Melvin Heyman, M.D.

Pediatric gastroenterologist

Dr. Melvin B. Heyman serves as chief of the Division of Pediatric Gastroenterology, Hepatology and Nutrition at UCSF. He also directs the Pediatric Gastroenterology/Nutrition training program and the Pediatric Inflammatory Bowel Disease Program at UCSF.

For the past four years, he has served as editor-in-chief of the Western Hemisphere for the Journal of Pediatric Gastroenterology and Nutrition. The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition recently gave Heyman its Distinguished Service Award, one of the highest honors in his field.

He is also the coauthor of the book "Feeding Your Child for Lifelong Health," which won one of the Will Solimene Awards for Excellence in Medical Communication from the American Medical Writers Association's New England Chapter.

At UCSF, Heyman also serves as a professor of pediatrics. His research focuses on nutrition issues; inflammatory bowel disease, or IBD; pancreatitis; and gastroesophageal reflux disease in children.

Heyman was one of the first to reveal the importance of nutrition in sickle cell anemia and helped develop procedures to diagnose liver-related problems in infants, as well as new treatments for children with IBD and gastroesophageal reflux.

He currently serves as co-chair of PROKIIDS, a Crohn's and Colitis Foundation of America-supported pediatric initiative to enhance research in childhood IBD. He also participated in the San Francisco Unified School District's Childhood Nutrition & Physical Activity Task Force to promote healthier foods in the local public schools. Since 2001, he has been instrumental in developing and maintaining a Northern California summer camp for children and adolescents with IBD.

Heyman earned a medical degree at UCLA and completed a pediatric residency at Los Angeles County + USC Medical Center. He also completed postdoctoral training in nutrition, earned a master's in public health, with an emphasis on nutrition, and completed a fellowship in pediatric gastroenterology at UCLA. In 1981 he joined UCSF, where he organized the pediatric nutrition support service and established protocols for pediatric gastroenterology.
