High blood pressure can lead to cerebral hemorrhage, cerebral hemorrhage is one of the most important complications of high blood pressure, about 40% of patients with cerebral hemorrhage have a history of high blood pressure. Long-term high blood pressure makes the tiny cerebral arteries harden and the elasticity of the blood vessel walls weaken, so when the blood pressure rises suddenly, the blood vessels are prone to rupture and bleed. In addition, high blood pressure can also cause ischemia and deformation of cerebral blood vessels, forming tiny aneurysms, which are also prone to rupture and cerebral hemorrhage when blood pressure fluctuates violently. Therefore, hypertensive patients should achieve a healthy lifestyle, low-salt and low-fat diet, appropriate exercise, weight reduction, quit smoking and alcohol, regular work and rest, maintain a good state of mind, avoid emotional excitement, as well as regular monitoring of blood pressure, so as to control the blood pressure in the ideal range and prevent the occurrence of complications.
