Hyperglycemia (high blood sugar) is when your blood sugar levels are above the recommended target range. If you often have hyperglycemia, it can increase your risk for diabetes-related complications to your organs, including your eyes, heart, kidneys, and nerves.
But you can manage and prevent hyperglycemia with some simple steps!
Target Blood Sugar Ranges
The American Diabetes Association (ADA) recommends the following blood sugar ranges:
Time of Day
Target Blood Sugar Range
Fasting (upon waking and before eating)
80 to 130 mg/dL
Before a meal
80 to 130 mg/dL
Two hours after a meal
80 to 180 mg/dL
Some recommendations may vary depending on your personal needs, but if your blood sugar rises above these ranges, you may be experiencing hyperglycemia. Talk to your healthcare team about the right levels for you.
