Black Stool: Causes, Symptoms & When to See a Doctor

A black, tarry stool is typically a sign of upper gastrointestinal bleeding. This type of bleeding can occur from a number of different conditions, including:

* Esophageal variceal bleeding: This occurs when the veins in the esophagus become enlarged and burst. This can be caused by a number of conditions, including liver cirrhosis and portal hypertension.

* Gastric ulcer bleeding: This occurs when an ulcer in the stomach bleeds. This can be caused by a number of factors, including NSAID use, alcohol abuse, and infection with H. pylori bacteria.

* Duodenal ulcer bleeding: This occurs when an ulcer in the duodenum (the first part of the small intestine) bleeds. This can be caused by a number of factors, including NSAID use, alcohol abuse, and infection with H. pylori bacteria.

Black, tarry stools are typically accompanied by other symptoms, such as:

* Abdominal pain

* Nausea

* Vomiting

* Fatigue

* Weakness

* Lightheadedness

* Dizziness

* Confusion

If you experience any of these symptoms, it is important to see a doctor right away. Black, tarry stools can be a sign of a serious medical condition that requires treatment.

Here are some tips for preventing upper gastrointestinal bleeding:

* Avoid NSAIDs if you have a history of stomach ulcers.

* Drink alcohol in moderation.
