Blood glucose of 7.3 mmol/L can be taken without glucose-lowering drugs for a while. If the patient is just diagnosed with diabetes, fasting blood sugar reaches 7.3mmol/L, the diagnosis of diabetes is slightly higher than the normal high value, but within 3-6 months it is recommended not to use hypoglycemic drugs, you can control blood sugar through diet and strengthen physical exercise. If the blood glucose is still high after 3-6 months, the use of glucose-lowering drugs should be considered. If blood glucose 7.3mmol/L is the blood glucose two hours after meal, it is not necessary to take medication because the blood glucose value two hours after meal ranges from 4.4-7.8mmol/L, so it belongs to the normal blood glucose range.
