First of all, I can tell you for sure that the doctor didn't lie to you. Diabetes can cause the wounds on patients' feet to persist. There are two main reasons: ① hyperglycemia is the best culture medium for bacteria, and wounds on the skin of diabetic patients are more likely to cause bacterial reproduction, which directly leads to the aggravation of infection; ② Due to slow blood circulation and poor blood supply of lower limbs, effective anti-inflammatory drugs cannot be absorbed, which increases the difficulty of anti-infection treatment. These two points are the reasons why diabetic feet are not easy to heal after they are rotten. /span If the treatment is not timely or the development of the disease is not controlled, the wound will get bigger and bigger until the patient can only survive by amputation, so don't underestimate diabetic foot rot and be sure to treat it actively. In view of the particularity of this kind of diabetic wounds, the first task is to control blood sugar, and then it is suggested that local wounds should be treated with external application of traditional Chinese medicine, which has good clinical effect. /span
