Ideal Blood Sugar Targets For Most Adults | Cornerstones4Care®

Blood Sugar Targets for Most Adults

The American Diabetes Association (ADA) recommends that A1C be below 7% for most adults (pediatric targets are different). Lowering A1C to below 7% may help reduce the risk of some diabetes-related health problems. The American College of Clinical Endocrinologists (AACE) recommends that people with diabetes aim for an even lower A1C goal of below 6.5%. However, A1C goals are somewhat different for everybody. The doctor will set targets for you or the person with type 1 diabetes you care for, based on age and other individual factors. 

Remember that it’s almost impossible to keep your blood sugar at an ideal level all the time. From time to time, almost everyone with type 1 diabetes will experience either high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia). Reviewing your blood sugar readings with your diabetes care team can help you to identify things that can cause your blood sugar to go too high or too low and help you to make the changes you need to stay on track. 

Blood sugar recommendations

In addition to A1C goals, the ADA and AACE also have day-to-day blood sugar recommendations for adults with diabetes that are shown in the chart below.




A1C Less than 7% Less than 6.5%
Before a meal
 (preprandial plasma glucose [sugar])       
80 to 130 mg/dL  Less than 100 mg/dL 
After a meal
 (postprandial plasma glucose [sugar])         
 Less than 180 mg/dL   Less than 140 mg/dL 


Remember that blood sugar goals can be different from person to person. For example, if you can achieve an A1C of less than 6.5% without risking low blood sugar (hypoglycemia), your health care provider might recommend trying to do so. However, for someone with a history of dangerously low blood sugar, a goal of less than 8% might be safer and more practical.

Do You Go Too Low?

Severe low blood sugar, also known as hypoglycemia, can be very serious when not detected and treated immediately. Learn how to tell if your blood sugar is running low, and what to do about it.
