What Is Morning High Blood Sugar?
Morning high blood sugar refers to elevated glucose levels that occur shortly after waking up.
Many people searching for morning blood sugar spike notice that their blood sugar is significantly higher at 6 AM or 7 AM than it was before bedtime.

To provide this energy, the liver releases stored glucose into the bloodstream.
Normally, insulin keeps blood sugar levels balanced.
However, people with diabetes may not produce enough insulin or may experience insulin resistance.
As a result, glucose builds up in the blood and causes a fasting blood sugar high reading in the morning.

Between approximately 4 AM and 8 AM, the body releases hormones including:
- Cortisol
- Growth Hormone

- Adrenaline

For people without diabetes, insulin quickly compensates.
For people with insulin resistance, blood sugar rises significantly.
