What causes vomiting blood?
Vomiting blood can result from many different conditions. Common causes of gastrointestinal bleeding include inflammation, infection, and underlying disease processes such as malignancy.
Vomiting blood may be caused by conditions in the esophagus such as esophagitis (inflammation of the esophagus) or esophageal varices (swollen veins in the esophagus). Sometimes, a severe nosebleed can result in vomiting blood if the blood flows into the back of the throat and causes retching. Vomiting blood may also occur from internal injuries to the organs in the digestive tract following trauma.
