GI Bleeding

Gastrointestinal (GI) bleeding is when bleeding occurs in any part of the gastrointestinal tract. GI bleeding itself is not a disease, but a symptom of any number of disorders. The blood often appears in stool or vomit, but isn’t always noticeable. The level of bleeding can range from mild to life-threatening.

The causes of gastrointestinal (GI) bleeding are divided into upper or lower, depending on their location in the GI tract:

  • Upper GI bleeding: includes the esophagus, stomach, and first part of the small intestine.
  • Lower GI bleeding: includes most of the small intestine, large intestine or bowels, rectum and anus.

Noticeable signs of GI bleeding include:

  • Dark, tarry stools
  • Larger amounts of blood passed from the rectum
  • Small amounts of blood in the toilet bowl, on toilet paper, or in streaks on stool (feces)
  • Vomiting blood
  • May experience abdominal pain

GI bleeding may be due to conditions that are not serious, including:

  • Anal fissure
  • Hemorrhoids

GI bleeding may also be a sign of more serious diseases and conditions. These may include cancers of the GI tract such as:

  • Cancer of the colon
  • Cancer of the small intestine
  • Cancer of the stomach
  • Intestinal polyps (a pre-cancerous condition)

Other causes of GI bleeding may include:

  • Abnormal blood vessels in the lining of the intestines (also called angiodysplasia)
  • Bleeding diverticulum, or diverticulosis
  • Crohn’s disease or ulcerative colitis
  • Esophageal varices
  • Esophagitis
  • Gastric (stomach) ulcer
  • Intussusception (bowel telescoped on itself)
  • Mallory-Weiss tear
  • Meckel’s diverticulum
  • Radiation injury to the bowel

GI bleeding can be diagnosed by a digital rectal exam, an endoscopy or colonoscopy, and lab tests. The prognosis for a patient with GI bleeding depends upon the cause and location of the bleeding, amount of bleeding, and any underlying medical conditions that may affect the patient’s recovery.
