internal bleeding

I became anemic for about 6 mo. as a result of GBS-I believe because of the Neuontin that I was taking(pharmiscist thought). I was put on iron tablets for 6 mo. and that cured the anemia. Hope this helps. My internist wanted to do a upper and lower GI to determine cause of anemia,which is typical way they proceed, however, my plasma phersis doctor, a friend, said no to that because it was too invasive to my recovery so he suggested the fecal occult test first, which came back negative, and then the internist put me on the iron tablets and everything was fine. Hope this helps. elayne
