- Cortisol
- Growth hormone
- Epinephrine (adrenaline)
- Glucagon
These hormones signal the liver to release stored glucose into the bloodstream to offer energy for waking up. In people without diabetes, the pancreas responds by releasing more insulin to stablize blood sugar.
But in people with diabetes or insulin resistance, the body doesn’t produce enough insulin, or the insulin doesn’t work properly. As a result, blood sugar increases and stays elevated.
⚠️ Signs You Might Be Experiencing the Dawn Phenomenon
- High blood sugar levels only in the morning (fasting glucose)
- Normal or low blo0d sugar before bedtime
- Feeling sluggish, thirsty, or foggy-headed upon waking
- Dry mouth or headache in the morning
If your blood sugar increases before breakfast even after a light or carb-free dinner, the dawn phenomenon could be the reason.
