A1C Goals for Type 1
If you have diabetes, you probably know that the A1C blood test reflects your average blood glucose level over the past two to three months. Now, a study of more than 10,000 children and adults suggests that most people with type 1 diabetes should aim for an A1C between 6.5 and 6.9 percent. Researchers followed participants for eight to 20 years and found that diabetes-related eye and kidney complications increased with A1C levels above 7 percent. Complication rates didn’t differ much between those with A1Cs of 6.5 to 6.9 percent and those whose A1Cs were less than 6.5 percent. However, the risk of severe low blood glucose (hypoglycemia) was greater for those with an A1C of less than 6.5 percent. Of course, it’s important to discuss your individual A1C goal with your doctor. The American Diabetes Association recommends an A1C of less than 7 percent for most people, and it’s not known if this study will change current guidelines.
