It is difficult to specify how long it is normal to be in a coma after a cerebral hemorrhage, because cerebral hemorrhage is related to the amount of bleeding, the individual’s physical condition and other aspects, so it is necessary to analyze the specific situation. If a patient has a brain hemorrhage that causes a coma, and if the patient is in good physical condition and has no other underlying diseases, the coma will often last less than a week. After the patient’s coma caused by cerebral hemorrhage, dehydration and cranial pressure lowering treatment should be carried out under the guidance of the doctor, and usually the patient can gradually return to normal in about one week after the treatment. However, there are some patients who are not treated in time because of the elevated intracranial pressure, or they have some underlying diseases, the coma time will be prolonged accordingly, and they may be in coma for about one month or even longer. Patients with cerebral hemorrhage coma need timely treatment to avoid the serious consequences of untimely treatment.
