STROKE RISK FACTORS: Risk of stroke and second stroke is influenced by a number of factors. The more stroke risk factors you have, the higher your chances of having a stroke. They fall into three groups:
1. STROKE RISK FACTORS YOU CANNOT CONTROL.
• Age – as you get older, your risk of stroke increases
• Gender – stroke is more common in men
• A family history of stroke
2. MEDICAL STROKE RISK FACTORS.
• Transient Ischaemic Attack (TIA)
• Irregular Pulse (Atrial Fibrillation)
• Fibromuscular Dysplasia (FMD)
3. LIFESTYLE STROKE RISK FACTORS YOU CAN CONTROL
HIGH BLOOD PRESSURE
HIGH BLOOD PRESSURE (hypertension) is the most important known risk factor for stroke. High blood pressure can cause damage to blood vessel walls, which may eventually lead to a stroke.
Lifestyle changes can help lower your blood pressure and your risk of stroke.
HIGH CHOLESTEROL (hyperlipidemia /dyslipidemia) – contributes to blood vessel disease, which often leads to stroke.
SMOKING can increase your risk of stroke or further stroke by increasing blood pressure and reducing oxygen in the blood.
Tobacco smoke contains over 4,000 toxic chemicals which are deposited on the lungs or absorbed into the bloodstream. Some of these chemicals damage blood vessel walls, leading to atherosclerosis (narrowing and hardening of the arteries). This increases the chance of blood clots forming in the arteries to the brain and heart. Smoking also increases the stickiness of the blood. This further increases the risk of blood clots forming. Seek advice on how you can quit smoking as soon as possible by talking to our experts.
OBESITY OR BEING OVERWEIGHT
Being overweight or obese can increase the risk of stroke. Too much body fat can contribute to high blood pressure, high cholesterol and can lead to heart disease and Type 2 diabetes. If you are unable to maintain your weight within recommended levels, ask a doctor or nutritionist for help.
POOR DIET AND LACK OF EXERCISE
Being inactive, overweight or both can increase your risk of high blood pressure, high blood cholesterol, diabetes, heart disease and stroke. People who take part in moderate activity are less likely to have a stroke. Try and build up to at least 30 minutes of moderate physical activity most days of the week.
Talk to your doctor about an exercise program as people with high blood pressure should avoid some types of exercises.
A balanced diet eating fresh foods where possible is recommended. It is also important to maintain a balance between exercise and food intake; this helps to maintain a healthy body weight. Having too much salt in your diet can lead to high blood pressure.
DRINKING TOO MUCH ALCOHOL
ALCOHOL AND STROKE: Drinking large amounts of alcohol (six or more standard drinks per day) increases your risk of stoke
