Symptoms were recorded daily in diary cards during four 4\u2010week periods along the study. Bristol Stool Scale (BSS) was used to define bowel habit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Four\u2010hundred patients completed the study. Rome II showed low\u2013moderate agreement (42%) with BSS to define bowel habit. Frequency of constipation and diarrhoea showed little changes throughout the study. Over 50% of the patients had the same bowel habit when each diary was compared with the next one. A third of patients maintained the same habit throughout the study. Most changes occurred from\/to mixed or unsubtyped IBS. Only 14% of cases changed from constipation to diarrhoea or vice versa.

Changes in IBS subtypes are common, but changes between constipation and diarrhoea are rare.
