PREDICT-FD
This study aims to investigate whether measuring electrical activity in the gut can help predict who is most likely to benefit from dietary treatment for functional dyspepsia.
What's involved?
Taking part involves a 4.5-hour study visit at the University of Auckland in Grafton, followed by a four-week dietary programme.
At the study visit, you will:
- complete a test that measures electrical signals in the gut, similar to an ECG
- eat a standard meal and monitor your symptoms during the test
- complete questionnaires about your gut symptoms and mental health
- complete a food record.
Much of the study visit involves monitoring and observation, so you are welcome to read a book, work online etc.
After the study visit, you will:
- follow a low FODMAP diet for 4 weeks, including personalised support from a trained student dietitian on how to do this
- complete follow-up questionnaires and a food record at the end of the four weeks.
Participants will receive a $50 voucher after the study visit and a further $50 voucher on completion of the study.
Eligibility criteria
To participate, you must:
- be aged 18–65 years
- live in Auckland
- have been diagnosed with functional dyspepsia by a GP or gastroenterologist.
We may also be able to include people who experience symptoms consistent with functional dyspepsia, such as bloating, early fullness, stomach pain, or stomach burning.
