Common causes
- The dawn phenomenon: before you wake, your body releases hormones such as cortisol and growth hormone that raise blood sugar to give you energy for the day.
- Late-night carbs: a bowl of cereal at 11 p.m. shows up in the morning.
- Short or poor sleep (NHLBI).
- Medication timing for people with diabetes; only your doctor should adjust it.
What's normal?
A fasting level below 100 mg/dL is normal; 100-125 mg/dL is in the prediabetes range (MedlinePlus). See normal blood sugar levels.
