In this episode, Dr Krystyna de Lange hosts Associate Professor Dr Alireza Ahmadvand, a practising GP with a special interest in gastroenterology at the Princess Alexandra Hospital in Brisbane, to discuss disorders of gut-brain interaction (DGBI).

Dr Ahmadvand elaborates on what DGBIs are and provides the latest insights into the pathophysiology, mentioning conditions such as irritable bowel syndrome and functional dyspepsia. He explains the diagnostic criteria and the importance of recognising these conditions in general practice, and highlights the role of GPs in identifying and ruling out structural abnormalities before considering a DGBI diagnosis.

They also covered the multifactorial nature of these disorders, including the impact of psychological and psychosocial factors, such as stress, anxiety, and depression, and the interactions between gut microbiome and gut function. Dr Ahmadvand outlines when GPs should consider DGBIs and what red flags to watch for, emphasising the importance of comprehensive evaluations and specialist collaboration.

For management, Dr Ahmadvand advocates for a multidisciplinary approach involving dietitians, psychologists, exercise physiologists, and gastroenterologists to provide holistic care. Pharmacological treatments, diet modifications, and psychological interventions, such as Cognitive Behaviour Therapy, are also mentioned as part of a comprehensive management plan.

Lastly, Dr Ahmadvand points GPs towards the Rome Foundation's criteria, the Gastroenterological Society of Australia, and patient-focused platforms like Gut Foundation Australia and the IBS Network. He also encourages keeping alongside of the latest research through journals like Neurogastroenterology and Motility.
