Can healthy volunteers participate?
No
Key exclusion criteria
- Patients with 'alarm' signs or symptoms (significant unexplained weight loss, evidence
for gastrointestinal bleeding, iron deficiency anaemia, new onset GI symptoms) will be
triaged to undergo urgent clinical work-up before they can be considered for inclusion
into the study

- Patients with mild or moderate symptoms (e.g. not requiring clinical work-up or who
will likely spontaneously improve) will not be eligible for inclusion into the study
and will be managed as clinically indicated.

- Patients with any comorbidities that would interfere with the objectives of these
interventions will be managed via the routine clinical pathways.

- Patients with a prior history of any eating disorder, wait listed for bariatric
surgery or have had bariatric surgery will be excluded

Summary
Brief summary
This research project aims to test whether early interventions delivered remotely and prior
to integrated care clinic appointments are effective. Patients with chronic unexplained
gastrointestinal symptoms will initially undergo structured assessment of symptoms and wheat
intolerance delivered remotely. Patients who continue to experience symptoms will then be
randomised to a pre-consultation intervention ((a) standardised dietician supervised
intervention, b) exercise intervention, c) internet delivered cognitive behavior therapy or
d) nothing) followed by randomisation to the consultation intervention ((a) consultant-led
outpatient clinic or b) a integrated care clinic depending on their response to the initial
intervention.
