While female patients at risk of stroke are advised to eat oily fish containing omega-3 fatty acids at least twice a week, omega-3 fatty acid supplements and plant sterols are not recommended as a primary method of stroke prevention, according to Patient. Lifestyle changes may be more helpful instead.
Women at risk of a stroke should follow their doctors' advice regarding management of existing high blood pressure, high cholesterol or diabetes, all of which may contribute to stroke risk. Physicians sometimes recommend daily aspirin or blood thinners for patients at risk of stroke, as WebMD explains. In addition, women at risk of stroke should avoid smoking, limit alcohol consumption to one drink per day and exercise for at least 30 minutes per day.
