Question: Black Stools

 JKF - Thu Jan 19, 2006 3:56 pm

I am new to this forum. Infact just today. For about 8days I have had a problem with black stools-mostly diarrhea. Sometimes during the day the stools would be normal--but mostly diarrhea and black at that. I cant get in to miy gastroenterologist til Feb. 15. He had me take a CBC and it was normal. I have had irritable bowel syndrome for a long time but nothing like this. There is nothing I a m eating the would cause this-no medicine that would cause it either. Sometimes it is mucousy and sometimes withstuff like coffe egrounds at the bottom of the stool. Does anyone have an idea whether this could be serious or not or what it does mean. Thanks a lot. JKF :roll:

User avatar Dear JKF,
you do not mention your age. Any change in bowel movements habits must be investigated after the age of 50. However if you suspect some blood content in your stool, this is very unlikely from what you report.

Dear Doctor
I am 58 years old. Now my bowel movements are part black and part brown. I wonder if it could be gastritis. I ate some spicy chili the night before this began to happen. I don't eat spicy foods usually because I don't like them. The day after I ate it I felt bad and had diarrhea. I had gall bladder surgery a year ago and have battled diarrhea since then. It is the blackness of the stools that have me baffled. Thanks for your information. Anymmore you can give I would appreciate it. JKF

Dear Doctor,
I just had a small bowel movement and now it is bright red blood in the stool and on the toilet paper I am confused. . JKF

User avatar Indeed this is confusing.
You need hands-on medical attention.
Why I have thought very unlikely a bleeding in your case is that in order to become black, blood from the first part of the gut must be degraded, a process that takes several( 6-8) hours. In the case of diarrhoea this process usually does not have time to develop .
This black- brown-red stool sequence that has developed lately is quite disturbing.
Please see a doctor,and
Good luck!

Der Doctor,
I got in today to see my gastroenterologist and he has scheduled me for a colonoscopy on March 21. He thinks I might have polyps. My hemoglobin count is good so I havent had a lot of bleeding. I am glad I am on the way to finding out what is wrong. JKF

I had the colonoscopy yesterday and it was determined that i have diverticulosis and internal hemmorhoids. That kind of explains the red blood on the toilet paper and the stool but does not explain the black diarrhea which I still have occasionaly. Could it be something to do with my stomach. It seens to happen after I eat spicy foods I think but not always. Should my stomach be checked out? JKF
