Is it normal to have inconsistent stools with ibs?; some foods make me feel ill. bad cough sometimes after eating. voice always raspy. can't yell.

May be IBS plus LPR?: 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 studies are appropriate. The upper GI history suggests LPR (larygo-pharyngeal reflux).

IBS: Inconsistent stools is certainly common in IBS. They can have different frequencies (rare or oftent) or forms (loose, hard, thin, liquidy, etc). In fact alernating diarrhea and constipation is a well documented form of IBS.
