It is generally believed that people whose weight exceeds 20 % of the standard weight are obese. The relationship between obesity and stroke is not exact. However, the risk of hypertension, diabetes and coronary heart disease is significantly increased in obese people, so obesity may indirectly affect the occurrence of stroke. It is generally believed that only obese people have high blood lipids. In fact, hyperlipidemia is mainly caused by abnormal lipid metabolism. Non-obese people may also have high blood lipids, but obese people are more likely to have hyperlipidemia. The relationship between blood lipids and stroke is still not very sure. But now recognized hyperlipidemia can promote atherosclerosis,cerebrovascular disease is one of the risk factors. Neutral fat, also known as low-density lipoprotein, is an aggressive lipid that can promote atherosclerosis, while high-density lipoprotein can prevent atherosclerosis. Increased low-density lipoprotein and decreased high-density lipoprotein increase the risk of stroke. Therefore, it is necessary to control body weight and blood lipids in those who are significantly overweight.
