sorry if i'm suggesting too many changes as part of the history of ibs request from agne i was thinking of describing how idea of the cause has changed over time so this would become the what causes ibs section right now pathophysiology oh that is hard to spell is a mixture of causes and co morbidities so i'd suggest splitting pathophysiology into what causes ibs and what conditions accompany ibs co morbidities i probably won't get to this for a week or so i'm working on another page on the medical history of emerging gastrointestinal pathogens like h pylori giardia and enterotoxic e coli thanks
