Colonoscopy - Gastrointestinal Bleeding (460 words) |
 | Gastrointestinal bleeding or gastrointestinal hemorrhage describes every form of hemorrhage (loss of blood) in the gastrointestinal tract, from the pharynx to the rectum. |
| Gastrointestinal bleeding can be roughly divided into two clinical syndromes: upper gastrointestinal bleeding (from a source between the pharynx and the ligament of Treitz) and lower gastrointestinal bleeding. |
| Gastrointestinal bleeding can range from microscopic bleeding, where the amount of blood is so small that it can only be detected by laboratory testing (in the form of iron deficiency anemia), to massive bleeding where pure blood is passed and hypovolemia and shock may develop, risking death. |
