3. Dark, Tar-like Stool: A Sign of Upper Digestive Tract Issues
Dark, tar-like stools stand out. They’re different, and they’re concerning. The medical term for this is melena. Melena signals bleeding in the upper digestive tract. This includes the stomach, small intestine, or the colon’s right side.
Why the dark color? It’s due to blood undergoing digestion. Blood turns dark as it travels and gets processed. And what causes this bleeding? There are several reasons. Stomach ulcers are a common cause. Gastritis is another. Even some medications can lead to melena.
Now, occasional dark stools might not be melena. Certain foods and medications can darken the stool. Iron supplements are a common example. But persistent dark stools require attention. It’s essential to get a clear diagnosis. This ensures the right treatment for the underlying cause. (3)
