Whether a blood glucose value of 6.7 mmol/L returns to normal should be determined on a case-by-case basis. If it is fasting blood glucose 6.7 mmol/L, it indicates elevated blood glucose, but elevated fasting blood glucose alone is not a definitive diagnosis of diabetes and should be combined with the presence of clinical symptoms of excessive drinking, eating, urination, and weight loss to make a joint diagnosis of diabetes.
Blood sugar of 6.7 mmol/L is not a serious condition even if it is fasting blood sugar, and it can be normalized. It is recommended to first pay attention to the diabetic diet, which includes adjusting the diet, avoiding overeating, reducing sugar and starchy foods (such as buns, steamed buns, noodles, thin rice, etc.), increasing exercise, and doing more aerobic ventilator outdoor activities. You should also keep good sleep, regular rest and avoid excessive mental stress. And closely detect the change of blood sugar and check glycated hemoglobin regularly. If there is a gradual increase or deterioration of blood glucose during treatment, prompt hospital consultation and choose the appropriate medication or insulin for symptomatic treatment.
If the postprandial blood glucose is 6.7 mmol/L, the level of glucose secretion is normal and there is nothing to worry about.
