Black stools, medically known as melena, are not a normal bowel finding. In most cases, black stools indicate bleeding in the upper digestive tract, such as the stomach or upper intestine. Understanding black stools causes and treatment is important because early diagnosis can prevent serious complications.
What Are Black Stools?
Black stools appear dark, tarry, sticky, and foul-smelling. This happens when blood from the stomach or upper intestine gets digested as it passes through the gut. Unlike normal dark stools caused by food, melena usually indicates an underlying medical problem that requires attention.
Why Do Black Stools Occur?
The most common black stools causes include:
1. Stomach Ulcers
Open sores in the stomach lining can bleed slowly, leading to black stools. Ulcers are often caused by H. pylori infection or excessive painkiller use.
2. Gastritis
Inflammation of the stomach lining may cause bleeding, especially in people who consume alcohol, smoke, or take NSAIDs regularly.
3. Painkiller-Related Bleeding
Long-term use of painkillers such as ibuprofen, aspirin, or diclofenac can damage the stomach lining and cause internal bleeding.
4. Liver Disease
Advanced liver conditions can lead to variceal bleeding (swollen veins in the food pipe), which may present as black stools.
5. Upper Intestinal Bleeding
Bleeding from the duodenum or upper small intestine is another significant cause of melena.
Symptoms That May Occur Along With Black Stools
People experiencing black stools may also notice:
-
Fatigue or weakness
-
Dizziness or fainting
-
Abdominal pain
-
Vomiting blood (in severe cases)
-
Pale skin or breathlessness
These symptoms suggest significant blood loss and require urgent evaluation.
When Are Black Stools an Emergency?
Black stools should never be ignored, especially if:
-
They persist for more than one day
-
You feel weak or dizzy
-
You have a history of ulcers, liver disease, or long-term painkiller use
Early medical evaluation helps identify the exact cause and prevents complications like anemia or shock.
Diagnosis of Black Stools
To determine black stools causes and treatment, doctors may recommend:
-
Blood tests to check hemoglobin levels
-
Stool tests
-
Upper GI endoscopy to identify the bleeding source
-
Ultrasound or CT scan if liver disease is suspected
Treatment Options for Black Stools
Treatment depends on the underlying cause and may include:
-
Medications to heal ulcers and gastritis
-
Stopping or modifying painkiller usage
-
Antibiotics for H. pylori infection
-
Endoscopic procedures to stop bleeding
-
Specialized care for liver-related bleeding
Early treatment ensures faster recovery and reduces risk.
How to Prevent Black Stools
Preventive steps include:
-
Avoid unnecessary painkiller use
-
Limit alcohol consumption
-
Eat balanced meals
-
Manage stress
-
Seek early treatment for stomach discomfort
