Description of intervention(s) / exposure
Primary sclerosing cholangitis (PSC), is a rare autoimmune liver disease with no effective medical therapies. The aetiology and pathogenesis of PSC are unknown, however, evolving evidence suggests dysbiosis of the gut microbiota may be a contributing factor. Diet is a key fertiliser of gut microbiota and therefore has potential to be a modifiable risk factor. However, very limited data on dietary patterns and trends of people with PSC exist
This is an observational study of habitual dietary intake where participants will be asked to complete online questionnaires and a food frequency questionnaire to observe habitual dietary patterns and the dietary perceptions and food beliefs that inform dietary behaviour and food choice. This will occur at a single timepoint and the online questionnaires are expected to take 20-30 minutes to complete
