepened shoes, with patient education and regular follow-up. Once skin dehiscence occurs, aggressive intervention is necessary to prevent further progression of the injury. If ulcers have already appeared, early hospital consultation and treatment is required. For mild ulcers without obvious bone destruction, they can generally be treated with local drug changes in internal medicine, but if there are serious deep ulcers or bone destruction, they require debridement treatment by the customer, and in serious cases, surgical amputation may be required, or even life-threatening, etc. Therefore, the danger of diabetic foot is very serious and needs to be detected and treated as early as possible.
