Hypoglycemic Reaction (Child)

Blood sugar is also called glucose. It is used as energy by the body. Sometimes, blood sugar drops too low (hypoglycemia). This causes a hypoglycemic reaction. Signs of a hypoglycemic reaction may include:

• Being grouchy, jittery, or nervous

• Confusion

• Feeling very hungry or weak

• Sweating

• Anger or personality changes

• Having nightmares

• Fast heartbeat

• Feeling dizzy or sleepy

• Changes in vision

• In severe cases, the child may have a seizure or faint (lose consciousness)

Hypoglycemia may occur in healthy children who have not eaten for a while. Or it may occur if they have had persistent vomiting or diarrhea. Some children are more likely to have hypoglycemic reactions. These include children with a metabolic or digestive problem, a hormone deficiency, or diabetes. Taking diabetes medicine or alcohol by accident may also cause low blood sugar. Chemicals called salicylates can also cause hypoglycemia. They are found in many foods and medicines, such as aspirin.

Hypoglycemia is diagnosed in children by testing blood. Low blood sugar must be raised to prevent a serious problem. If your child's glucose can’t be raised with oral sugar, then your child may be given an IV (intravenous) sugar solution. Or they may get a shot (injection) of glucagon. This is a medicine that helps raise blood sugar levels. Your child’s blood may be tested again after they skip one or two meals. This is called a fasting test. If your child still has hypoglycemia, the healthcare provider will test for other causes.
