Prevent Low Blood Sugar

Talk to your doctor, pharmacist or diabetes educator to learn how you can prevent low blood sugar.

There are many ways to prevent low blood sugar.

Talk to your doctor, pharmacist or diabetes educator to learn:

  • the best amount of diabetes medicine for you.
  • how to time your diabetes medicine with your food.
  • when your diabetes medicine is working the hardest.
  • how often to check your blood sugar.
  • how much exercise lowers your blood sugar.
    • Note: If you take insulin or a medicine from the Secretagogue class of medicines, check your blood sugar before you exercise. If your blood sugar is less than 5.5 mmol/L, have a snack that contains protein and a slow acting carbohydrate (such as a slice of whole grain bread with peanut butter). Slow acting carbohydrate slowly raises your blood sugar to prevent an episode of low blood sugar.
  • how to know the signs of low blood sugar.
    • Carry a fast acting carbohydrate with you at all times just in case you need it. Fast acting carbohydrate raises your blood sugar quickly.
