For some people, a blood sugar below 90 mg/dL can make them feel like this. For others, it takes a lower blood sugar to cause these symptoms.

What Is Low Blood Sugar

A blood sugar level less than 70mg/dl is considered as low, or in other terms, hypoglycemia.

As glucose is stored as glycogen in the muscles and liver, it can be released into the blood during low blood sugar levels. Despite our bodys steady requirements of glucose, it is stored in very small quantities for consumption during sleep, strenuous exercise, or prolonged fasting periods.

Our brain requires glucose as its primary source of fuel but can utilize ketone bodies when its glucose reserves are depleted. The liver can produce ketone bodies from fats which the brain can utilize during limited glucose reserves or hypoglycemia.

How Is Hypoglycemia Treated In A Child

Treatment will depend on your childs symptoms, age, and general health. It will also depend on how severe the condition is.

For children with diabetes, the goal of treatment is to maintain a safe blood glucose level. This is done by:

  • Testing blood glucose often

  • Learning to recognize symptoms

  • Treating the condition quickly

  • Orange juice

  • Cake icing
