Question 1

what causes stool to be black or dark green?

Accepted Answer

Dark stool: 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. Silver-colored stool suggests bleeding from the biliary tree. Get checked.

Question 2

after drinking for a few nights, i noticed my stool was very dark, either black or dark green, should i seek medical attention?

Accepted Answer

Yes, immediately.: Black stool, especially when slightly loose and rather foul-smelling, often is an indication of internal bleeding of the upper digestive tract. The black stool is digested blood, and it is referred to as melena. Because the bleeding could still be on going, this is considered an emergency. You should go to the nearest emergency room, or call 911 if you are lightheaded. Do not delay. Good luck.

Question 3

if my stool is black and/or dark green what is wrong?

Accepted Answer

Although either of : These can be related to medication or foods which have been ingested, green stool is usually associated with rapid transit time through the GI tract.  If stool is black, tarry and malodorous - that could be melena (gi bleeding).  For latter, please seek prompt medical evaluation. Take care.

Question 4

somethimes i have dark green or black stool for a day or two than it changes back to the normal colour.the dark stool appears once in many week and it's only temporary. shall i be worried about this? do serious conditions cause permanent black stool?

Accepted Answer

: Black stool is concerning since this could be due to blood in your stools. The green stool is most likely due to something you are eating. You may want to have your doctor test your stool for microscopic blood to be certain you are not having blood in your stools, especially when the stools are black. If it is blood, you should see a GI doctor. Good luck to you!

Question 5

No: You may take a fiber laxative like Metamucil and drink enough water daily so that your urine is colorless. For the long term you may try to increase your intake of fiber foods. Consult this site for fiber foods.

Accepted Answer

: Dark, tarry stools can be a sign of internal bleeding. If this is the case, it can be an emergency. It would be worthwhile for you to be checked out ASAP. Good luck.

Question 7

my stool is really dark green almost black and i have really bad stomach cramps. what is happening?!

Accepted Answer

See your doctor: You should see your doctor.  A test of the stool can make sure no bleeding in the intestinal tract is happening.  Stomach problems such as gastritis or ulcers could do this, as well as gallbladder problems.  May be able to be treated with simple medications.  Don't try to treat this yourself - call your doctor.

Question 8

Accepted Answer

Unlikely: It is unlikely that the broccoli had even made it out of your stomach at that point let alone through the rest of your digestive tract.  BM probably unrelated.

Question 9

Accepted Answer

Varies : Signs and symptoms of colon cancer vary tremendously, certainly would be extremely rare in a 19 year old.  Abdominal pain, change in bowel movements, unexplained weight loss,  abdominal fullness, nausea  are among the more common presenting symptoms.  I would not hesitate to be seen and discuss directly with a doctor.

Question 10

Accepted Answer

Stool: Dark green can be due to rapid transit of feces through GI tract. If stool is black, tarry & malodorous that could represent a GI bleed & would warrant prompt medical evaluation.
