When blood sugar levels are high, the kidneys overcompensate by causing you to urinate more often. During the night, these frequent trips to the bathroom lead to disrupted sleep. High blood sugar may also cause headaches, increased thirst, and tiredness that can interfere with falling asleep.
The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. It usually happens between 4 a.m. and 8 a.m. The cause of the dawn phenomenon isn't clear.
A person who takes insulin doesn't eat a regular bedtime snack, and the person's blood sugar level drops during the night. The person's body responds to the low blood sugar by releasing hormones that raise the blood sugar level. This may cause a high blood sugar level in the early morning.

Changes in blood sugar levels
In people with diabetes, the pancreas does not produce enough insulin, or the body does not use insulin effectively. This causes excess glucose in the blood. Fatigue and weakness may result when the cells do not get enough glucose.
Among diabetic, higher blood glucose, or hyperglycemia, has historically been associated with anger or sadness, while blood sugar dips, or hypoglycemia, has been associated with nervousness. Persons with diabetes are not the only ones vulnerable to mood disturbances as a result of blood sugar fluctuations.
