Bloody vomiting is a symptom of a disease, and any disease can have several symptoms and they can change during the course of the disease. Therefore, even if at the moment you vomit and everything is fine, this does not mean that your problem is exhausted and the disease has passed. First of all, you need to find the cause of the vomiting of blood. If you feel weakness, dizziness, abdominal pain or repeated vomiting, then you need to go to the hospital (emergency room) immediately. This can manifest a complication of gastric ulcer or 12p intestine - bleeding, perforation of the ulcer.
If you have vomited 1-2 times and your health is not disturbed, then you need to do fibrogastroduodenoscopy - examination of the esophagus, stomach and 12 intestine and consult a gastroenterologist.
In my practice, there was a case when a patient, after a nosebleed, which was quickly stopped, vomited blood the next day. The blood partially entered the stomach when the nasopharynx was manipulated. By gastroscopy, everything turned out to be clean.
An ulcer of the stomach and 12 intestines is the most common cause, but not the only one.
A symptom of damage to the upper third of the gastrointestinal tract. Most likely a stomach ulcer, duodenal ulcer or erosive gastritis, but in the latter case there is not much blood, vomiting is barely tinted with streaks of blood. But it can also be stomach cancer, trauma. The situation is urgent
From opened ulcers and hemorrhoid fever, to stomach cancer and mercury poisoning.
Bloody vomiting is ALWAYS BAD !!! Therefore, go to the doctor immediately. Only death can overcome this symptom.
This symptom requires an immediate emergency call and early diagnosis.
It can be damage to the digestive system, throat, anything from the intestines to the mouth
