Black stool treatment: home remedies and safe next steps

Stool may look dark after iron, bismuth-containing products, or deeply pigmented foods. Melena is different: it is often jet black, sticky, and unusually strong-smelling because blood has been changed as it travels through the digestive system. Possible causes include gastritis, a peptic ulcer, or Helicobacter pylori infection. Black colour alone cannot identify the cause.

If the change is unexplained, contact a clinician promptly and describe the colour, texture, smell, and when it began. List every medicine and supplement, including iron and pain relievers. Do not take leftover medicines or add anti-inflammatory painkillers for stomach discomfort. Keep hydrated if you feel well, but fluids and bland food will not stop digestive bleeding. A clinician may examine you, review medicines, and arrange tests based on your symptoms.

Seek emergency care for black stool with dizziness, fainting, unusual weakness, confusion, shortness of breath, severe abdominal pain, vomiting blood, or vomit that looks like coffee grounds. Urgent assessment is also needed if stools remain black or become frequent, especially when you have a history of ulcers or take blood-thinning medicine. Do not drive yourself if you feel faint.

Ask whether your medicines could explain the colour, whether testing for Helicobacter pylori is suitable, and whether your symptoms fit gastritis or a peptic ulcer. Ask which pain relievers to avoid and what changes should prompt immediate reassessment.
