My 88yo dad was having some bleeding with dark colored stools 2 days ago. He went to see his primary care provider who did a rectal exam and said he had a fissure with some internal hemorrhoids. This weekend,the bleeding has subsided but his stools are black,shredded cheese consistency,he doesn t have much of an appetite but no pain or discomfort. What would this be an indication of? I plan to call tom. morning to see about getting him in with a GI doc.
