After stomach bleeding, you need to see the degree of bleeding. If the amount of bleeding is small, below 200 ml, there is generally no bleeding. The main manifestation of bleeding is black stool or stool occult blood positive. However, if the patient's bleeding amount reaches more than 200 ml in a short time, it will lead to frequent vomiting of blood because of the stimulation of blood to the gastrointestinal tract. At this time, patients are usually accompanied by systemic blood volume insufficiency, even hemorrhagic shock, and common clinical manifestations such as palpitation, fatigue, sweating, dizziness, black sputum and so on.

Hematemesis refers to the patient vomiting blood, which is mostly caused by acute upper gastrointestinal bleeding, but it may also be a symptom caused by some systemic diseases. First of all, we must rule out bleeding in the mouth, throat and other parts. We should treat the cause scientifically, and raise the patient's lower limbs first in order to avoid suffocation caused by blood reflux when vomiting a lot. Generally, conservative medication should be taken first, and the patient's vital signs should be closely monitored. If esophageal varices rupture, vasopressin can be used.

If you spit a small amount of blood, you need to observe whether the bleeding site is in your mouth and measure your blood pressure. If the blood pressure is too high, you can use drugs to reduce blood pressure and gargle with iced salt water or compress with cotton balls to stop bleeding. If brown blood is vomited, accompanied by upper abdominal discomfort or black stool, it should be considered as upper gastrointestinal bleeding. At this time, it is necessary to fast water and send it for inspection immediately. If the patient vomits a lot of blood and shows shock, he should lie flat immediately with his head tilted to one side and be taken to the hospital immediately. If vomiting blood occurs, it is recommended to go to the hospital in time to find out the reason.
