Food is the most important synchronizer of gastrointestinal motility and secretion.
Many patients with functional bowel or anorectal disorders complain of fecal urge and stool output after eating.
Dr Michel Bouchoucha and colleagues performed a prospective observational study of 408 consecutive outpatients with functional bowel and/or anorectal disorders filled Rome III questionnaires.
The team measured depression and anxiety scores, a physiological evaluation.
Univariate analysis and multivariate logistic regression were carried out according to the presence or not of stool output after eating.
|Defecation after eating was observed in 21% of patients|
|European Journal of Gastroenterology & Hepatology|
The team observed defecation after eating in 21% of patients.
These patients were not different according to the demographic characteristics of sex ratio, age, and BMI.
In contrast, the researchers found they had lower state anxiety, but similar scores of depression, and trait anxiety.
They had similar manometric characteristics, but a greater response to eating in all segments of the colon.
The team found an increase in the frequency of functional diarrhea, and levator ani syndrome, but no other functional bowel disorder including irritable bowel syndrome and its subtypes was found.
Dr Bouchoucha's team comments, "Stool output after eating is associated with clinical disorders but not physiological parameters."
"This symptom is not associated with irritable bowel syndrome, but a higher frequency of functional diarrhea."
