Black Stool in Old Age

Black stool that is sticky or tar-like can result from blood being digested before it leaves the body. Possible causes include gastritis, a peptic ulcer, or Helicobacter Pylori Infection. Iron, bismuth, and dark foods can produce a harmless colour change, but appearance can be difficult to judge under bathroom lighting. Age alone does not identify the cause; medicines, previous stomach problems, alcohol use, and symptoms such as dizziness or vomiting add useful context.

Seek medical advice promptly for a new unexplained black stool, even if the person feels reasonably well. Record when it began, whether it recurred, and whether it was sticky, unusually smelly, or difficult to flush. Prepare every medicine and supplement name, particularly blood thinners, aspirin, anti-inflammatory pain medicines, and iron. Do not stop regular prescriptions without guidance. A clinician can decide whether examination, blood testing, or further digestive assessment is appropriate.

Go to emergency care for fainting, confusion, severe weakness, breathlessness, chest discomfort, cold clammy skin, vomiting blood, severe abdominal pain, or repeated tarry stools. New pallor, a racing heartbeat, very little urine, or inability to walk safely should also be treated as urgent. Someone who feels faint should lie safely while help is arranged and should not drive.

Ask whether the stool could be related to gastritis, Helicobacter Pylori Infection, or a peptic ulcer; whether any medicine should be reviewed; and which symptoms require immediate hospital care. Mention appetite, nausea, abdominal discomfort, previous ulcers, dizziness, falls, and any recent change in medicines.
