Why am I high in the morning?
Dawn phenomenon, overnight patterns and why one morning number rarely tells the whole story.
The dawn phenomenon
Hormones rise in the early morning to help the body wake. That can signal the liver to release glucose, and people with diabetes may see a morning rise.
Other clues
A late meal, stress, illness, a pump-site problem or an insulin pattern that needs review may look similar.
- Compare bedtime, overnight and waking information when available.
- Check delivery equipment if the rise is sudden or unusual.
- Take repeated patterns—not a self-prescribed dose change—to your team.
Safety first
Use your own sick-day and ketone plan for persistent highs.
- Severe hypoglycaemia, loss of consciousness, trouble breathing, persistent vomiting, or suspected diabetic ketoacidosis can be life-threatening. Follow your emergency plan and seek urgent local medical care now.
