Tarry

Tarry refers to a dark, sticky substance that is often associated with feces or stool. It is typically indicative of gastrointestinal bleeding, which can be a serious medical condition requiring immediate attention.

Causes

Tarry stools, also known as melena, can be caused by a variety of factors. These include:

• Peptic ulcer: This is a sore that develops on the lining of the stomach, upper small intestine or esophagus. It is one of the most common causes of tarry stools.
• Gastritis: This is an inflammation, irritation, or erosion of the lining of the stomach. It can be acute or chronic.
• Mallory-Weiss syndrome: This is a condition marked by tears in the lining of the lower part of the esophagus. It is often associated with severe vomiting.
• Esophageal varices: These are abnormal, enlarged veins in the lower part of the esophagus. They are often associated with serious liver diseases.

Symptoms

In addition to tarry stools, other symptoms may be present, including:

• Abdominal pain
• Nausea
• Vomiting blood
• Weakness
• Dizziness
• Shortness of breath

Diagnosis

Diagnosis of the cause of tarry stools typically involves a physical examination and a review of the patient's medical history. Additional tests may include:

• Blood test
• Stool test
• Endoscopy
• Colonoscopy

Treatment

Treatment for tarry stools depends on the underlying cause. It may include medications to reduce stomach acid or antibiotics to treat infections. In severe cases, surgery may be required.
