Complementary and alternative medicines (CAMs) are frequently discussed by people with Inflammatory Bowel Disease (IBD). The aim of this study is to explore CAM use in Australians with IBD. This cross-sectional study was conducted via an anonymous online survey, predominantly distributed through IBD-specific social media accounts. Data collection occurred over a three-month period in 2021. Descriptive statistics, Chi-Square tests, and binary logistic regression were used to analyse quantitative data. A simple thematic analysis was conducted for qualitative free-text responses. Of the 123 responses, acupuncture (12.2%) and chiropractors (8.9%) were common CAM practitioners accessed. CAM practitioners were perceived to be 'very helpful' compared to mainstream health practitioners. The most common CAM products reported were vitamins (51.2%), probiotics (43.9%), and herbal medicine (30.9%). Common reasons for use were improved perceived improvements to wellbeing or for long-term management of IBD. Females were more likely to access CAM practitioners (OR 12.6, 95% CI 1.62-98.1, p = 0.02). Doctors were the participants' primary source of information (64.2%), although many expressed dissatisfaction with conventional therapy and the desire for a more holistic approach to care. The use of CAMs in this sample was high. Limited research into the efficacy and safety of these therapies may prevent health professionals from discussing their use with patients. Improved communication with health professionals will allow patients to be active partners in their healthcare plans and can heighten patient satisfaction with conventional therapy.
