​Diagnosis of Gut Disorders & New Technology

​Chronic GI symptoms are common, however diagnosis remains challenging. The field has suffered from a lack of reliable methods to identify actionable biomarkers, in order to differentiate underlying causes. These underlying causes may also be complex, encompassing neuromuscular pathologies, gut-brain axis disorders, visceral hypersensitivity syndromes, and dysbiosis with immune activation.  This talk will address some of these challenges, with a particular focus on work recently conducted in New Zealand to develop new technologies to deliver novel actionable biomarkers for GI symptom disorders.  These biomarkers, generated by non-invasive 'GI mapping' (electrophysiology) medical devices, are showing promise to robustly separate pathological causes to better direct care.  Case examples will be provided in conjunction with Dr Daker's adjacent talk on abdominal pain.
