I had half my colon removed due to cancer in 2009, since then I have had loose, watery stools, which get frothy and gas and bloating is quite a problem also. Pain is common during these episodes also. My taste is almost gone and I am nauseated most of the time. My doctors either don t want to or dont feel the need to try to figure what is causing this problem. I had a huge hernia removed from my upper chest almost two years ago.
