OBJECTIVE: Diet, visceral sensitivity, and psychological distress play an important role in Irritable Bowel Syndrome (IBS). This study focused on the relation between IBS severity, foods, visceral sensitivity, and anxiety/depression.
PATIENTS AND METHODS: Patients with IBS were investigated through (1) IBS-symptoms severity score (SSS), (2) self-reported food intolerance, (3) visceral sensitivity index (VSI), and (4) Hospital Anxiety and Depression Scale (HADS). Seventy-seven patients agreed to participate in the survey. Of them, 64 (83%) showed IBS according to Rome IV criteria and were included in the final analysis. Patients with IBS-D were 30 (47%), with IBS-C 27 (42%), and with IBS-M 7 (11%).
RESULTS: Fifty-eight patients (90%) considered at least one foodstuff as IBS trigger. Amine-rich foods represented a symptom trigger for 77% of patients, those with lectin for 70%, IACs by 48%, and capsaicin by 37%. Overweight was significantly associated with amine-rich foods (p=0.015), age >45 years (p=0.001) and non-smoking condition (p=0.033) with lectin-rich foods, male gender (p=0.005) and overweight (p=0.027) with capsaicin-containing foods. A positive VSI score was found in 59% of patients, and non-smoking condition was significantly associated (OR 10.03; p=0.009). No factors were associated with a positive HADS score, shown by 80% of patients. Severe IBS was shown by 63% of patients, being amine-rich foods (p=0.024), overweight (p=0.020), and female gender (p=0.029) independent risk factors while marriage/cohabiting a protective one (p=0.038). Amine-rich foods are an independent risk factor for severe IBS, along with overweight and female gender.
CONCLUSIONS: Clinicians should pay more attention to self-reported food intolerance in IBS patients. A personalized therapy including dietary advice as part of treatment could be of great benefit.Free PDF Download
