I have had thinner stools since December, and they are getting thinner. I saw a gastroenterologist, and he suggested a colonoscopy. I can't bare the thought of that! [img]smileys/smilies_03.gif[/img] I had an upper endoscopy years ago, but my phobia wasn't nearly as bad as it was then. Has anyone had a colonosocpy? Does anyone else with IBS have really thin stools?Edited by: Girlygirl1980s
