The number of patients who come to our department for acupuncture treatment because of high blood sugar is not small, and the biochemical index of blood sugar turns to normal, accounting for about 50%. The main reasons why the treatment has not yet normalized are: 1) the treatment time is still short; 2) the loss of pancreatic islet function is serious; 3) the patient has discounted in the implementation of the diet, thus affecting the efficacy. Acupuncture for diabetes, unlike the treatment of fatty liver, simple obesity, hyperlipidemia, etc., requires very careful treatment, especially in the early stage of treatment, to avoid over-eating and to prevent hypoglycemia.
