Ever wake up with high blood sugar even though you haven’t eaten for 8, 10, or even 12 hours?

It can feel confusing: if no food went in, where did the glucose come from?

In this video, we break down the science behind morning blood sugar, including the dawn phenomenon, the role of your liver, and the hormones that can raise glucose while you sleep and as your body prepares to wake up.

You’ll learn why fasting blood sugar can sometimes be higher than expected, what may be happening inside your body overnight, and why a high morning reading doesn’t always mean you ate something “wrong” the night before.

If you’re trying to better understand insulin resistance, diabetes, prediabetes, or your morning glucose readings, this video will help make the physiology much easier to understand.

In this video:
• Why blood sugar can rise while you’re fasting
• What the dawn phenomenon is
• Why your liver releases glucose overnight
• How cortisol and other hormones affect morning glucose
• Why your morning number may be higher than your bedtime number
