My blood sugar is 6.5 two hours after I eat, but it is 8.5 in the morning. Why?
Blood sugar levels often rise overnight due to the liver's increased glucose production, a phenomenon known as the dawn phenomenon, according to Dr. Rajiv Kovil, a Diabetes & Obesity Specialist. Many individuals, especially those with prediabetes and type 2 diabetes, experience higher fasting blood sugar levels in the morning compared to post-meal readings. Factors such as late dinners, carbohydrate-rich snacks, and inadequate physical activity can also contribute to elevated morning glucose levels.
