Dark colored feces or stool have deeper color (usually dark green, maroon, or black) other than the usual brown or yellowish brown color. Feces is a waste product from digestion of the food we eat.

  • Bleeding ulcer. An ulcer is a sore in the stomach lining that can cause bleeding. Two types of ulcers have been identified, the gastric ulcer or the poor man’s ulcer, and the duodenal ulcer or the executive ulcer. Gastric ulcers are caused by increased gastric secretions due to starvation or decrease in stomach food content. Duodenal ulcers are caused by stress. Stomach ulcers are primarily caused by the bacteria Helicobacter pylori.
