My diet consists on mostly fatty food, my stools are usrually formed brown with a few light/white spots. Today, I had a small BM, app 1cmx1cm. One end was white the other was brown and it was floating. Should I be concerned since my stools are normally brown and formed? I had a colonoscopy and EGD, both WNL except some diverticulum and internal hemrrhoids. I have been taking Metamucil 5 tabs,po,daily since DX of diverticulum in colon. I do not drink alcohol and never have.
