Patients who vomit and pull blood are manifestations of gastrointestinal bleeding, which is more likely to be considered a disease of the digestive system itself in the first place, and may be associated with other and systemic diseases.
Gastrointestinal bleeding is divided into upper and lower gastrointestinal bleeding. In the case of upper gastrointestinal bleeding, diseases such as erosive gastritis, peptic ulcer, and malignant tumors of the stomach and esophagus may be considered. In more severe cases, patients will show blood spitting, and small amounts of bleeding will usually show blood in the stool, which will mostly show tarry symptoms. Patients may be accompanied by some clinical manifestations such as gastric distension, stomach pain, heartburn, acid reflux, bad breath, etc. The diagnosis needs to be confirmed by gastroscopy and other examinations in the gastroenterology department of a regular hospital.
Lower gastrointestinal bleeding can be seen in anal diseases such as hemorrhoids and anal fissures. In addition, malignant diseases such as enteritis, bacillary dysentery, intestinal polyps, rectal cancer, and colon cancer can also cause blood in the stool. The lower gastrointestinal bleeding is usually predominantly hemorrhagic and rarely results in vomiting of blood.
Other diseases such as pancreatic cancer, hepatocellular carcinoma, cirrhosis, thoracic aortic aneurysm, and other lesions in the adjacent digestive organs can also cause gastrointestinal bleeding. Systemic diseases such as epidemic hemorrhagic fever, coagulation disorders, and uremia can cause GI bleeding. The cause of the bleeding needs to be promptly identified and then treated symptomatically.
