What causes stool to be black or dark green?

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.

What is it when your stool is black not sure if this is normal or a problem

What is it when your stool is black not sure if this is normal or a problem

It : It is unclear what context your black stool occurred or the charcteristics of the stool, besides the color. Stool normally is brown because of the presence of bile in the stool. Bile is made by the liver, concentrated and stored in the gallbladder, and secreted into the intestine to aid in the digestion of food. Depending on the amount of bile it contains, the normal stool color can range in color from light yellow to almost black. Stool color can change for a variety of reasons. Some stool color changes may signify an underlying medical condition, and others may be due to ingestion of food or medications. Blood from the stomach or upper intestines can turn the stool color black and sticky, described as black, tarry stool, associated with a distinctive foul-smell from the actions of the digestive enzymes on the blood. Patients may be anemic if this is acute or long-lasting. Causes of this include ulcer disease, medication use (that cause ulcers, e.g. Aspirin, ibuprofen), use of anticoagulants, liver disease, intestinal or stomach masses. Other causes of black stool are iron pills or bismuth-containing medications (such as pepto bismol). If the stool color is dark because of any of these medications, it is typically not sticky in texture and is not foul-smelling. ...Read more

How long after taking iron tablets will my stool remain black? I stopped on friday and I have a bm once every 3 or so days and still black :/ nervous. They are formed; but black.

Don't worry: If you have a bm only once every 3 days, this means that the iron would stay in the stool until you have the next bm. If the dark color extends beyond 2 bm cycles, then you should get checked out. ...Read more
