Diabetes has many complications, and once detected, the complications of diabetes cannot be completely cured. Diabetic foot is a relatively serious complication of diabetes. Diabetic foot generally involves many years of underlying vascular and nerve damage that eventually leads to infection or ulceration, resulting in the final formation of diabetic foot. Whether such a serious complication can be cured actually depends on the duration of the patient’s condition, the extent of the lesion, and most importantly, how soon they seek medical attention. For instance, if the infection is very severe, has damaged the bone, or if there is dry gangrene with local tissue necrosis in the foot, then no matter what conservative treatment is applied, it will not be effective, and surgical amputation will be the only option, meaning the foot cannot be saved. However, if some individuals only have early-stage skin ulceration that cannot heal, or if there is an infection that is not very severe, and they seek medical attention early, controlling the infection and treating with nerve nutrition and vascular protection can actually heal the ulcerated area of the foot.
