Studies have shown that obesity is not only a risk factor for coronary heart disease, but there is a positive association between obesity and stroke, and is an independent risk factor for stroke.
A prospective study on stroke showed that at a body mass index (BMI) of 25-50 kg/m2, the incidence of stroke increased by 40% for every 5 kg/m2 increase in BMI.
When BMI is between 15 and 24 kg/m2, BMI is not associated with stroke occurrence, therefore, BMI is recommended to be controlled within 24, but it is not necessary that BMI > 25 has insufficient blood supply to the heart and brain, only that the proportion of the disease is high, and daily attention needs to be paid to more exercise, weight control and maintaining a healthy diet, etc.
