Sorry if Im 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 comorbidities  So Id suggest splitting Pathophysiology into What Causes IBS and What Conditions Accompany IBS Comorbidities  I probably wont get to this for a week or so  Im working on another page on the medical history of Emerging Gastrointestinal Pathogens like H Pylori Giardia and Enterotoxic E Coli  Thanks
