What is low blood sugar?
You may have briefly felt the effects of low blood sugar when you've gotten really hungry or exercised hard without eating enough. This happens to nearly everyone from time to time. It's easy to correct and usually nothing to worry about.

If you have a health problem that tends to cause low blood sugar, it's a good idea to teach your family, friends, and coworkers about what symptoms to watch for and what to do. You may also want to wear a medical alert bracelet or necklace.
