Background: Patients with ulcerative colitis (UC) often report dietary intolerances. Our aim was to assess the effects of proctocolectomy (PC) for UC on dietary intolerances. Methods: A novel disease-specific questionnaire was used. Results: Eighty-seven percent of patients reported 338 dietary intolerances. Of 225 preoperative dietary intolerances, 151 (67%) resolved/improved, 56 (25%) were unchanged, and 18 (8%) were exacerbated after PC. A total of 113 dietary intolerances developed only after PC. The incidence of specific dietary intolerances in patients 10 years and older post-PC was similar to patients younger than 10 years post-PC except for a lower incidence of caffeinated beverage (P = .01) dietary intolerances 10 years or more post-PC. Intestinal symptoms, bowel function, and activities of daily living largely improved after PC. Extraintestinal UC symptoms worsened or failed to improve in 74%. Conclusions: PC for UC frequently improves preoperative dietary intolerances. Some patients, however, are at risk for onset of new dietary intolerances after PC. Studies examining traditional symptoms in UC patients pre-PC and post-PC may be enhanced by examining effects on specific dietary intolerances.
