Causes of bleeding in the gastrointestinal (GI) tract

It Can Be Colorectal Bleeding

Colorectal bleeding is the passage of blood through the anus. The bleeding will appear as a bright red or maroon color in the stool. Sometimes the bleeding may not be visible to the human eye. It may not be painful, but symptoms like diarrhoeaand abdominal cramps may follow. The origin of the bleeding can be determined by history and physical examination. It can also be screened though, anoscopy, flexible sigmoidoscopy, colonoscopy radionuclide scans, visceral angiograms, flexible endoscopy, capsule endoscopy of the small intestine, and blood testing.

Diverticular Bleeding

Diverticular bleeding happens when a diverticulum erodes into the penetrating artery at its base. It is a painless rectal bleeding and since it happens in the colon, the stool is bright red or maroon. Generally, the bleeding is mild and resolves itself along with the bowel movement.However, brisk bleeding can be life threatening and needs immediate medical attention. It requires rigorous attempts to locate the site of bleeding and stop it. It can be done through colonoscopyor angiography. If bleeding persists surgery may be required.

Colonic Polyps Bleeding

Colonic polyps are caused by cell growth and division before new cells are needed.Bleeding occurs when there is excess growth ofcolonic polyps in the colon area. There could be blood in the stool or rectal bleeding. Regular screening tests are required to detect any existing polyps. If polyps are detected in early stages they can be removed during a colonoscopy.

Other causes

Bleeding in the gastrointestinal (GI) tract may be caused by other conditions, including hemorrhoids, peptic ulcers, tears or inflammation in the esophagus, ulcerative colitis, Crohn's disease,and others.
