Dark Stool Insights: Symptoms, Possible Causes, and When to Seek Help
While black or dark stools are not always a sign of serious illness, understanding their origin is important. Iron supplements may cause stool to darken, and gastrointestinal bleeding or injuries can also produce similar discoloration. Common signs include tar-like, dark stool, often alongside other symptoms depending on the cause. Though many reasons are harmless, prompt medical assessment is vital to exclude serious conditions such as ulcers, bleeding, or tumors. Always see a healthcare provider if dark stool appears.

Persistent bleeding might be a sign of colorectal cancer, requiring immediate medical review.

Less severe causes include hemorrhoids or swollen veins that bleed under pressure.

Dietary influences on stool color

Foods such as black licorice, blueberries, dark chocolate cookies, beets, and red gelatin can temporarily darken stool.
