A fasting value of 6.2 mmol/L is generally normal for type 2 diabetes. The normal fasting blood glucose control target values for patients with type 2 diabetes are between 4.4 and 7.0 mmol/L, and the two-hour postprandial blood glucose value should be less than 10 mmol/L. So it is normal for patients to have a fasting of 6.2 mmol/l. Patients with diabetes should be careful not to eat sugary foods in their daily life, and they can do appropriate sports to enhance their immunity, as well as maintain sufficient sleep and measure their blood glucose regularly. Patients with type 2 diabetes need to monitor their blood glucose regularly, go to the hospital regularly for follow-up, and actively cooperate with the doctor for standardized treatment.
