Low Blood Sugar

Hypoglycemia means that your blood sugar is too low. For most people, low blood sugar is less than 70.

What to watch for:

  • Headache
  • Fast heartbeat
  • Shaking
  • Sweating
  • Feeling tired
  • Weakness
  • Hunger
  • Feeling anxious

If you feel that you might have low blood sugar, check your blood sugar right away. If you can't check, treat your blood sugar to be safe.

What to do if your blood sugar is less than 70:

  1. Eat a high sugar food that does not have fat, such as one of these:
      • ½ cup of fruit juice
      • ½ can of regular soda
      • 3 or 4 hard candies (Lifesavers™, Jolly Ranchers™)
      • 1 small box of raisins
      • 1 tablespoon of sugar
      • 3 or 4 glucose tablets
  2. Wait 15 minutes and check you sugar again. If it is still below 80, have another serving of the sugar food.
  3. When your blood sugar is back to normal, you may still need to eat more. If it will be longer than 30 minutes until your next meal, eat a small snack. A glass of low fat milk or a piece of fruit is a good choice.


A low blood sugar can happen quickly. If not treated right away, low blood sugar can make you pass out. If you have type 1 diabetes, you may need a glucagon shot. Someone you live with should learn how to give this shot. If they are not able to give the shot, 9-1-1 should be called.
