Hyperglycemia or high blood glucose (sugar) means your blood glucose is over 180 mg/dl (10.0 mmol/L). Risk of high blood glucose goes up if you take too little diabetes medicine, eat more than usual or are less active. If your body does not make enough insulin or is not able to use the insulin you make well, too much glucose stays in your blood. Talk to your healthcare team about how you can lower and prevent high glucose.
