What is the relationship between obesity and stroke risk?
Studies have shown that there is a positive correlation between obesity and stroke risk, with a 40% increased stroke mortality with each 5-kg/ increase in Body Mass Index (BMI). When diabetes mellitus, hypertension, dyslipidemia, and other confounders were taken into account, there was no significant increase in the incidence of hemorrhagic stroke. However, in the BMI range of 15 to 24 kg/ , there was no relationship between BMI and mortality.
