How will I know if my blood glucose is too low (hypoglycemia)?

If your blood glucose goes low, you may feel shaky, dizzy, sweaty, weak, hungry or grumpy.

If your blood glucose is 70 mg/dL or below, treat your low blood glucose with 15 g of carbohydrates, such as:

  • Four glucose tablets
  • One serving of glucose gel
  • One half cup of regular fruit juice
  • One tablespoon of sugar or honey

After 15 minutes, check your blood glucose again. If it’s still below 70 mg/dL, repeat your treatment with another 15g of carbohydrates.

Repeat these steps until your blood glucose is at least 70 mg/dL.

To prevent your blood glucose from dropping again, eat a meal or snack every three hours. (24)
