Gastrointestinal bleeding is a potential sign of an underlying issue in the digestive system, ranging from mild irritation to serious gastrointestinal diseases. The bleeding can occur anywhere along the GI tract, from the oesophagus to the rectum, and it may not always be visible. In some cases, it can signal a medical emergency.
Understanding a gastrointestinal bleed symptoms, causes, and when to seek medical help is essential. Early gastrointestinal bleeding diagnosis and proper care can prevent complications.
Gastrointestinal bleeding refers to any form of blood loss that originates from the digestive tract. The bleeding can occur from the oesophagus, stomach, or the first part of the small intestine, (which is the upper GI bleeding) or from the colon, rectum, or anus (which is the lower GI bleeding).
The bleeding can be acute (sudden and severe) or chronic (slow and long-lasting), and the symptoms may vary based on the source and severity of the bleed. While some bleeding is visible—such as vomiting blood or passing black stools, other cases may only be detected through lab tests or endoscopic exams.
Symptoms can range from subtle to severe, depending on where and how much bleeding is occurring. Key gastrointestinal bleeding symptoms include:
This may appear as bright red blood or have a dark, coffee-ground appearance, indicating bleeding from the upper GI tract.
Dark, sticky stools are a sign of digested blood from the stomach or upper intestines.
Bright red blood in or on the stool usually indicates lower GI bleeding, often from the colon or rectum.
Pain may be present if the bleeding is due to ulcers, inflammation, or other gastrointestinal conditions.
Chronic blood loss can lead to anaemia, which causes fatigue, dizziness, and general weakness.
These signs may indicate significant blood loss and require urgent medical attention.
If you notice any of these symptoms, it’s important to consult a healthcare professional immediately. Gastroenterologists can conduct a thorough evaluation to identify the source and severity of bleeding.
A wide range of conditions can lead to bleeding in the GI tract. Here are the most common gastrointestinal bleeding causes:
These are open sores that form in the stomach lining or the upper part of the small intestine. Often caused by a bacterial infection (H. pylori) or taking painkillers like NSAIDs for a long time.
This is when the stomach lining gets irritated or inflamed, usually from alcohol, stress, or certain medicines. It can lead to small areas of bleeding.
These are swollen veins in the lower part of the rectum or anus. They can burst and bleed during bowel movements, especially if you’re straining.
These are tiny cuts or tears in the skin around the anus, often caused by hard stools or constipation. They can be painful and cause bright red bleeding.
This happens when small pouches form in the wall of the colon. Sometimes they get irritated or bleed without warning.
These are growths inside the colon or rectum. Some may bleed, and doctors usually check them with a test called a colonoscopy.
These are enlarged veins in the food pipe (oesophagus), often due to liver problems. If they burst, they can cause serious and heavy bleeding.
Diagnosing the source and cause of bleeding often involves a combination of physical exams, lab tests, and imaging procedures. Common methods for gastrointestinal bleeding diagnosis include:
A flexible tube with a camera is used to examine the upper GI tract and detect ulcers, inflammation, or tumours.
Used to inspect the colon and rectum for polyps, cancer, or diverticula.
These tests assess haemoglobin levels and help detect anaemia caused by chronic blood loss.
CT scans, angiography, or capsule endoscopy may be used when endoscopy or colonoscopy cannot locate the source.
Prompt diagnosis is essential for timely gastrointestinal bleeding treatment and to prevent recurrence.
Gastrointestinal bleeding treatment depends on the cause, location, and severity of the bleeding. Common treatments include:
During endoscopy, bleeding can be stopped using clips, heat probes, or medication injections.
Proton pump inhibitors (PPIs), antibiotics for infections, or laxatives for constipation may be prescribed based on the diagnosis.
Avoiding alcohol, NSAIDs, and spicy foods, and increasing fibre intake can reduce the risk of future bleeding episodes.
In severe or recurrent cases, surgical intervention may be required to remove bleeding lesions or repair damaged tissue.

Gastrointestinal bleeding is a serious symptom that should never be ignored. From mild issues like constipation and haemorrhoids to more severe conditions like ulcers or colon cancer, bleeding in the GI tract often signals a deeper problem.
