Vomiting blood is a backward flowing (regurgitation) of blood through the upper gastrointestinal (GI) tract. The GI tract includes the small intestine, stomach, mouth, throat, and esophagus (the tube that moves food and secretions from mouth to stomach).
Considerations
Vomiting of blood results after there is upper gastrointestinal bleeding. This condition can sometimes be difficult to distinguish from coughing up blood (from the lung) or a nosebleed (bloody post-nasal drainage).
Conditions that cause blood to be vomited can also cause blood in the stool.
Common Causes
There are several reasons why someone may vomit blood. For example, vomiting that is very forceful or continues for a very long time may cause a tear in the small blood vessels of the throat or the esophagus, producing streaks of blood in the vomit.
Other causes may include:
Bleeding ulcer located in the stomach, duodenum, or esophagus
Bleeding esophageal varices
Defects in the blood vessels of the GI tract
Esophagitis
Gastritis
Gastroenteritis
Irritation or erosion of the lining of the esophagus or stomach
Swallowing blood (for example, swallowed after a nosebleed)
Tumors of the stomach or esophagus
