Patients with advanced gastric cancer who experience black water vomiting symptoms are mainly caused by tumor bleeding, as the blood is destroyed by stomach acid in the stomach, so the vomited liquid will appear black. The appearance of this symptom often indicates that the condition is more serious and if not treated in a timely manner, serious complications arise that can easily cause life-threatening conditions.
The clinical symptom of vomiting black water also does not specifically determine survival. If a patient with advanced gastric cancer develops this symptom, survival may be only a year or a few months, but if treatment is aggressive, it can effectively extend the patient’s survival.
