It's very important for your child's blood sugar to not get too low. Very low blood sugar (hypoglycemia) can affect a child's developing brain. So manage your child's blood sugar as much as possible without letting it get too low. Children can't always tell you when they have low blood sugar. Over time, you will learn what is normal for your child. This will help you recognize symptoms of low blood sugar. Pay close attention to how your child is acting. Your child may have low blood sugar if they are:
- Too hungry
- Pale
- Grumpy or irritable
- Sweaty
- Sleepy or drowsy (lethargic)
- Staring into space or glassy-eyed
- Shaky
- Confused or having trouble concentrating
- Complaining of vision problems, headaches, or nightmares
- Uncoordinated
- Dizzy
If you suspect your child has low blood sugar, check it right away. If the result is less than 70 mg/dL, or another number your child's doctor has advised, take action. Treat your child right away with a fast-acting sugar as you were told by the doctor. Check your child's blood sugar again in 15 minutes to be sure it's no longer low. If it's still low, give your child more of the fast-acting sugar. If your child is confused, unresponsive, unconscious, or having convulsions (seizures), they may have severely low blood sugar. Treat your child right away with injectable glucagon. This is a substance that raises your child's blood sugar very quickly. Always have an emergency kit with a shot of glucagon with you. (Your child's doctor will teach you how to give a glucagon shot.) Ask your child's doctor about nasal glucagon. It is approved for children 4 years and older.
