Gastro Intestinal Bleeding
What is gastro-intestinal (GI) bleeding?
Gastrointestinal (GI) bleeding is when bleeding occurs in any part of the gastrointestinal tract. The GI tract includes your esophagus, stomach, small intestine, large intestine (colon), rectum, and anus. GI bleeding itself is not a disease, but a symptom of any number of conditions.
What are the causes of gastro-intestinal bleeding?
The causes and risk factors for gastrointestinal (GI) bleeding are classified into upper or lower, depending on their location in the GI tract.
How is gastro-intestinal bleeding diagnosed?
GI bleeding can usually be diagnosed by a digital rectal exam, an endoscopy or colonoscopy, and lab tests.
Causes of upper GI bleeding include
- peptic ulcers,
- gastritis (bleeding in the stomach),
- esophageal varices due to liver cirrhosis cancers,
- and inflammation of the GI lining from ingested materials.
What are the signs and symptoms of gastrointestinal (GI) bleeding?
Acute gastrointestinal bleeding first will appear as vomiting of blood, bloody bowel movements, or black, tarry stools. Vomited blood from bleeding in the stomach may look like “coffee grounds.” Symptoms associated with blood loss can include:
- Fatigue
- Weakness
- Shortness of breath
- Abdominal pain
- Pale appearance
- Vomiting of blood usually originates from an upper GI source.
- Bright red or maroon stool can be from either a lower GI source or from brisk bleeding from an upper GI source.
- Long-term GI bleeding may go unnoticed or may cause fatigue, anemia, black stools, or a positive test for microscopic blood.
How is gastro-intestinal bleeding treated?
Treatment for GI bleeding usually includes hospitalization because blood pressure may drop and heart rate may increase and this needs to be stabilized. In some cases, IV fluids or blood transfusions are needed, and surgery may be required. The prognosis for a person with GI bleeding depends upon the cause and location of the bleeding, how bad the bleed is when the person sees the doctor, and any underlying medical conditions that may affect the patient’s recovery.
