Is a blood glucose level of 6.6 mmol/L two hours after a meal normal?

Blood glucose level of 6.6 mmol/L three hours after a meal is usually considered abnormal.

Under normal circumstances, blood glucose levels should return to fasting levels three hours after eating. For the general population, the normal fasting blood glucose range is 3.9–6.1 mmol/L. For pregnant women, fasting blood glucose should not exceed 5.1 mmol/L. A value of 6.6 mmol/L three hours after a meal exceeds the normal range and is therefore considered abnormal. It is recommended to repeat the blood glucose test. If two consecutive measurements are above the normal range, a diagnosis of diabetes may be made.

After a confirmed diagnosis of diabetes, it is recommended to follow medical guidance for pharmacological treatment. For example, medications such as metformin or glimepiride may be prescribed to reduce hepatic glucose output, stimulate insulin secretion, increase insulin levels in the body, and lower elevated blood glucose. In cases of significantly high blood glucose, insulin therapy with agents such as insulin aspart or insulin detemir may be used under medical supervision to improve glucose metabolism and reduce hyperglycemia.
