Black stool with blood what happened

Black stool with blood, consider the possibility of upper gastrointestinal bleeding. This is clinically more common in stomach and duodenal ulcer. The causes of the disease are mostly related to the patient's excessive acid secretion and the weakening of gastrointestinal mucosal barrier function and Helicobacter pylori infection. Ulcer invasion of mucosal blood vessels can cause symptoms of upper gastrointestinal bleeding such as melena and vomiting blood. The stool is tarry and typical of upper gastrointestinal bleeding. Gastroscopy can be carried out in hospital. If upper gastrointestinal bleeding is diagnosed, acid inhibitors, gastrointestinal mucosal protective agents and hemostatic drugs can be applied under the guidance of doctors for symptomatic treatment. Surgery may be considered if necessary.
