What is the normal range of blood sugar for healthy individuals?
The normal blood sugar level for fasting individuals is generally between 3.9 and 6.1 mmol/L. If the fasting blood sugar exceeds 6.1 mmol/L, it is considered high, but this does not necessarily indicate diabetes. However, it is important to be vigilant and take preventive measures against diabetes, especially for those with potential risk factors. Regular physical examinations and attention to diet are crucial.
The normal range for fasting blood sugar is typically 3.9-6.1 mmol/L. Blood sugar levels between 6.1-7.0 mmol/L are considered high but do not constitute diabetes. Postprandial blood sugar after two hours should be 4.7-7.8 mmol/L. Additionally, fasting blood sugar reaching or exceeding 5.1 mmol/L during pregnancy is indicative of gestational diabetes.
High blood sugar does not necessarily mean diabetes. A fasting blood sugar level above 7.0 mmol/L and a random postprandial blood sugar level greater than 11.1 mmol/L can be diagnosed as diabetes. However, fasting blood sugar between 6.0-7.0 mmol/L and postprandial blood sugar between 7.8-11.1 mmol/L may indicate a risk of developing diabetes. It is essential to control diet promptly to prevent diabetes. Sometimes, eating before a test can also cause elevated blood sugar levels. The reference values for fasting and postprandial blood sugar are different. Only when the measured values exceed the reference range multiple times and the patient exhibits the "three polys and one less" symptoms can diabetes be diagnosed.
