I was diagnosed with IBS a little over four years ago. The last month or so I've noticed allot of mucus when I go to the bathroom. I use to see a little from time to time, but this is allot! Sometimes its the only thing that comes out. And when I do actually "go" is thin most of the time. I am bloated allot! And the past couple of weeks, anytime I eat, I have to go to the bathroom. So I went to the Gastro doctor last week. He said I need to take Benefiber ever day and he also wrote me a prescription for Dicyclomine. What could it be? He said the next thing would be to do a colonoscopy.
