Pediatric Hyperglycemia (High Blood Sugar)

Hyperglycemia, or high blood sugar, occurs when the blood glucose is above 250 mg/dl. 

What is Pediatric Hyperglycemia (High Blood Sugar)?

Hyperglycemia, or high blood glucose, means the blood glucose level is above target. It can be caused by too much food, not enough insulin, less activity than usual, stress or illness. Sometimes children outgrow their insulin dosage and have high glucose values. Be sure to discuss this with your child’s endocrinologist and/or pediatrician. 

Call 911 if the patient is unconscious or having a seizure followed by instructions given by your endocrinologist or primary care provider.

Normal glucose levels:

  • Before a meal: 80 – 130
  • 2 hours after a meal: less than 160

Helpful hints

  • Do not give extra insulin, such as mid-morning, mid-afternoon or during the night unless told to do so by the diabetes team or your provider. This can cause "stacking of insulin", resulting in low blood sugar or glucose.
  • When you notice a pattern of high blood glucose values, send your child's glucose log to the diabetes team.
  • High blood sugar does not mean that you are doing something wrong. It is information that can be used to improve your child's diabetes control.
