Making changes to your lifestyle to make it healthier can reduce your risk of having a stroke. But there are some risk factors that you cannot change.
Men are at a 25% higher risk of having a stroke, and at a younger age, compared to women. Although, because they live longer than men, there are more incidences of stroke in women.
Most people who have strokes are aged over 55, and the risk increases as you get older.
Your ethnic background
Although it's not completely understood why, South Asian, black African and black Caribbean people in the UK are more at risk of stroke than the rest of the population.
None of these factors mean that you will necessarily have a stroke, but it is useful to be aware if you are at increased risk so that you can take steps to live a healthier lifestyle.
