BackgroundsThe potential link between functional gastrointestinal disorders and eating disorders has been reported recently.AimsThe present study aimed to explore the relationship between orthorexic tendencies and irritable bowel syndrome (IBS)-related quality of life in IBS patients.MethodThis cross-sectional study was conducted with 121 IBS patients. The data were collected using Orthorexia Nervosa-11 (ORTO-11) to assess orthorexic tendencies, Irritable Bowel Syndrome Quality of Life Scale (IBS-QoL) to measure quality of life, and Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) to measure IBS symptoms. Food consumption record was taken to assess diet quality with the Healthy Eating Index 2015 (HEI-2015). The relationship between measured variables was assessed.ResultsThe mean ORTO-11 score of the patients was 24.76 ± 3.99. Most patients had poor diet quality (52.00%). A moderate positive correlation was found between ORTO-11 and IBS-QoL (model 0, p < 0.005 and model 1, p < 0.001) and a strong negative correlation between IBS-SSS and IBS-QoL (p < 0.001).ConclusionsIn conclusion, we can conclude that both altered IBS symptoms and orthorexic tendencies affect the quality of life of irritable bowel patients independently of each other. These findings provide valuable insights into the treatment of IBS and inform clinicians and researchers in the fields of gastroenterology, nutrition, psychiatry,and psychology.© 2024.
