Stroke is a medical emergency that can cause long-term disability or even death. According to the World Health Organization (WHO), stroke is the second leading cause of death worldwide, with 6.2 million deaths each year.
In addition to the high mortality rate, stroke can significantly impair a person’s quality of life, with survivors often experiencing disabilities such as paralysis, difficulty speaking, and memory loss.
What is a stroke?
A stroke occurs when blood flow to the brain is interrupted, either due to a blood clot (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). Without oxygen and nutrients from blood, brain cells begin to die within minutes.
The symptoms of stroke depend on the area of the brain that is affected, but may include:.
- Sudden weakness or numbness in the face, arm, or leg, usually on one side of the body
- Difficulty speaking or understanding speech
- Sudden confusion or trouble seeing with one or both eyes
- Sudden trouble walking, dizziness, or loss of balance or coordination
- Sudden severe headache with no known cause
Risk factors for stroke
Several factors increase a person’s risk of developing a stroke, including:.
- High blood pressure (hypertension)
- Smoking
- Diabetes
- High cholesterol levels
- Obesity
- Family history of stroke
- Age (risk increases with age, especially after age 55)
- Sedentary lifestyle
- Excessive alcohol consumption
Preventing stroke
The good news is that many of the risk factors for stroke can be controlled or managed through lifestyle changes and medical treatment. Here are some steps you can take to lower your risk of stroke:.
1. Manage high blood pressure
Since high blood pressure is the most significant risk factor for stroke, it’s essential to keep your blood pressure within a healthy range. This can be achieved through healthy eating habits, regular exercise, and medication if necessary.
Talk to your doctor about a target blood pressure goal that’s right for you.
2. Quit smoking
Smoking damages blood vessels and increases the risk of stroke. If you smoke, talk to your doctor about strategies to quit.
3. Control diabetes
Diabetes can damage blood vessels and increase the risk of stroke. Keep your blood sugar levels in check through diet, exercise, and medication as prescribed by your doctor.
4. Lower cholesterol levels
High levels of LDL (“bad”) cholesterol can increase the risk of stroke. You can lower cholesterol levels through a healthy diet, exercise, and medication if needed.
5. Maintain a healthy weight
Obesity increases the risk of several health conditions, including stroke. Aim for a healthy body mass index (BMI) through a balanced diet and regular exercise.
6. Get regular exercise
Regular physical activity can help lower blood pressure, reduce cholesterol levels, and maintain a healthy weight.
Aim for at least 150 minutes of moderate-intensity aerobic activity (such as brisk walking or cycling) per week, or 75 minutes of vigorous-intensity aerobic activity (such as running or high-intensity interval training) per week. Talk to your doctor before starting a new exercise routine.
7. Drink alcohol in moderation
Excessive alcohol consumption can increase blood pressure and the risk of stroke. If you choose to drink, do so in moderation. This means no more than one drink per day for women or two drinks per day for men.
8. Manage stress
Chronic stress can increase blood pressure and contribute to unhealthy habits such as overeating or smoking. Find healthy ways to manage stress, such as meditation, yoga, or talking to a therapist.
Recognizing the signs of stroke
If you or someone you know is experiencing symptoms of stroke, it’s essential to seek medical attention immediately. Delaying treatment can increase the risk of permanent brain damage or death.
Call for emergency services or go to the nearest emergency room if you experience:.
- Sudden weakness or numbness on one side of the body
- Sudden difficulty speaking or understanding speech
- Sudden confusion or trouble seeing
- Sudden severe headache with no known cause
- Sudden trouble walking, dizziness, or loss of balance or coordination
The bottom line
Stroke is a serious medical emergency that can cause long-term disability or death, but it’s also preventable.
By managing risk factors and recognizing the symptoms of stroke, you can help ensure the best possible outcome for yourself or someone you love.
