How to Treat Low Blood Sugar


Hypoglycemia (low blood sugar) must be treated immediately. Without treatment, a low blood sugar can be dangerous. All people with diabetes will experience low blood sugars, and symptoms can be different for different people.

Treatment should be given whenever the blood sugar drops below 70 mg/dl (3.9 mmol/l) or symptoms are present.

Hypoglycemia Symptoms and Treatment

If not better in 15 minutes, repeat treatment. If the next meal or snack is more than 30 minutes away, give an extra snack of carbohydrate and protein. For smaller kids, the amount may need to be adjusted, see here for more information.

If no response in 15 minutes, administer glucagon. If the next meal or snack is more than 30 minutes away, give an extra snack of carbohydrate and protein.
