Gastro-intestinal Bleeding

Gastro-intestinal Bleeding
Gastrointestinal (GI) bleeding refers to any form of bleeding that occurs in the digestive tract, ranging from the mouth to the rectum. It can manifest in various forms, from minor bleeding that produces small amounts of blood in the stool to severe bleeding that requires immediate medical attention. Here's a detailed overview:
Symptoms
Black, tarry stools (melena)
This indicates bleeding in the upper GI tract, where blood is partially digested.
Bright red or maroon-colored stools
Some individuals may experience nausea, and vomiting may occur, especially if the ulcer is severe.
Vomiting blood (hematemesis)
Blood in vomit is often a sign of significant upper GI bleeding.
Weakness and fatigue
Loss of blood can lead to anemia and associated symptoms like weakness, fatigue, and lightheadedness.
Abdominal pain or discomfort
Depending on the cause and location of the bleeding, abdominal pain may occur.
Diagnosis
Endoscopy:
A flexible tube with a camera is inserted through the mouth or rectum to directly visualize the GI tract and identify the source of bleeding.
Imaging tests:
CT scans or angiography may be used to locate the source of bleeding if endoscopy is inconclusive.
Blood tests:
These can help determine the extent of blood loss and assess for anemia.
Stool tests
Occult blood tests can detect small amounts of blood in the stool, which may not be visible to the naked eye.
Treatment
Fluid resuscitation
Intravenous fluids and blood transfusions may be necessary to replace lost blood volume.
Medications
Proton pump inhibitors (PPIs), antibiotics (if bacterial infection is suspected), and medications to stop bleeding (e.g., vasopressin) may be used.
Endoscopic therapy
Techniques such as cauterization, clipping, or injection of medications can be used to stop bleeding during endoscopy.
Surgery
In severe cases or if endoscopic methods fail, surgery may be required to repair the source of bleeding.
Causes
Peptic ulcers:
Ulcers in the stomach or small intestine are a common cause of GI bleeding.
Esophageal varices:
These are enlarged veins in the esophagus, often due to liver disease, which can rupture and cause significant bleeding.
Mallory-Weiss tears:
Tears in the lining of the esophagus, usually caused by severe vomiting or retching.
Gastritis:
Inflammation of the stomach lining can lead to erosions and bleeding.
Diverticulosis:
Small pouches that develop in the colon can sometimes bleed.
Colorectal cancer:
Cancerous growths in the colon or rectum may bleed.
Inflammatory bowel disease (IBD):
Conditions like Crohn's disease or ulcerative colitis can cause inflammation and bleeding in the digestive tract.
Complications
Hemorrhagic shock
Severe bleeding can lead to dangerously low blood pressure and organ damage.
Anemia
Chronic or severe bleeding can result in iron deficiency anemia.
Perforation
Some causes of GI bleeding, such as severe ulcers, can lead to perforation of the digestive tract.
