Pediatric Gastroenterology



Support & Wellness Services

The care of children and adolescents with digestive diseases and disorders goes beyond diagnosis and treatment. For young patients, a digestive disease can affect the daily routine, diet, social interactions, and even time spent learning. The Center for Advanced Digestive Care (CADC) at NewYork-Presbyterian/Weill Cornell Medical Center understands this impact, and provides numerous services that go beyond treating the disease — often at little to no cost to CADC patients. These services include:

  • Nutritional counseling
  • Genetic counseling
  • Educational and emotional support
  • Peer-based experience sharing through our 1-to-1 patient support program
  • Transitional care as an adolescent approaches adulthood

Through all support services, CADC providers can help patients and families identify helpful tools and resources available to help them with their medical care.

School & Child Life Services

Digestive diseases can take young patients away from the classroom and activities crucial to their development. The staff at the CADC works with patients and families to address educational and emotional issues.

Because we know that any hospitalization brings with it anxiety and stress, we have several child life programs available that are designed to address your child's emotional needs and help make the hospital stay less intimidating.

Nutritional Assessment & Counseling

Nutritional counseling by registered dietitians at the CADC can help reduce disease recurrence and alleviate patients' symptoms. Mindful of the central role that nutrition plays in treating and managing digestive disorders, our pediatric gastroenterologists conduct a thorough nutritional assessment of all our pediatric patients, looking carefully at vitamin and nutrient levels, caloric intake, and overall well-being. Since many digestive diseases often occur before or during adolescence, we focus on correcting nutritional deficiencies early to support normal growth and development. Our nutrition team helps guide patients toward a sound diet and appropriate nutritional therapies to prevent and treat digestive disorders and to support recovery and healing after surgery.

Social Work

A GI diagnosis in childhood can be exceptionally troubling to young patients. Our pediatric social worker can help patients and their families understand and cope with the medical, psychological, and social issues related to their illness.

Jenisabel is passionate about trauma-focused work, crisis and grief counseling, individual, family and group therapy, socialization skills, meditation and serving children and families holistically to ensure their social-emotional well-being.

Genetic Counseling

Genetic evaluation and testing can help to make a definitive diagnosis in a child, as well as predict the risk of developing a digestive disease in future children or other family members. We perform a battery of molecular genetic tests for children with conditions that often run in families. Improved understanding of genetics allows us to offer earlier care and more targeted therapies to children with a family history of these disorders, giving them the opportunity to build healthy lives. Genetic education and counseling help patients understand and cope with the results of genetic tests.

Transitional Care

In many cases, your child's illness is a diagnosis that will require lifelong vigilance, special care, and follow-up. The CADC therefore has a transition program to help adolescent patients take charge of their own medical care when the time comes to move from pediatric to adult health care.

As a way to initiate a pathway to self-sufficiency and assist patients in taking charge of their health as young adults, the transition program begins during adolescence. Partnering with our patients, we introduce them to their new physicians and specialists; help them understand the critical importance of keeping up-to-date with their therapies and appointments; and provide them with the knowledge, skills, and confidence they need to make responsible decisions affecting their care. In addition to standard transitional discussions with to all patients and their families, the CADC has now offers a formal program for adolescent patients with Crohn's disease and ulcerative colitis due the chronic and often severe nature of their inflammatory bowel disease diagnosis.
