Abstract

BACKGROUND:

Watery stools are equated with rapid and hard stools with slow intestinal transit; however, the relation between stool form and transit through specific regions of the gut is not clear cut. In addition, more information is needed on interindividual variability of these measurements.

AIM:

To examine the relations between stool form and gastric emptying, small bowel and colonic transit.

METHODS:

Regional gut transit was assessed scintigraphically and segmental colonic transit was also quantified by radio-opaque markers. On two occasions, 32 healthy volunteers (12 men, 20 women) were studied, women during the follicular and luteal phases of menstruation, men twice within a similar four week period. Diets were standardised and stool form was recorded on a seven point scale.

RESULTS:

Women had significant harder stools; hard stools were correlated significantly with slow transit and loose stools with fast transit through the colon.

CONCLUSIONS:

Stool form could not be related to gastric emptying or small bowel transit.
