Is it high glucose, low glucose, or diabetic ketoacidosis (DKA)?
When your child has diabetes, there’s a lot to learn every day. While high and low glucose levels can happen in day-to-day diabetes care, DKA is a serious diabetes condition6.
DKA can happen when the body doesn’t have enough insulin. Instead of using glucose for energy, the body breaks down fat and makes ketones. Ketones can build up in the blood and make it acidic, which can be dangerous at high levels6.
The information below can help you better understand what your child may be feeling and when to seek help.
High glucose7,8
Also called high blood sugar or hyperglycemia (at or above 180 mg/dL)
Common symptoms7
- High sugar levels in blood
- Urinating more than usual
- Feeling thirsty
Low glucose9
Also called low blood sugar or hypoglycemia (below 70 mg/dL)
Common symptoms9
- Feeling shaky
- Headache
- Nausea
- Hunger
DKA6
Also called diabetic ketoacidosis
Common symptoms6
- Blood sugar levels stay high
- High ketone levels found in urine or blood
- Fruity breath
- Vomiting
- Trouble breathing
- Dry or flushed skin
- Confusion
Continue to follow your child’s diabetes care plan. Call their doctor or get medical help if their symptoms are severe or don't improve.

How can I see my child’s glucose data?
With the LibreLinkUp app††, you can view your child’s glucose data remotely on your smartphone#§§. That means you can stay informed about their glucose levels—even when you’re not together.
LibreLinkUp†† allows you to:
- See current glucose information, trend arrow, and 12-hour historical graph
- Set your own alarm† notifications
- Receive alarms in real time#
† Alarm notifications will only be received when alarms settings are enabled and turned on and sensor is within 20 feet (FreeStyle Libre 2) or 33 feet (FreeStyle Libre 3) unobstructed of the reading device.

Can my child use Libre systems at school or daycare?
Yes. The Libre 3 Plus sensor stays on your child and tracks their glucose every minute of the day*—whether they’re at home, school, or daycare.
If your child has a compatible smartphone§§, they can check their glucose using the Libre app§§. You can view their glucose data remotely through the LibreLinkUp app†† and share# access with other caregivers or family members.
It may also be helpful to speak with your child’s school nurse or daycare provider ahead of time about their diabetes care plan—including how to recognize signs of low or high glucose levels and how to respond if needed.

When can my child use the Libre app on their own?
The Libre app§§ is approved for children 4 years and older. However, many children with diabetes—especially toddlers (2+ years2,3) and those who are newly diagnosed—are not ready to use the app on their own or may not have a smartphone§§ yet. In these cases, parents or caregivers typically use the Libre app§§ on their child’s behalf.
As your child grows, you can decide together when they’re ready to begin using the Libre app§§ independently. You can continue to view their glucose readings through the LibreLinkUp app††. Many teenagers—and some preteens—use the Libre app§§ on their own. Open communication between you and your child can help you determine when they’re ready to take on more responsibility.

How do alarms work with Libre systems?
Libre systems offer optional, customizable alarms† that notify you when your child’s glucose goes above or below your set levels. With the help of your child’s doctor, you can set personalized glucose alarms that alert you as soon as your child’s glucose is too low or too high.
If your child uses a compatible smartphone§§, alerts are delivered through the Libre app§§ so they can take action quickly. You can also receive notifications through the LibreLinkUp app††, helping you and other caregivers stay informed.
† Alarm notifications will only be received when alarms settings are enabled and turned on and sensor is within 20 feet (FreeStyle Libre 2) or 33 feet (FreeStyle Libre 3) unobstructed of the reading device.
