Why do blood glucose levels vary from day to day even when the same amount of insulin is taken?
The level of glucose in your blood depends on a lot of different factors. For instance, the amount and kind of food you eat, your activity and stress levels, and whether or not you are sick can affect your blood glucose levels. Even the time of day you perform the test can affect your reading. The important thing is to try to achieve your target blood glucose levels. You’ll want to check your blood glucose regularly so you can determine if your diabetes-care plan is managing your diabetes.
