Hematemesis (American English) or haematemesis (International English) is the vomiting of fresh red blood. The source is generally the upper gastrointestinal tract. Patients can easily confuse it with hemoptysis (coughing up blood), although the former is more common.

A history of excessive alcohol use or liver disease
Any esophogastric symptoms, such as nausea or vomiting
Brown or black blood
Blood that looks like coffee grounds
Dark colored, tar like stools (a condition known as melena)
Causes
Causes can be:
Prolonged and vigorous retching (may cause a tear in the small blood vessels of the throat or the esophagus, producing streaks of blood in the vomit)
Irritation or erosion of the lining of the esophagus or stomach
Bleeding ulcer located in the stomach, duodenum, or esophagus
Ingested blood (for example, swallowed after a nosebleed)
Vomiting of ingested blood after hemorrhage in the oral cavity, nose or throat
Vascular malfunctions of the gastrointestinal tract
Tumors of the stomach or esophagus
Esophagitis
Gastroenteritis
Gastritis
Mallory-Weiss syndrome (esophageal tear)
Esophageal varices
