My 2.5 year old nephew was diagnosed with Type 1 diabetes two weeks ago. His mother is interested in knowing whether the fluctuations in blood sugar level are affecting his behavior. He seems to be more negative and, almost hyperactive, at times. Do blood sugar levels affect the behavior of toddlers? How do they feel when the level is low or high?


Yes, abnormal blood sugar levels can affect mood and behavior in toddlers. Low blood sugar can cause the child to either become more quiet, or more cranky than usual. Many parents report that their children become moody with a high blood sugar. Children can also have mood swings unrelated to blood sugar level.

It is best to check the blood sugar frequently to see what the correlation there is if any between blood sugar in behavior in the individual child.


[Editor's comment: Exactly the same comments apply for adult patients with very high or very low blood sugars! WWQ]
