Control blood sugar: long-term poor blood sugar control may lead to diabetic foot, should follow the doctor’s advice to take metformin, acarbose and other hypoglycemic drugs or insulin injection treatment, with diet control, appropriate exercise and other ways to maintain blood sugar stability. 2. Infection control: broad-spectrum antibiotics or antibiotics selected according to the results of drug sensitivity test, such as clindamycin, amoxicillin, etc., can be used when maggots and bacterial infections are combined. 3. Cleansing: necrotic tissue can be removed by cleansing to reduce the chance of infection, and drainage is also needed when necessary. 4. Surgical treatment: for wounds with a large amount of necrotic tissue remaining, wounds that cannot be healed by medication, etc., surgical debridement can be carried out; amputation can be considered in case of extensive limb infection or even life-threatening infection. It is recommended to go to the hospital when maggots appear in diabetic foot and cooperate with the doctor for active treatment.
