Dark Green Tarry Stool
Yesterday I had soft, VERY green stool. Today, I had a very hard, very dark green, almost black stool. Is this cause for concern?
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.

I wouldn't worry too much about it. Melena is a recurring issue and due to small amounts of bleeding in the GI tract, not just a one time deal. It is caused by the oxidation of the iron (which is present in our blood cells) by our digestive enzymes. Sometimes there is food coloring in ice cream, which can definitely color your stool. Just keep an eye on it for now. ...Read more
