In more severe cases of chronic or adễ thương bleeding, symptoms may include signs of anemia, such as weakness, pallor, dizziness, shortness of breath or angina. More obvious bleeding may present with hematemesis (bloody vomit), which may either be red or dark và coffee-lượt thích in appearance.

Blood in the stool could either be bright red, burgundy và clotted, or blachồng và tarry in appearance, depending on the location of the bleeding source. A blachồng, tarry stool (melena) often indicates an upper GI source of bleeding although it could originate from the small intestine or right colon. Other causes of a blaông xã stool might include iron or ingestion of bismuth (Pepto-Bismol). Hematochezia, or bright red blood can be mixed in with the stool or after the bowel movement và usually signifies a bleeding source cthua thảm to lớn the rectal opening.

It allows the doctor lớn examine the esophagus, stomach và duodenum for any potential bleeding sites. If a site is detected, therapeutic measures can be used lớn control the bleeding. For example, a bleeding ulcer may be controlled with use of cautery, laser photo therapy, injection therapy or tamponade.

If the bleeding is suspected khổng lồ be in the lower GI tract or colon, then a colonoscopy is usually performed. In a colonoscopy, a video colonoscope is passed through the rectum and across the entire colon, while the patient is sedated.

Other diagnostic methods for detecting a bleeding source might include a nuclear bleeding scan, angiography, or barium GI studies.

In the case of chronic low-grade or occult bleeding which may result in anemia, the work-up khổng lồ discover the source of the bleeding is usually done on an outpatient basis. Generally this consists of a colonoscopy and/or upper endoscopy to look for any potential sources of chronic blood loss.

How is GI bleeding treated?

If GI bleeding is very active or severe in nature, it may require hospitalization. Shochồng can occur when blood loss approaches approximately 40 percent of blood volume. If there is evidence of hypotension (low blood pressure) or a fast heart rate, dizziness, or light-headedness, then treatment would include IV fluids and monitoring of the blood count, with blood transfusions given, if necessary.

While in the hospital, the patient will continue lớn be monitored closely and certain medications will be employed in an attempt khổng lồ stop the bleeding. In addition, diagnostic tests are performed.

Esophageal varices, or varicose veins, are usually the result of underlying chronic liver disease lượt thích cirrhosis & these can often bleed very briskly. A tear at the junction of the esophagus & stomach sometimes also occurs as a result of repeated vomiting or retching.
