How does the brain block cause it?

The cause of cerebral infarction is related to the following aspects: first, there is no history of hypertension for a long time in the past, long-term hypertension will cause arteriosclerosis, and a long time may cause blockage of cerebral blood vessels to cause cerebral infarction. Second, there is no diabetes in the past, diabetes has certain damage to microvessels and large blood vessels, and diabetes will cause an increase in blood pressure after a certain period of time, so the effects of these two aspects together will accelerate the formation of atherosclerosis causing cerebral infarction. Third, if smoking for a long time will also cause cerebral infarction, smoking is an independent risk factor for cerebral infarction. Fourth, obesity, if the male patient abdominal circumference is larger than the hip circumference, or the female patient body mass index is greater than 25, the risk of cerebral infarction is relatively large, and weight gain is also an independent risk factor for cerebral infarction. Fifth, if the young female patient takes oral contraceptives for a long time, it will also cause increased blood viscosity to cause cerebral infarction.
