Topic Overview

Review the symptoms of low blood sugar if you have diabetes or some other health condition that can cause low blood sugar. Know the early symptoms. You may not always have the same symptoms.

  • Check your blood sugar if you think it may be low.
  • Eat 15 g of carbohydrate, preferably as glucose or sucrose tablets or solution, or from quick-sugar foods. Liquids will raise your blood sugar faster than solid foods.
  • Wait 15 minutes after taking glucose or sucrose tablets or solution or eating a quick-sugar food. If your blood sugar is still below 4.0 mmol/L, eat another quick-sugar food.
  • If your blood sugar continues to be below 4.0 mmol/L or you are getting more sleepy and less alert, call 911 or other emergency services immediately. If possible, have someone stay with you until your blood sugar is above 4.0 mmol/L or until emergency help arrives.
  • When your blood sugar is above 4.0 mmol/L, eat a regular meal or a snack (such as a peanut butter sandwich). Do not take your insulin or other diabetes medicine until your blood sugar is back to normal.
