I am a man, 36 years old, with a history of IBS, mucus in stool, hemorrhoids and chronic constipation. Tonight after being constipated for approximately 2 days I had to large BM s, the second produced a large amount and after looking into the toilet I noticed a large mucus blob floating to the surface of the toilet, I examined it further and noticed that there was some blood (red) in the mucus. I have had blood in my stool before and have had hemocult samples before with no adverse diagnoses. And while I commonly have mucus in my stools, especially after being constipated, I have never noticed blood accompanying this phenomenon. Thoughts?
