If the blood sugar is within the normal range through diet control, it is usually possible not to take medication under the doctor’s guidance, but if the blood sugar still cannot be controlled well through diet control, it is necessary to follow the doctor’s instructions to use medication. The treatments for hyperglycemia include dietary control, appropriate exercise, and medication. For patients with mildly elevated hyperglycemia, they can control their blood glucose through dietary control and appropriate physical exercise, etc. If the above mentioned methods can maintain the stability of blood glucose, medication is generally not needed. If diet and exercise are not enough to control blood sugar, patients with high blood sugar need to be treated with hypoglycemic drugs, including oral hypoglycemic drugs such as metformin or insulin injections. Patients with high blood sugar should actively cooperate with doctors for treatment, and it is recommended to go to the hospital if the blood sugar control is not good.
