What is the effect of pre-diabetes on the risk of stroke?
Research has found that pre-diabetes can increase the risk of stroke. A meta-analysis of multiple studies found that pre-diabetes was associated with a 27% increased risk of ischemic stroke, a 22% increased risk of hemorrhagic stroke, and a 24% increased risk of combined ischemic and hemorrhagic stroke, compared to non-diabetic individuals. Additionally, the Honolulu Heart Program found that glucose intolerance was associated with a 22-year stroke incidence. Other studies have also found that insulin resistance, which is linked to pre-diabetes, is associated with increased risk of stroke.
