Bentyl
"I'm still waiting to see if it's Celiac disease or inflammatory IBS-D. After 3 weeks of constant diarrhea, dehydration and trip to ER tons of blood work all negative & stool sampes all negative and 16lb weight loss I got in with a GI doctor.  I'm waiting back for my inflammatory test & celiac disease test but in the mean time my GI doctor put me on bentyl 20mg up to 4 a times day to help with the diarrhea  which is the cause of the weightloss in only 3 weeks. It's worked wonders so far haven't had any diarrhea. I've only been on it 48hrs now. The only side effect I have noticed sometimes it makes my heart race a little for an hour. I have a follow-up with my GI in 3 weeks & hoping to come off of it and be back to eating normal, he thinks I had a viral that caused inflammatory IBS-D"
