Fasting blood glucose 6.7 is not normal, higher than the normal range, need to consult a doctor in time to clarify the cause of elevated fasting blood glucose, according to the doctor’s instructions for treatment. According to clinical data, the normal fasting blood glucose value should be 3.9~6.1mmol/L. When the fasting blood glucose is greater than or equal to 6.1mmol/L but less than 7.0mmol/L and the 2-hour post glycemic load blood glucose is less than 7.8mmol/L, it suggests that the fasting blood glucose is impaired. Impaired fasting glucose is a transition from the normal stage to diabetes, so it must be taken seriously and can be treated with dietary control or exercise. If it is clear that the fasting blood sugar is impaired, it needs to be controlled as soon as possible, and it is recommended to receive treatment under the guidance of a doctor, otherwise it may be transformed into diabetes, so the discovery of impaired fasting blood glucose should be timely to find a regular hospital treatment.
