Fasting blood glucose 14 means fasting blood glucose 14mmol/L. Fasting blood glucose 14mmol/L is high. In general, the normal range of fasting blood glucose is 3.9~6.1mmol/L, and the 2-hour postprandial blood glucose should be less than 7.8mmol/L. If the fasting blood glucose is ≥7.0mmol/L or the 2-hour postprandial blood glucose is ≥11.1mmol/L, the diagnostic standard of diabetes mellitus is reached. Therefore, a fasting blood glucose of 14 mmol/L is high. Fasting blood glucose 14mmol/L is not only an abnormal condition, but also a more serious one. If you do not seek medical attention in time to control your blood sugar, acute and chronic complications such as diabetic ketoacidosis, diabetic nephropathy, diabetic retinopathy, etc. may occur as your condition progresses. For fasting blood glucose 14mmol / L, it is recommended that patients seek timely consultation for targeted treatment.
