To perform treatment for diabetes, you should be seen in the endocrinology and diabetes department. Diabetes is caused by insufficient insulin secretion in the body and is also affected by the pituitary gland, so it belongs to the endocrinology department. Receiving treatment requires routine blood tests and, if necessary, oral glucose tolerance tests and insulin release tests, which can aid in the diagnosis. After having diabetes, fasting blood sugar is usually higher than 6.1 mmol/L, and medication is required for treatment. Specific medications include gliclazide, acarbose, etc. You can also choose local insulin injection for treatment, which has relatively stable effect. After treatment, patients need to regularly review their blood sugar to avoid blood sugar fluctuations otherwise it will easily affect the efficacy and also increase the risk of diabetic ketoacidosis.
