I have been diagnosed about 5 years ago with overflow diarhea. About every 2 weeks I have horrible bloating and gas and everything gets backed up. I get really sick and dehydrated.I am in the bathroom and than I sleep to get my energy back. My gastro doctor tried some things like zelnorm, others did not work. Later since Kaoepectate works, I stayed with this. I have not seen doctor for awhile but still suffering. I have anemia and very little iron.I get b-12 shots. Can anyone help. do I need to see a specialist. I have had 4 colonosopies,and enterclysysis to check large and small bowel, plus upper gi. I need help.Thanks.
