Hypoglycemia in Children

What are the signs and symptoms of hypoglycemia?

Pediatric hypoglycemia symptoms range from mild to severe, depending on the extent of the condition. They may include:

• Irritability
• Dizziness
• Headache
• Shakiness or clumsiness
• Hunger
• Pale skin
• Sweating
• Fast or irregular heart rate
• Confusion or difficulty paying attention
• Blurry vision
• Seizure
• Loss of consciousness

If your child experiences many episodes of hypoglycemia over time, they may stop getting symptoms. This is a condition called hypoglycemia unawareness. It happens when the body stops releasing adrenaline in response to low blood sugar. Adrenaline is the hormone that causes symptoms such as fast heart rate and sweating. Without adrenaline, there is no warning that your child needs to raise their blood sugar level. As it continues to drop, they will go into severe hypoglycemia, which requires emergency treatment.

How is pediatric hypoglycemia diagnosed?

Children and adolescents who monitor their blood sugar at home to manage diabetes often use a glucose meter. This is a portable machine that measures the glucose in their blood. This allows families to detect hypoglycemia at home. A typical blood sugar range is between 70 and 140 mg/dl (milligrams of glucose per deciliter of blood). However, your child's ideal range may vary depending on their age and condition. We will help you determine the best range for your child.

For children without diabetes, we may make a pediatric hypoglycemia diagnosis after a physical exam, medical history and blood test. We will check your child's blood sugar and may also test their insulin production. We will also see if we can relieve your child's symptoms by raising their glucose level. We may have your child undergo supervised fasting at the hospital, to safely monitor any changes in their glucose level.

How is hypoglycemia treated in children?

Pediatric hypoglycemia treatment depends on the cause and the seriousness of the condition.

In most mild cases, your child can bring their blood sugar level up by eating or drinking something sugary such as candy, juice or glucose tablets. They can then keep their blood sugar stable by eating regularly. They should get balanced nutrition that includes complex carbohydrates, fat and protein.

Children and adolescents with diabetes will also need to test their blood sugar often. They should learn to recognize the early symptoms of hypoglycemia so they can treat it quickly.

When hypoglycemia is severe, your child needs immediate medical treatment. They may need an injection of the hormone glucagon, which can bring their glucose levels up quickly. This is important if your child can't eat or drink because of a seizure or loss of consciousness. We may prescribe a glucagon kit to your family to keep on hand for such emergencies. If we hospitalize your child, we may provide glucose intravenously (through a tube into their vein) to keep them stable.

If hypoglycemia happens to your child often, we will try to determine why. Some families may need to improve their diabetes management. We may recommend changes to your child's diet or medicine, or work with your child to better manage their diabetes.

When your child has a different reason for their hypoglycemia, we will work with you to manage that problem. We may recommend changes to your child’s lifestyle or medicine, depending on their needs.
