Can melena caused by gastrointestinal bleeding heal on its own?

Black stool due to gastrointestinal bleeding generally does not resolve spontaneously. Once gastrointestinal bleeding occurs, it is important to promptly identify the exact site of bleeding through examinations such as gastroscopy or colonoscopy. If necessary, hemostatic medications should be taken as directed by a physician to alleviate the condition. Additionally, when mucosal damage is present, timely treatment with acid-suppressive and mucosal-protective agents is required.
