There are two possibilities when a patient vomits too much and ends up vomiting with blood. The first one, violent vomiting causes the cardia mucosa to tear, which requires an electronic gastroscopy to clarify. After diagnosis, the first thing to do is to control the vomiting, which can be treated with Gastrofacial or 654-2 antiemetic. If this situation is excluded, it is mostly considered that the mucous membrane of the stomach, esophagus and even throat is damaged by the stomach acid from vomiting, which needs to be treated with drugs to inhibit stomach acid. Generally, the blood vomited is mostly blood, which can be improved after antiemetic and stomach acid inhibiting drugs are used. If you vomit blood clots, to exclude the rupture of blood vessels in the stomach, you need to do electronic gastroscopy to clarify, and under the electronic gastroscope to perform hemostatic treatment.
