What should you know about black stool causes and treatment?

Iron products and dark foods can change stool colour without causing bleeding. Black, sticky, tar-like stool is more concerning for digested blood from the upper digestive tract. Gastritis can irritate the stomach lining, while a peptic ulcer can bleed; Helicobacter pylori infection may contribute to stomach inflammation or ulcer disease. The right treatment depends on the cause, the amount of bleeding, your symptoms, and the medicines you take. Colour alone cannot settle the diagnosis.

Seek prompt medical advice for new or unexplained black stool. A clinician may review your history, examine you, and arrange tests to look for blood loss or a digestive source. Treatment may involve stopping or changing a contributing medicine under supervision, reducing stomach irritation, treating Helicobacter pylori infection when confirmed, or treating an ulcer or gastritis. Do not start antibiotics or stop prescribed medicines without specific advice.

Use emergency services for black stool with fainting, dizziness, severe weakness, confusion, cold clammy skin, severe abdominal pain, or vomiting blood or coffee-ground material. These features can accompany significant digestive bleeding. Even without red flags, arrange timely advice if the stool remains black, returns after a suspected food cause, or has a tar-like texture.

Ask what cause is most relevant to your symptoms, whether any medicine should be changed, what tests are planned, and how quickly improvement should occur. Ask how gastritis, peptic ulcer disease, or Helicobacter pylori infection would alter treatment and when to seek help again.
