How to Prevent Low Blood Sugar

Know the things that can make your blood sugar drop, such as fasting for tests, exercising, and sleeping. Low blood sugar may increase the risk of harm to yourself or others, such as when you are driving.

Preventing low blood sugar is not always possible, but you need to take steps to avoid it. Be sure to take your insulin as prescribed, watch your sugar intake, and use caution during and after exercising.

  • Space meals evenly throughout the day. Talk to your health care provider about a plan for healthy eating.
  • Keep a supply of healthy snacks on hand.
  • Take your diabetes medicine as directed by your health care provider.
  • Tell others about your diabetes.
  • Ask your health care team when you should call them and when to call 911. Keep a list of emergency numbers with you: Your health care provider’s name and phone number and your pharmacy’s phone number.
  • Carry a list of your medicines in your wallet or purse.
  • Check your blood sugar levels the way your health care team advises you. Keep a record and bring it with your meter to your health care provider. You should do this for future visits as well. Make sure to tell your health care provider if you have had high or low blood sugar levels.

Make sure to take steps to manage your diabetes and learn to spot low blood sugar so you can treat it quickly before it gets worse.

Remember, low blood sugar can be serious if not treated immediately.

You should have a medical ID with you at all times, which can offer important information to medical personnel if you are unable to speak. For example, the ID can state that you have diabetes and whether or not you use insulin, and include drug allergy information.
