Being underweight in young adulthood is associated with an increased risk of intracerebral and subarachoid hemorrhage (stroke types), whereas obesity is associated with increased risk of coronary heart disease and intracerebral infarction.
Maintain a healthy body weight range. While obesity is a known risk for heart disease and ischemic stroke, being underweight in young adulthood is also a risk factor for hemorrhagic stroke. Aim for a balanced weight rather than extreme leanness.

Body mass index (BMI, kg/m2) showed increased risk with CHD and intracerebral infarction, whereas for intracerebral and subarachoid haemorrhage both under- and overweight was associated with increased risk.
Why this rating
Large cohort study with sufficient power to detect type-specific stroke risks.
