What is the blood sugar number? Is it ok for my blood sugar to go up and down? Why is your blood sugar level high in the morning?
A “blood sugar number” is the concentration of glucose in your blood. Glucose is used as a fuel by the cells of the body. Everyone has glucose circulating in their blood. It is normal for the levels to go up and down, but in people without diabetes, the levels stay in a fairly narrow range. People with type 2 diabetes tend to have higher blood glucose levels in the morning. This is because insulin doesn’t work as well as it should and the production of glucose in the liver, which is normal during a time of fasting (overnight), is increased.
