What can i do about my seemingly very irritable bowels? they have been this way my whole life.

R U sure U have IBS?: The GI tract has a very limited # of symptoms to signal its distress--nausea/vomiting, diarrhea/constipation, bloating, pain, fullness, bleeding, etc. As you know, many of these characterize ibs, but are also seen with inflammatory, infectious, ischemic, malabsorptive, and functional disorders. Directed lab work, imaging, biopsies, stool studies are appropriate in excluding non-ibs pathology.
