Very dark brown stool that is almost black

Brown stool can deepen after dark foods or changes in digestion. Stool that is truly black, shiny, sticky, and difficult to flush is different: it may contain digested blood from the stomach or upper intestine. Gastritis and peptic ulcer are possible sources, and Helicobacter Pylori Infection can be associated with stomach irritation and ulcer formation. A photo, description of texture, and list of recent medicines can help a clinician judge the change, although these details do not replace an examination.

Record what you ate and any iron or bismuth-containing product you used. Check whether the colour returns toward your usual brown after the suspected trigger has passed, but do not dismiss a repeated black or tarry bowel movement. Contact a healthcare professional for advice if the cause is unclear. Mention aspirin, anti-inflammatory painkillers, steroids, or blood thinners, since these medicines can affect digestive bleeding risk.

Get urgent help if the dark stool comes with faintness, racing heartbeat, unusual tiredness, pale or clammy skin, worsening stomach pain, vomiting blood, or coffee-ground vomit. These symptoms may indicate blood loss. Same-day advice is sensible for recurrent black stool, especially if you have a history of ulcers or take medicine that reduces clotting.

Ask whether the stool needs a blood count or stool test, whether an ulcer or gastritis should be considered, and whether Helicobacter Pylori Infection testing fits your symptoms. Explain its colour, shine, texture, smell, timing, and any associated pain or nausea.
