The 1-hour postprandial blood glucose is considered as random blood glucose, and a random blood glucose of 11.6 mmol/L is abnormal and is considered high blood glucose. In general, normal adults have a fasting blood glucose of 3.9-6.1 mmol/L, a 1-hour postprandial blood glucose of less than 11.1 mmol/L, and a 2-hour postprandial blood glucose of less than 7.8 mmol/L. Fasting blood glucose ≥7.0 mmol/L, or 2-hour postsugar load blood glucose ≥11.1 mmol/L, or random blood glucose ≥11.1 mmol/L, accompanied by the symptoms of three more and one less (drinking, eating, and urinating more, and weight loss) can be considered for the diagnosis of diabetes mellitus. A 1-hour postprandial blood glucose of 11.6 mmol/L is abnormal and is considered possibly diabetic. However, if only one blood glucose measurement is taken, diabetes cannot be diagnosed and further tests are needed to confirm the diagnosis. Once diagnosed with diabetes, you need to adjust your diet, increase exercise, pay attention to work and rest patterns, and follow the doctor’s instructions for treatment under the guidance of a doctor or dietitian. Therefore, patients with 1-hour postprandial blood glucose of 11.6 mmo/L should consult a doctor for further examination and treatment.
