It takes about 1-2 months for a brain hemorrhage clot to be absorbed, and if the clot is small, it may be completely absorbed in about 3 weeks. Once a brain hemorrhage occurs, the clot is mainly in the form of a blood clot in the brain in the early stage, and the clot will gradually autolyze in the brain after about 1-2 weeks, and the blood metabolites will be gradually decomposed after autolysis, which will gradually be absorbed in about 1-2 months. Patients with cerebral hemorrhage need to be hospitalized because the condition of cerebral hemorrhage can easily change, such as the possibility of rebleeding, cerebral edema, intracranial infection, lung infection and other complications, and the consequences are usually relatively serious. Therefore, once a brain hemorrhage occurs, it is necessary to seek immediate medical attention.
