If blood glucose 6.1-6.9 mmol/L is measured during fasting, consider impaired fasting glucose regulation, which is mainly regulated by diet and exercise. If pregnant, consider gestational diabetes mellitus, which is treated with diet, exercise, and insulin. If blood glucose 6.1-6.9mmol/L is measured after meal, it is normal and no regulation is needed. Fasting blood glucose 6.1-6.9mmol/L is considered to be diagnosed with impaired fasting glucose regulation, which belongs to the pre-diabetic stage, and it is recommended to improve the oral glucose tolerance test, glycated hemoglobin and other related examinations, and should be adjusted as early as possible with diet and exercise, and control the weight, to avoid progression to diabetes mellitus. In case of pregnant women, fasting blood glucose 6.1-6.9mmol/L is consistent with the diagnosis of gestational diabetes mellitus, mainly through diet and exercise to control glucose, eating less and more meals, and at the same time pay attention to the intake of sufficient nutrition to ensure fetal development, and if necessary, applying insulin to regulate blood glucose. If the postprandial blood glucose is 6.1-6.9mmol/L, it is normal blood glucose and no special intervention is needed. If the blood glucose is between 6.1-6.9mmol/L, it is recommended to consult a doctor in time for treatment under the doctor’s guidance.
