Why is my blood sugar high in the morning?
If your blood sugar is high in the morning but normal after meals, it's often because your liver releases extra glucose overnight.
This is called the dawn phenomenon and is influenced by hormones.
Other factors like late dinners, snacks, lack of exercise, poor sleep, and stress can also play a role.
To manage this, eat dinner earlier, choose healthier foods, stay active, and get enough sleep.
If your blood sugar stays high, talk to your doctor about adjusting your medication.
