Health tip: Medical problems may lead to hyperactivity

(HealthDay News) — Kids are typically little balls of endless energy. But for some, hyperactivity can signal an underlying health problem.

While each of us has a different threshold for measuring hyperactivity, excessive movement is considered a problem if it interferes with school work or the ability to fit in with other children.

The ADAM Encyclopedia offers this list of potential health triggers for hyperactivity in children:

Having attention-deficit disorder. Having a disorder of the brain or central nervous system. Having an emotional disorder. Having hyperthyroidism, an overactive thyroid gland.
