The Ups and Downs of Blood Glucose

Here's what a day of blood glucose readings might look like


Here's what a day of blood glucose readings might look like for someone with no diabetes, a person with type 1 (with an A1C of about 8 percent), and a person with type 2 taking oral medication (also with an A1C around 8 percent). While these hypothetical examples show typical patterns, diabetes is different for everyone. Your day-to-day readings may vary considerably—and your target A1C is most likely lower.

In the chart below, you can see that a person without diabetes stays within a fairly narrow band (indicated in yellow), ranging from about 70 to 130 mg/dl. The person with type 1 diabetes, on the other hand, oscillates widely between low and high depending on insulin and food intake. And the type 2 profile, which is based on someone who takes oral medication and not insulin, shows fewer ups and downs, but is generally in a range much higher than that of a person with no diabetes.
