If the duodenal bulb is found to be bleeding and the labs are next to normal (slightly low MCHC), what is the protocol for stopping the bleeding? No, I m not a drinker, nor am I on anti steroidal meds. I ve been on Prozac, Mirapex and Synthroid 15 years however. Would you blame one of those meds? I also have MS and injected interferon many years, but stopped that 3 years ago and went to a glatiramer acetate, Copaxone. That too has been stopped over 6 months now. Your thoughts?
