No big deal: Green stool is no problem. May be related to what you ate or drank. Go take your laxative at the time, you are supposed to take.Good luck for colonoscopy

Not concerning.: Stool color can vary because of a lot of factors, most notably diet. It is generally not a concern unless the store is bloody or solid black in color, due to bleeding, and will eventually return to normal. Green stool is not usually a concern. Be sure to drink all of your prep. Good luck.

Hi doctors! If consistent use of Miralax, Colace, stool softeners/laxatives does not seem to help/cure right away, is there a more invasive treatment for constipation that is used/helpful? I had an overall normal colonoscopy?

Good morning doctors. I had a colonoscopy at the end of last October, 2020..no colon cancer only diverticulosis. Lately my stool is dark brown to almost black, but not quite black. What may this be?

Occasional visible mucus in stool. Stool is well-formed and no blood. Went to primary care doctor who took occult test and culture of stool but no abnormalities found. Had a colonoscopy two years ago and everything was normal. Taking spironolactone ?
