My constipation is due to nerve damage in my colon...the nerves just don't work right. I was taking probiotics which really helped but when my GERD started and I had to take all this medication, it just stopped me cold...nothing wanted to move, so I'm sure the drugs really exacerbate the problem.
Yes, you may have a bad taste in your mouth from bile. If you have a reflux problem, then anything in your stomach including acid, food or bile can potentially reflux up. So, you might consider that some bile may come up if you have a constipation problem. Talk to your NP and see what she thinks. I know that the Zelnorm is such a relief to me. It takes a while for it to start working efficiently (about two weeks) but so far I'm doing good with it.
