To understand how to prevent cerebral hemorrhage, we need to clarify what causes it. Generally, the most common cause of cerebral hemorrhage is hypertension. Long-term hypertension can lead to hyaline degeneration of the walls of small arteries and occlusion necrosis. Over time, small arteries rupture, leading to cerebral hemorrhage. Other blood system diseases, such as leukemia, deficiency of clotting factors, some tumors, and cerebral vascular malformations, can also cause cerebral hemorrhage. Therefore, the most important preventive measure is to actively control blood pressure. Regularly, one must maintain a low-salt, low-fat diet, engage in appropriate physical activities, enhance physical fitness, avoid smoking, and abstain from alcohol to effectively prevent hypertension and avoid hypertension-induced cerebral hemorrhage. For cerebral hemorrhage caused by other reasons, regular health check-ups should be done, including complete blood counts and coagulation tests, to rule out blood diseases causing cerebral hemorrhage.
