i've been taking colonclenz for 2 days maybe 3. i take 2 pills a day. this morning i had diarrhea which was very dark, maybe even black. is this ok?

Accepted Answer

See MD: The  GI tract moves food, , and eventual stool through the GI tract, so colon cleansing is not ordinarily needed nor should it be taken for any reason.
Gi problems  that prevent normal bowel movements need to be reported to md
    colon cleanse may contain laxatives that of course may cause diarrhea. Black stools may  represent bleeding in the upper part of the GI tract,  so report it to md.

Diarrhea: Absent blood or mucous the consistency and color of the stools during an inflammation of the GI tract will vary greatly with both the cause and what you have eaten.  If this persists you may want to go and be seen by your PCP.

Question 8

is black diarrhea normal when sick?

Accepted Answer

Not normal: Truly black diarrhea is never normal.  Black, tarry, smelly stools can be caused by gastrointestinal bleeding.  Other things that can make stool look black include iron supplements and pepto bismol, (bismuth subsalicylate) which some people take for diarrhea.  If you think you might be bleeding, you should go to an emergency room.

Not likely: The biggest concern would be a gastrointestinal bleed. Any such diarrhea should be evaluated.

Question 10

what kind of sickness causes my diarrhea to be black?

Accepted Answer

Blood, pepto bismol (bismuth subsalicylate): Truly black diarrhea is concerning for digested blood and evaluation a doctor is recommended.  Dark green diarrhea is more common and related to bile in the stool.  Otherwise the color of stool is related to the colon of whatever is consumed.  Also, bismuth containing anti-diarrheals (pepto bismol, kaopectate) make stool black.
