Hello, just wondering if you can have IBS without abdominal pain? I have a camera colonoscopy in a week and dreading it. This has been arranged because my main symptom is nausea - really bad nausea out of the blue without the vomiting though. I also get loads of gas, stools that alternate between looking like hard tiny twigs, loose pencil shaped and normal. My biggest fear is cancer because the nausea is so bad but my GP said he didn't think it was and to trust him as a GP. If I am very very careful with what I eat, ie SMALL amounts of chicken, potato, small yoghurt etc etc I seem to be ok with the nausea but still feel like my bowel needs emptying......So just wondering if anyone else has IBS with these symptoms. My GP said nausea can be indicative of IBS. Thanks, Sarah.
