When to see a doctor?

If blood spitting occurs, in most cases it is wise to consult a doctor. However, there are also exceptions. If, for example, the gums bleed easily, it is not necessary to see a doctor. However, if no explanation can be found for the spitting up of blood, it is important to have the symptomatology clarified by a doctor.

Spitting blood can have serious causes that, if left untreated, can result in the most serious damage.

In general, spitting up blood should be taken seriously and a doctor should be consulted immediately.

Diagnosis and course

Clarification of the most important vital parameters (pulse, blood prere) and other symptoms or questions about the color of the leaked blood help to find the cause more quickly.

Existing underlying diseases (stomach ulcers, duodenal ulcer) often already provide information about possible causes.

If necessary, gastroscopy or. Colonoscopy, MRI scans, X-ray examinations or immediate surgical intervention necessary. If someone has to spit up blood, a life-threatening situation may exist.

In some cases, X-rays, ultrasound scans or a blood test are needed to determine the cause of the hematemesis.

The course or. The appropriate therapy for hematemesis depends on the underlying disease. For example, the course of illness and therapy of poisoning is different than if the cause is cancer, intestinal problems, nosebleeds with vomiting of swallowed blood or a burst vein in the esophagus.


Since spitting blood can be an indication of a life-threatening condition, this symptom should be treated immediately and a doctor should be consulted.

A further complication of hematemesis is aspiration. Vomit can enter the nasopharynx. There is reflex gagging, which carries the inhaled substances back into the oral cavity. If this is not completely successful, respiratory problems develop and there is a risk of suffocation. In addition, the risk of pneumonia increases.

Treatment and therapy

The treatment for hematemesis depends on the cause found. Often, when spitting blood, emergency surgery is unavoidable. Without hemostasis measures, spitting blood can lead to fatal blood loss. Sometimes the cause can be remedied already during gastroscopy or colonoscopy.

If a burst varicose vein is sclerosed, it is no longer necessary to spit blood. However, if the spitting blood originates from a ruptured gastric ulcer, surgery must be performed immediately. In the case of tuberculosis, which has recently become more frequent again, the possible risk of infection must be taken into account in particular. Similar is the case with syphilis.

The earlier a tumor is detected, the better the chances of cure. Optimally, the diseased tie is completely removed and the blood spitting disappears.

If an eating disorder occurs, vomiting of ingested food is often mechanically induced. This process is extremely stressful for the organism. The more regularly vomiting occurs, the more affected the mucous membranes and organs are. Spitting blood is a warning sign that in most cases does not subside until successful therapy against the eating disorder is initiated. If spitting blood occurs as a symptom of a cold, it subsides as soon as the infarction is cured. Usually, the process takes a few days or weeks to achieve a complete cure.
