Why Is My Stool Black?

Categories health digestive-system dark-stool health digestion symptoms

Your stool can reveal a lot about your health. If you’ve noticed that your stool is black, there are several potential explanations, ranging from harmless dietary causes to more serious medical conditions. Understanding the underlying reasons is crucial to determine whether medical attention is required.

Common Causes of Black Stool

Here are some common reasons why your stool might appear black:

• Diet: Certain foods, such as black licorice, blueberries, or foods with dark food coloring, can temporarily turn your stool black.
• Medications and Supplements: Taking iron supplements or medications containing bismuth (e.g., Pepto-Bismol) often causes dark or black stool.
• Gastrointestinal Bleeding: In some cases, black stool could indicate the presence of blood in your digestive system. This may result from ulcers, gastritis, or esophageal varices. The technical term for this is melena, which is often caused by bleeding in the upper gastrointestinal tract.

When to See a Doctor

If your black stool is accompanied by other symptoms such as abdominal pain, dizziness, weakness, or weight loss, it could signal a more serious problem. Seek medical attention immediately. Likewise, if the black color persists despite dietary changes or if there’s a tar-like consistency, it’s essential to consult a healthcare professional to rule out bleeding or other underlying conditions.
