Peter Whorwell, MD, The University of Manchester, Manchester, UK

Dr. Whorwell is Professor of Medicine and Gastroenterology at The University of Manchester in the UK. His research interests include the epidemiology, pathophysiology and treatment of functional gastrointestinal disorders including irritable bowel syndrome, functional dyspepsia, chronic abdominal pain and non cardiac chest pain. He also studies the mechanisms and uses of hypnosis in treating these disorders.

Carlo Di Lorenzo, MD, Ohio State University, Columbus, OH

Dr. Di Lorenzo is Chief of the Division of Pediatric Gastroenterology at Children’s Hospital of Columbus, and Professor of Clinical Pediatrics at The Ohio State University College of Medicine. He has published more than 100 peer-reviewed original articles, serves on many professional organizations, and chairs the Adolescent Committee of the Rome III criteria.

Research needs for kids and teens  ►Treatment advances and needs: functional disorders ►Treatment advances and needs: motility disorders











Brenda Toner, PhD, University of Toronto, Canada

Dr. Toner is Professor and Director of the Women’s Mental Health Program at the University of Toronto, Canada. Her interests include health related problems that are disproportionately diagnosed in women, and factors in the lives of women that cut across diagnoses. Dr. Toner has received international recognition for her work on cognitive-behavioral therapy for IBS.

Challenges: Overcoming Labels in IBSApproaching Treatment











Brennan M.R. Spiegel, MD, David Geffen School of Medicine at UCLA, Los Angeles, CA

Dr. Spiegel is the Director of the UCLA/VA Center for Outcomes Research and Education, and is particularly interested in the role of the physician-patient relationship in IBS.

Diagnostic advances: Symptoms and the roles of biological markers  ►Treatment status ►Visualizing and validating functional GI disorders












Gary Mawe, PhD, University of Vermont, Burlington, VT

Dr Mawe is a Professor in the Department of Anatomy and Neurobiology at the University of Vermont. His research interests include neural regulation of the digestive tract, particularly understanding changes in enteric neural circuits that contribute to altered gut function in inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). 

Diagnostic advances: Multiple factors and identifying biomarkers  ►Serotonin 











Lin Chang, MD, David Geffen School of Medicine at UCLA, Los Angeles, CA

Dr. Lin Chang is a Professor of Medicine at UCLA, Co-Director and Head of the Clinical Program at the Center for Neurovisceral Sciences & Women's Health; and Director of the Women's Digestive Health Center at UCLA.

The Symposium: What is it all about?

Every 2 years since 1995, IFFGD has been hosting a professional meeting - the International Symposium on Functional Gastrointestinal Disorders. It brings together adult and pediatric clinician specialists, primary care physicians, social scientists, basic scientists, physiologists, nurse practitioners, physician assistants, trainees and others in medicine and related fields to learn about progress in the field of the functional and motility gastrointestinal (GI) disorders. The meeting helps advance research and improve patient care. In this video, several participants explain the value and uniqueness of this symposium. Go »
