Why Is My Blood Sugar High in the Morning?
Morning blood sugar readings are often higher than expected
Many people with diabetes notice their fasting blood sugar is elevated first thing in the morning, even after not eating for 8+ hours. This is frustrating and confusing.
Common Causes
- •Dawn phenomenon - hormones released early morning raise glucose
- •Somogyi effect - overnight low triggers glucose release
- •Insufficient evening medication
- •Late-night snacking
- •Liver releasing stored glucose
What Our AI Detected
The dawn phenomenon affects 50-70% of people with Type 2 diabetes. Your liver releases glucose between 4-8 AM to prepare your body for waking. This is normal, but in diabetes, your body can't regulate this spike.
✓ Readings 20-30 mg/dL higher in morning is common
✓ This doesn't mean your diet failed
✓ Pattern tracking reveals if it's consistent
