In addition, the maintenance of normal thyroid status through childhood is necessary for normal growth and neurodevelopment. Best outcome in pediatric thyroid disease requires early detection as well as appropriate therapy with careful monitoring. These tasks are generally accomplished through successful collaboration between primary care providers and endocrine specialists. With an appropriate index of suspicion, pediatric thyroid disease can be detected in early stages and outcome is usually excellent. This chapter begins with a review of thyroid physiology and clinical testing. We then present diagnostic approaches to common pediatric thyroid disorders, grouped into the categories of hypothyroidism, thyrotoxicosis, and nodular thyroid disease.
