Eating well and following healthy lifestyle habits can lower your chances of developing many diseases, including stroke. Let’s take a closer look at stroke.
What is stroke?
In a stroke, there is not enough blood flowing to the brain.
Most strokes are caused when a blood clot forms inside a blood vessel to the brain. The blood clot blocks the normal flow of blood to the brain. This type of stroke is called an ischemic stroke.
A stroke can also happen when a blood vessel in the brain breaks. This causes bleeding in the brain and also blocks the normal flow of blood to the brain. This type of stroke is called a hemorrhagic stroke.
Risk factors for stroke
These are some important risk factors for stroke:
Age and sex: As you get older, your risk increases. The risk for stroke is higher for men who are over the age of 55, and for women after menopause. Most strokes happen in people over age 65.
Family history: Your risk of stroke is higher if a close family member (parent, sibling or child) had a stroke before age 65.
Ethnicity: First Nations people and people of African or South Asian background are at higher risk for having high blood pressure and diabetes. These conditions put them at a higher risk for stroke too.
Previous stroke or mini-stroke: If you have already had a stroke or a mini-stroke, there is a 20% chance that you will have another stroke within two years.
Lifestyle habits: Your chances of developing stroke also rise if you:
have high blood pressure;
have hardening of the arteries;
have diabetes; or
have a family history of heart problems.
What you can do to lower your risk of stroke

Keep in touch with your doctor
Have regular check-ups with your doctor if you have diabetes, high blood pressure, high blood cholesterol, a family history of stroke or heart disease, or any other type of heart problem. Each of these conditions raises your chances of stroke.
