Vomiting And Defecating Blood
Bleeding From the Digestive Tract
Bleeding may occur anywhere along the digestive tract, from the mouth to the anus. Blood may be visible in vomit (hematemesis). When blood is vomited, it may be bright red if bleeding is brisk and ongoing. Alternatively, vomited blood may have the appearance of coffee grounds if bleeding has slowed or stopped, due to the partial digestion of the blood by acid in the stomach.
Blood may also be passed from the rectum, either as black tarry stools (melena) or as bright red blood (hematochezia).
Melena is more likely when bleeding comes from the esophagus, stomach, or small intestine. The black color of melena results from blood that has been exposed for several hours to stomach acid and enzymes and to bacteria that normally reside in the large intestine. Hematochezia is more likely when bleeding comes from the large intestine, although it can result from very rapid bleeding from the upper portions of the digestive tract as well.
Bleeding from the digestive tract can have many causes, including peptic ulcers; abnormal connections between the arteries and veins of the intestines (arteriovenous malformations); dilated veins in the esophagus (esophageal varices); irritation from use of certain drugs, such as aspirinSome Trade Names ECOTRINASPERGUMand other nonsteroidal anti-inflammatory drugs (NSAIDs); inflammatory bowel disease; and cancer of the digestive system.
Serious and sudden blood loss may be accompanied by a rapid pulse rate, low blood pressure, and reduced urine flow. A person may also have cold, clammy hands and feet. The decreased flow of blood to the brain that can occur with severe bleeding of the digestive tract may lead to confusion, disorientation, sleepiness, and even extremely low blood pressure (shock).
