Services & Programs

Comprehensive Center for Congenital Adrenal Hyperplasia (CAH)

Pediatric Diabetes Program

  • The Weill Cornell Medicine (WCM) Pediatric Diabetes Program provides comprehensive diagnosis, treatment and support for children with type 1 and type 2 diabetes and their families.

Pediatric Obesity Program

  • Our team uses various approaches to address the growing problem of obesity and its metabolic complications, including insulin resistance, elevated blood pressure, dyslipidemia, fatty liver, and the progression of insulin resistance to type 2 diabetes mellitus. Our efforts range from prevention and education to understanding the causes of obesity, studying medication effects on weight gain and metabolic changes, and providing treatment options to our patients.
  • Adolescent Bariatric Surgery Program:  Severely obese (BMI>40) adolescents at the end of pubertal development who have failed other treatment modalities and have serious co-morbidities may be eligible for this program tailored for adolescents ages 15-18 years.
  • Kids and Teens Healthy Weight Program:  Developed and led by a Pediatric Endocrinologist and Registered Dietitian, this program is a series of interactive, age-appropriate small group sessions that focus on healthy eating and other important food and nutrition concepts.

Growth, Thyroid and Puberty Disorders

When a child is noted to have altered growth or energy levels, or abnormally early or late onset of puberty, it is important to consider possible endocrine causes of these signs and symptoms. Children referred for any of these concerns will undergo a full history and physical examination, and, if deemed appropriate, blood testing, x-rays and other imaging studies.

We provide comprehensive on-site testing, including growth hormone stimulation, suppression testing, and leuprolide stimulation testing when required for further diagnosis and management. We work together with patients and their families to tailor appropriate treatment plans for every child. 

Low Bone Mass

A variety of medical conditions, and even treatments, can interfere with proper bone mineral accrual in children, leading to an increased risk of fractures and low bone mineral density. We offer a comprehensive evaluation for children who are at high risk or already diagnosed with low bone mineral density or frequent fractures, including DEXA scans when appropriate.

We offer both inpatient and outpatient treatments for bone disorders, including bisphosphonate infusions when required.

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.

What to expect

As an academic institution, we are dedicated to training future physicians. At most of your visits, you will find physicians-in-training as your first point of contact. They may be medical students, pediatricians who are completing residency, or endocrinology fellows who have completed a pediatric residency. They are always under the direct supervision of your primary provider, who will be present during all visits.

At all visits, a comprehensive history and examination will be performed. Because much of what we do is engrained in growth and development, examinations often include staging pubertal development. It may help an older child, or a child who is anxious, to know that we will be examining their entire bodies (their pediatricians likely are, as well).

On occasion, blood tests, x-rays, ultrasounds or MRIs will be required for further evaluation. We offer same-day, on-site phlebotomy and simple radiology studies. However, some tests require specific timing (i.e. early morning) and others require scheduling a radiology appointment, and we may need to schedule your child’s testing for a future date under these circumstances.
