Stroke (Part 2)
Risk factors
Many factors can increase your stroke risk. Potentially treatable stroke risk factors include:
Lifestyle risk factors
Being overweight or obese
Physical inactivity
Heavy or binge drinking
Use of illegal drugs such as co***ne and methamphetamine
Medical risk factors
High blood pressure
Cigarette smoking or secondhand smoke exposure
High cholesterol
Diabetes
Obstructive sleep apnea
Cardiovascular disease, including heart failure, heart defects, heart infection or abnormal heart rhythm, such as atrial fibrillation
Personal or family history of stroke, heart attack or transient ischemic attack
Other factors associated with a higher risk of stroke include:
Age — People age 55 or older have a higher risk of stroke than do younger people.
Race — African Americans have a higher risk of stroke than do people of other races.
S*x — Men have a higher risk of stroke than women. Women are usually older when they have strokes, and they're more likely to die of strokes than are men.
Hormones — Use of birth control pills or hormone therapies that include estrogen increases risk.
Complications
A stroke can sometimes cause temporary or permanent disabilities, depending on how long the brain lacks blood flow and which part was affected. Complications may include:
Paralysis or loss of muscle movement. You may become paralyzed on one side of your body, or lose control of certain muscles, such as those on one side of your face or one arm.
Difficulty talking or swallowing. A stroke might affect control of the muscles in your mouth and throat, making it difficult for you to talk clearly, swallow or eat. You also may have difficulty with language, including speaking or understanding speech, reading, or writing.
Memory loss or thinking difficulties. Many people who have had strokes experience some memory loss. Others may have difficulty thinking, reasoning, making judgments and understanding concepts.
Emotional problems. People who have had strokes may have more difficulty controlling their emotions, or they may develop depression.
Pain. Pain, numbness or other unusual sensations may occur in the parts of the body affected by stroke. For example, if a stroke causes you to lose feeling in your left arm, you may develop an uncomfortable tingling sensation in that arm.
Changes in behavior and self-care ability. People who have had strokes may become more withdrawn. They may need help with grooming and daily chores.
Prevention
Knowing your stroke risk factors, following your doctor's recommendations and adopting a healthy lifestyle are the best steps you can take to prevent a stroke. If you've had a stroke or a transient ischemic attack (TIA), these measures might help prevent another stroke. The follow-up care you receive in the hospital and afterward also may play a role.
Many stroke prevention strategies are the same as strategies to prevent heart disease. In general, healthy lifestyle recommendations include:
Controlling high blood pressure (hypertension). This is one of the most important things you can do to reduce your stroke risk. If you've had a stroke, lowering your blood pressure can help prevent a subsequent TIA or stroke. Healthy lifestyle changes and medications are often used to treat high blood pressure.
Lowering the amount of cholesterol and saturated fat in your diet. Eating less cholesterol and fat, especially saturated fat and trans fats, may reduce the buildup in your arteries. If you can't control your cholesterol through dietary changes alone, your doctor may prescribe a cholesterol-lowering medication.
Quitting to***co use. Smoking raises the risk of stroke for smokers and nonsmokers exposed to secondhand smoke. Quitting to***co use reduces your risk of stroke.
Managing diabetes. Diet, exercise and losing weight can help you keep your blood sugar in a healthy range. If lifestyle factors don't seem to be enough to control your diabetes, your doctor may prescribe diabetes medication.
Maintaining a healthy weight. Being overweight contributes to other stroke risk factors, such as high blood pressure, cardiovascular disease and diabetes.
Eating a diet rich in fruits and vegetables. A diet containing five or more daily servings of fruits or vegetables may reduce your risk of stroke. The Mediterranean diet, which emphasizes olive oil, fruit, nuts, vegetables and whole grains, may be helpful.
Exercising regularly. Aerobic exercise reduces your risk of stroke in many ways. Exercise can lower your blood pressure, increase your levels of good cholesterol, and improve the overall health of your blood vessels and heart. It also helps you lose weight, control diabetes and reduce stress. Gradually work up to at least 30 minutes of moderate physical activity — such as walking, jogging, swimming or bicycling — on most, if not all, days of the week.
Drinking alcohol in moderation, if at all. Heavy alcohol consumption increases your risk of high blood pressure, ischemic strokes and hemorrhagic strokes. Alcohol may also interact with other drugs you're taking. However, drinking small to moderate amounts of alcohol, such as one drink a day, may help prevent ischemic stroke and decrease your blood's clotting tendency. Talk to your doctor about what's appropriate for you.
Avoiding illegal drugs. Certain street drugs, such as co***ne and methamphetamine, are established risk factors for a TIA or a stroke.
