Just went to the doctor today complaining of the same tummy trouble that I've been getting for the past few months (lost a lot of weight *10% body mass*). The doc suggested that it could be thyroid. Is thyroid linked to IBS? And the doc also asked be to undergo a colonoscopy, which i said i wanted a Virtual colonoscopy. Is it better to have a normal colonoscopy rather than a virtual one? Or there isn't really a difference? Which one would be able to give a more accurate result on my intestines? Sorry for so many questions. haha.Thanks, Kev
