Thank you for your query,
Hypoglycemia is not a common in children in healthy children.
It should be evaluated for any hormonal imbalance and rare disorders of glycogen storage disorders.
and prolonged starvation may cause hypoglycemia, but recurrent hypoglycemia
has to be evaluated further for any hormonal, storage, and for other reasons.
Give him a high carbohydrate
diet and keep chocolate or sugar available with the child.
So consult your Pediatrician
as early as possible for evaluation.
Hope I have answered your query.
