What should you know about black but not tarry stool?

Bleeding higher in the digestive tract is often digested, which can make stool black and sticky. Stool that is simply dark but formed and not sticky is more often linked with something consumed, such as dark foods, iron, or bismuth-containing medicine, although appearance cannot confirm the cause.

Gastritis, a peptic ulcer, and Helicobacter Pylori infection can all be associated with upper digestive symptoms or bleeding. A dark stool does not establish any of these conditions, and many people with them have other symptoms or no obvious change in stool.

Review what you ate and which medicines or supplements you started recently. Keep track of whether the colour returns to normal, whether the stool becomes sticky, and whether you develop pain, nausea, or unusual tiredness.

Contact a clinician if the change persists, recurs without a clear explanation, or occurs with digestive symptoms. Bring the names of your medicines and supplements. Do not discontinue prescribed medicine on your own.

Get emergency help if dark stool becomes tar-like or is accompanied by faintness, confusion, severe abdominal pain, vomiting blood or coffee-ground material, breathlessness, or profound weakness. A person who feels acutely unwell should not drive themselves.

Ask whether the colour could be explained by a medicine or food, whether testing for digestive blood is appropriate, and what symptoms should trigger emergency care. Explain the stool texture and any recent change in appetite or bowel habit.
