Thyroid Disorders: Common Reasons for Pediatric Endocrinologist Referral

The document discusses thyroid dysfunction, which is one of the most common reasons for referral to a pediatric endocrinologist. The thyroid hormone axis, an endocrine system with many important actions including growth and development, is a potential cause of numerous signs and symptoms. Despite the lack of clinical evidence supporting this practice, thyroid function is routinely checked as part of the annual physical examination, leading to an increase in healthcare costs. Age and clinical status significantly influence what are considered normal values with thyroid testing.
