Actually a fasting blood sugar test is done when you havenât eaten anything for at least 8 to 10 hours. And yet I am inclined to say that even after 7 hours of fasting if your blood glucose is 111 mg/dl, you need to take it as a warning sign and start making changes to your lifestyle. To be sure, Iâd advise you to take a fasting blood sugar test for 3â4 consecutive test. If all the readings are above 100, it means that you are very likely prediabetic.
