Keeping your blood sugar in a target range reduces your risk of problems such as diabetic eye disease (retinopathy),
kidney disease (nephropathy), and nerve disease (neuropathy).
The American Diabetes Association (ADA) suggests the following A1c and blood glucose ranges as a general guide. Children, people who have severe complications from diabetes, and people who have trouble recognizing the symptoms of low blood sugar may need a different target range. Work with your doctor to set your own
target blood sugar range. This will help you achieve the best control possible
without having a high risk of hypoglycemia.1, 2
