What should you know about black wet stool?

Stool that is black, sticky, shiny, or tar-like can occur when blood has been digested higher in the digestive tract. Irritation of the stomach lining, including gastritis, or a peptic ulcer can cause this type of bleeding. Helicobacter Pylori Infection is one possible contributor to stomach or ulcer problems. Dark stool can also follow iron tablets, bismuth-containing medicines, or strongly coloured foods, but appearance alone cannot safely identify the cause.

Note whether the change happened once or repeatedly, and whether you have upper abdominal discomfort, vomiting, faintness, unusual tiredness, or a racing heartbeat. These details help a clinician judge how urgently you need assessment.

If the stool is genuinely black and tarry, contact a healthcare professional promptly rather than waiting for several bowel movements to pass. Do not stop prescribed medicines without advice, but tell the clinician about painkillers, blood thinners, iron, and stomach remedies. Keep a note of the colour, texture, timing, and any recent foods or medicines. If you feel faint, lie down safely and avoid driving yourself.

Seek emergency help for black stool with vomiting blood or material resembling coffee grounds, severe or worsening abdominal pain, collapse, confusion, marked weakness, breathlessness, or cold clammy skin. Urgent assessment is also sensible when black stools recur or are accompanied by dizziness, because digestive bleeding can worsen without dramatic pain.

Ask whether your medicines or supplements could darken stool, whether testing for bleeding or anaemia is needed, and whether gastritis, Helicobacter Pylori Infection, or a peptic ulcer should be considered. Mention any previous ulcers, alcohol use, recent illness, and changes in bowel habit.
