Dr. Biesiekierski discusses her groundbreaking research, highlighting the interaction between mind and body in food sensitivity reactions in irritable bowel syndrome (IBS). Her research was a key finding to support IBS (and other conditions) being classified as Disorders of Gut-Brain Interaction (DGBI).

She is a researcher and senior lecturer with the Department of Nutrition, Dietetics and Food at Monash University in Australia.

Health psychology focuses on how biological, social and psychological factors influence all aspects of health. However, many people are reluctant to see a health psychologist because the recommendation can sound like, "Your symptoms are in your head" or "Your symptoms are caused by stress; just relax, and you will feel better." This is such a prevalent problem that I wanted to learn more about this field and explore the difference between health psychology and general mental health counselling. We are fortunate to have Dr. Megan Riehl on the podcast today to explain the difference.

Dr. Megan Riehl is a GI psychologist who is a key opinion leader in the area of psychogastroenterology. She is an Associate Professor of Medicine and the Clinical Director of GI behavioral health at the University of Michigan. She is also the Director of Behavioral Health Services and Support for GI OnDemand. Dr. Riehl's clinical research focuses on the delivery of GI behavioral health treatment for patients with disorders of the gut-brain and IBD. Dr. Riehl participates on several national committees dedicated to research and education to enhance the psychosocial functioning of patients with gastrointestinal problems. Together with expert GI dietitian Kate Scarlata, she has co-authored a new book for those living with IBS – Mind Your Gut.

Mind Your Gut is available in March 2024. Learn more here.

Food sensitivity is rarely a simple cause and effect. Biological and psychological factors interplay to produce symptoms. We will talk about the role of symptom expectancy (i.e., nocebo response) in exacerbating symptom severity and how minimizing expectancy can dramatically improve quality of life.

We will discuss how signals between the gut and the brain (gut-brain access) become amplified in irritable bowel syndrome and strategies for calming this communication. The brain similarly communicates with other body parts, so the concepts and strategies apply to symptoms throughout the body.
