Arachnoid hemorrhage is generally referred to as subarachnoid hemorrhage. There is no authoritative information on how long it takes for a mild subarachnoid hemorrhage to be normal; usually patients bleed for about a week to three weeks, but it is impossible to generalize because of the variability that exists in individuals.
Subarachnoid hemorrhage is caused by blood flowing into the subarachnoid space after a rupture of a blood vessel in the skull. Patients may experience a sudden, severe headache that is distending or popping and is unbearable, and is accompanied by vomiting, nausea, and headache.
If the patient has a mild subarachnoid hemorrhage, the normal bleeding time is usually about one week, but if some patients have relatively large amounts of bleeding, it may take about three weeks. It is not possible to make a generalization, as it depends on the patient’s condition.
Once a patient has a subarachnoid hemorrhage, he or she should go to a regular hospital and take relevant treatment measures under the guidance of a physician. At the same time, avoid spicy, fried, deep-fried, alcohol and other foods, light, easy to digest, nutritious food.
