what should my blood sugar be in the morning

Your blood sugar level in the morning before eating (fasting) should typically be between 4.0 to 7.0 millimoles per liter (mmol/L), which is about 70 to 99 milligrams per deciliter (mg/dL). This range is considered normal for healthy adults after an overnight fast. Levels slightly lower or higher may occur due to factors like sleep, stress, or the effects of the "dawn phenomenon," where blood sugar naturally rises in the early morning. If your fasting blood sugar consistently falls outside this range, consulting a healthcare professional is advisable for personalized recommendations and management.
