The length of time a diabetic foot patient can live after treatment is mainly related to the severity of the patient’s diabetic foot. If the diabetic foot is relatively mild, such as only ulcer formation, no infection or gangrene formation, then the effect of diabetic foot treatment is relatively good and will not have much impact on the overall life expectancy of the patient. On the contrary, if the diabetic foot disease is very serious and there is already local or total foot gangrene, and surgical treatment has been performed, if the surgical treatment is more effective, the patient will have no problem living for at least five years. If the patient is heavily infected, the effect after surgical amputation is not good, and the local wound does not heal, the patient is estimated to live about 1-2 years in this case.
