Diagnosis & Treatment

Treatments of endocrine disorders are complex and may include oral medication, daily home injections or specialized in-office injections on a recurring basis.

We also offer more detailed diagnostics if needed, including testing for growth hormone deficiency, early or delayed puberty, or adrenal insufficiency. These specialized tests are scheduled separately.


Our Pediatric Endocrinology researchers engage in a wide range of research activities to expand the understanding of endocrine disorders in children and adolescents, and to innovate more effective strategies for the prevention, management, and resolution of endocrine disease. We continue to break new ground in our understanding of conditions including diabetes, congenital adrenal hyperplasia, pediatric growth, and metabolism.
