Patients with ulcerative colitis often report dietary intolerances.
Dr Max Schmidt and colleagues from Indianapolis, USA assessed the effects of proctocolectomy for ulcerative colitis on dietary intolerances.
The research team used a novel disease-specific questionnaire was used.
The team reported that 87% of patients had 338 dietary intolerances.
Of 225 preoperative dietary intolerances, 67% resolved/improved, 25% were unchanged, and 8% were exacerbated after proctocolectomy.

A total of 113 dietary intolerances developed only after proctocolectomy.
The incidence of specific dietary intolerances in patients 10 years and older post- proctocolectomy was similar to patients younger than 10 years post- proctocolectomy.
The age differences were not noted for a lower incidence of caffeinated beverage dietary intolerances 10 years or more post- proctocolectomy.
The researchers observed that intestinal symptoms, bowel function, and activities of daily living largely improved after proctocolectomy.
Extraintestinal ulcerative colitis symptoms worsened or failed to improve in 74%.
Dr Schmidt's team commented, "Proctocolectomy for ulcerative colitis frequently improves preoperative dietary intolerances."
"Some patients, however, are at risk for onset of new dietary intolerances after proctocolectomy."
"Studies examining traditional symptoms in ulcerative colitis patients pre- proctocolectomy and post- proctocolectomy may be enhanced by examining effects on specific dietary intolerances."
