Diabetes normal range

In the diagnostic criteria of diabetes, the normal range of fasting blood glucose should be between 3.9-6.1mmol/L, and the 2-hour postprandial blood glucose should be less than 7.8mmol/L.

Under fasting conditions, the blood glucose level in the body is relatively stable. The range of 3.9-6.1mmol/L is determined through a large number of studies and clinical practice. If the fasting blood glucose is lower than 3.9mmol/L, hypoglycemia symptoms may occur, such as dizziness, fatigue, palpitation, etc., which can be life-threatening in severe cases. When the fasting blood glucose is higher than 6.1mmol/L, it may indicate that there may be abnormal glucose metabolism, but it cannot be diagnosed as diabetes only by one measurement result. Further examination and evaluation are needed, such as oral glucose tolerance test.

After a meal, blood glucose will gradually increase with the digestion and absorption of food, and then gradually return to normal under the regulation of the body. Generally, blood glucose less than 7.8mmol/L 2 hours after a meal is considered normal. If the blood glucose level is between 7.8-11.1mmol/L 2 hours after a meal, it is called impaired glucose tolerance. This is a manifestation of prediabetes. It is necessary to pay attention to it. By adjusting lifestyle such as reasonable diet and moderate exercise, it is possible to delay or prevent the development of diabetes. If the blood glucose level exceeds 11.1mmol/L 2 hours after a meal, it is highly suggestive of diabetes. It is necessary to further confirm the diagnosis in combination with clinical symptoms and other tests. It

should be noted that the normal range of blood glucose may vary slightly due to factors such as test methods, laboratory standards, etc., but the overall difference is not significant. In addition, for the diagnosis of diabetes, it is necessary to combine the symptoms, medical history, family history, etc. If you suspect diabetes-related problems, consult a professional doctor in time to obtain accurate diagnosis and reasonable treatment advice.
