Gastrointestinal Bleeding

Gastrointestinal (GI) bleeding, also known as gastrointestinal hemorrhage, is a condition characterized by bleeding in the digestive tract. The bleeding can occur anywhere along the GI tract, from the mouth to the anus.

Causes of Gastrointestinal Bleeding

• Peptic ulcers: Sores in the lining of the stomach or small intestine that can bleed.
• Gastritis: Inflammation of the stomach lining, which can cause bleeding.
• Esophagitis: Inflammation of the esophagus, which can cause bleeding.
• Diverticulosis: A condition in which small pouches form in the wall of the colon, which can bleed.
• Colitis: Inflammation of the colon, which can cause bleeding.
• Cancer: Tumors in the GI tract can cause bleeding.
• Vascular malformations: Abnormal blood vessels in the GI tract that can bleed.
• Trauma: Injury to the GI tract, such as from a car accident or a fall.

Symptoms of Gastrointestinal Bleeding

• Vomiting blood (hematemesis)
• Black, tarry stools (melena)
• Blood in the stool (hematochezia)
• Abdominal pain
• Nausea and vomiting
• Dizziness or lightheadedness
• Fainting (syncope)

Diagnosis of Gastrointestinal Bleeding

Diagnosis is typically made using a combination of the following tests:

• Endoscopy: A procedure in which a flexible tube with a camera is inserted through the mouth or rectum to visualize the inside of the GI tract.
• Colonoscopy: A procedure in which a flexible tube with a camera is inserted through the rectum to visualize the inside of the colon.
• Upper GI series: A test in which a patient swallows a barium solution and X-rays are taken to visualize the upper GI tract.
• CT scan: A test that uses X-rays and computer technology to produce detailed images of the inside of the body.
• Blood tests: To check for anemia, blood clotting disorders, and other conditions that may be contributing to the bleeding.

Treatment of Gastrointestinal Bleeding

Treatment depends on the cause and severity of the bleeding. It may include:

• Endoscopic treatments: Such as cauterization, clipping, or banding to stop the bleeding.
• Medications: To reduce acid production in the stomach, protect the stomach lining, or promote blood clotting.
• Blood transfusions: To replace lost blood and prevent anemia.
• Surgery: In severe cases, surgery may be necessary to repair or remove the bleeding site.

Complications of Gastrointestinal Bleeding

Untreated GI bleeding can lead to:

• Anemia: A condition in which the body does not have enough red blood cells.
• Shock: A life-threatening condition that occurs when the body does not have enough blood flow.
• Organ failure: Such as kidney or liver failure, due to inadequate blood flow.
• Death: In severe cases, GI bleeding can be fatal if left untreated.
