Dear Doctor, I have orange-reddish bits in my stools. I had been having pain for about three weeks (I m getting an endoscospy to check for gastritis or an ulcer) but my pain is now gone, my endocrinologist assured me it was nothing more than eating sausages or something red but they orange-reddish bits have returned. I have diarrhea but think this could be attributed to medication which includes Bromopan and Pantacol.
