Help! Stool dark brown - not black, definitely, but dark. Bits of food in it. Dullpain in lower right quadrant that I think is muscular, but not sure.

Don't panic, but...: Dark-colored stools may result from iron supplements, foods you eat (like a lot of spinach), substances (like peptobismol), but most significantly suggests bleeding. When blood is denatured by acid in your stomach, as from ulcers, stools will turn tarry ("melena"). Blood may also be ingested from nose bleeds, bleeding gums.

Greenish brown stool with black splotches/dots when wiping for the past week. Stool looks brown when I look at overall colour. Cause+when will it stop?

Hi should I worry if for the past couple of days my stool has been half brown half very dark brown very similar to black?

I don't think you: Need to worry, but I would continue to watch it. Very likely the dark brown digested products of something you ate or took (especially iron) were processed and collected up against your usual color stool. I predict in another day or two it will normalize. The most worrisome thing is if the black stool represents old blood is present. If it persists, see Doc; consider stool test for blood. ...Read more
