Goals for Blood Glucose Control

Discuss blood glucose (sugar) targets with your healthcare team when creating your diabetes management plan.

People who have diabetes should be testing their blood glucose regularly at home. Regular blood glucose testing helps you determine how well your diabetes management program of meal planning, exercising and medication (if necessary) is doing to keep your blood glucose as close to normal as possible.

The results of the nationwide Diabetes Control and Complications Trial (DCCT) show that the closer you keep your blood glucose to normal, the more likely you are to prevent diabetes complications such as eye disease, nerve damage, and other problems. For some people, other medical conditions, age, or other issues may cause your physician to establish somewhat higher blood glucose targets for you.

The following chart outlines the usual blood glucose ranges for a person who does and does not have diabetes. Use this as a guide to work with your physician and your healthcare team to determine what your target goals should be, and to develop a program of regular blood glucose monitoring to manage your condition.
