It is a good idea to go to see a doctor or a medical specialist if you suspect you have IBS, and if you suffer from the more physical IBS symptoms of diarrhea or constipation, because it is these that are usually indicative of a more severe and much life-threatening disorder. If diarrhea persists after any suitable treatment has been given then it should be taken seriously because in itself IBS is not a life-threatening disorder, but the fact that such a disorder can exist by itself is a pretty good indication of something being seriously wrong. Any IBS sufferer should acknowledge that followed by a change in diet and lifestyle, and possibly medication, it can be taken care of.
