Hi my husband had a colonoscopy 2yrs ago since then he s experience some problems with his bowels. Hs s had blood in his stool which has ceased now. He went to the Dr and they were a bit puzzled and told him he wasn t a book case so they ordered some lab work on his which he tested for H.Pylori and a colonoscopy has also been sched for him to have. Should he stil have the colonoscopy test done since they found this bacteria in his system?
