Is it normal for blood sugar to rise at night?
Blood sugar levels surge while you’re sleeping, usually around 4 to 8 a.m. for someone with a normal sleep schedule. (It’s called the dawn effect.) In a healthy person, insulin can handle the surge by telling muscle, fat, and liver cells to absorb the glucose from the blood, which keeps your levels stable.
What is normal blood sugar before bed?
Your blood sugar goal at bedtime should be in the range of 90 to 150 milligrams per deciliter (mg/dL).

In the early hours of the morning, hormones, including cortisol and growth hormone, signal the liver to boost the production of glucose, which provides energy that helps you wake up. This triggers beta cells in the pancreas to release insulin in order to keep blood glucose levels in check.
What happens if blood sugar gets too high while sleeping?
