I picked E) inhibition of TNF-a because I thought 2 years of diarrhea sounds like IBD (specifically crohns Disease without bloody diarrhea vs uc which must have bloody diarrha). I still don't see any reason why I wouldnt guess that.

tinydoc  Nevermind just saw the "typically relieved with defecation" which is a pretty big indicator of IBS. +  
pg32  I still agree with you though. This sounds like a case of IBD and I picked E to try and tone down inflammation. Giving someone an opiate for intermittent diarrhea seems kind of dumb... +  
pg32  Just googled, "Indications for loperamide" and this is what came up: Imodium® (loperamide hydrochloride) is indicated for the control and symptomatic relief of acute nonspecific diarrhea and of chronic diarrhea associated with inflammatory bowel disease. +  
gyabo92  lol, I feel dumb. I knew it was IBS (half my fam has it and just manage through dieting). Went into overthinking hyperdrive, and all it was was your standard anti-diarrheal. step has taken away all my sanity. +4  

yo sketchy veterans.

do you remember that loping back and forth lop eared rabbit that was increasing the phasic segmentation and therefore icreasing stool transit time?

This is it now.
