Rosemarie Fisher, MD, is a gastroenterologist who treats patients for a variety of conditions, including malnutrition and short bowel syndrome, and she cares for patients who need nutritional support. She also treats patients with irritable bowel syndrome.

“I truly enjoy talking to patients and helping them deal with their illnesses,” says Dr. Fisher. “The role of nutrition support in maintaining a patient's health is part of this.” She says the best part of her work is being able to help people through difficult times and then continue to follow them for years.

Dr. Fisher is a professor emeritus at Yale School of Medicine. She has focused her research on various clinical projects related to both gastrointestinal diseases and nutritional support. She is director of the Yale New Haven Hospital Nutritional Support Team, which has provided her with a multitude of opportunities for the clinical investigation of patients undergoing nutritional support, she says.
