There are many factors, also known as risk factors , which make a person more susceptible to strokes. Many of these are preventable. Prevention of these can prevent strokes.
Preventable Lifestyle risk factors (that can be prevented or changed)
Smoking.
Lack of physical activity (a sedentary lifestyle).
A strong family history. This means if you have a father or brother who developed heart disease or a stroke before they were 55, or in a mother or sister before they were 65.
Being male.
An early menopause in women.
Age. The older you become, the more likely you are to develop atheroma.
Ethnic group. For example, people who live in the UK with ancestry from India, Pakistan, Bangladesh, or Sri Lanka have an increased risk.
If you have a fixed risk factor, you may want to make an extra effort to tackle any lifestyle risk factors that can be changed and the risk of stroke can be decreased.
