What should normal blood glucose levels be?

Normal blood glucose levels are an important indicator of overall health. For fasting blood glucose (i.e., after at least 8 hours without eating), the normal range is typically defined as: - Fasting blood glucose: 3.9 millimoles per liter (70 milligrams per deciliter) to 6.1 millimoles per liter (110 milligrams per deciliter). - Blood glucose 2 hours after a meal: no more than 7.8 millimoles per liter (140 milligrams per deciliter). These values apply to individuals without diabetes. For people with diabetes, the target blood glucose range may differ and should be determined based on individual circumstances and medical advice. If you are concerned about your blood glucose levels, it is recommended to consult a healthcare professional.
