Managing Low and High Blood Sugar

Avoid hypoglycemia and hyperglycemia by checking your blood glucose (blood sugar) regularly and knowing the symptoms of each.

Hypoglycemia (low blood sugar)

Hypoglycemia refers to low blood glucose levels which drop below 70 mg/dL when you are taking medications that can cause low blood glucose.  Significant hypoglycemia is considered below 54 mg/dL.  It's an acute complication of diabetes and may be seen in individuals who use insulin or specific kinds of oral diabetes medication.  If you use oral diabetes medications, ask your physician or diabetes educator whether hypoglycemia should be a concern for you.

Hyperglycemia (high blood sugar)

Hyperglycemia refers to chronically high blood glucose (blood sugar) levels in people living with diabetes. Most medical professionals define hyperglycemia by using the blood glucose goals that you and your physician have established and combining those goals with the blood glucose target ranges set by the American Diabetes Association. In general, it’s when your glucose is over 180 mg/dL consistently.
