When patients with cirrhosis experience vomiting blood, it generally indicates that the cirrhosis has entered the decompensated phase, which is a late-stage symptom of cirrhosis. The main reason for vomiting blood may likely be that the cirrhosis has caused a peptic ulcer, or rupture and bleeding of esophageal and gastric varices due to cirrhosis, or bleeding caused by portal hypertensive gastropathy resulting from cirrhosis. If vomiting blood occurs with cirrhosis, the amount of bleeding is generally very large. At this time, it is necessary to go to the hospital as soon as possible for a complete gastroscopy. When necessary, endoscopic treatment may be needed to stop the bleeding.
