Nutrition Services

Registered dietitians are experts in food and nutrition who motivate, counsel, and advise patients on what, when, and how much to eat and drink, to achieve specific health-related goals and to lead a healthy lifestyle. Utilizing a multidisciplinary and collaborative approach, dietitians in the Center for Advanced Digestive Care (CADC) at NewYork-Presbyterian/Weill Cornell Medical Center work closely and communicate regularly with other practitioners to identify the nutritional needs of each patient throughout his or her care.

Since many digestive diseases and disorders occur before or during adolescence, our dietitians focus on correcting nutritional deficiencies early to support normal growth and development. Each pediatric patient undergoes a thorough nutritional assessment. Our nutrition team helps guide all patients toward a sound diet and appropriate nutritional therapies to prevent and treat digestive disorders and to support recovery and healing after surgery.

Medical nutrition therapy is provided through both one-on-one visits and group counseling sessions to help address nutritional issues associated with acute and chronic digestive diseases and disorders, the side effects of cancer treatment, and weight management, wound healing, digestive challenges, and anatomical changes associated with surgery. Our registered dietitians often speak at patient education events and support groups.
