A stroke is like a heart attack of the brain. During a stroke, the brain does not receive adequate blood supply and oxygen to function correctly. The brain cells die without sufficient oxygen and nutrients, causing severe brain damage. Depending on which part of the brain is affected, loss of speech, hearing, taste, vision or movements crops up as a consequence due to various causes of stroke.
A stroke might occur due to a variety of reasons, but here are the three main causes of stroke:
- Blood clots:
Blood clots are formed in the arteries of the brain or are formed in the other blood vessels. These then break off and travel where they might enter the narrow arteries of the brain. Here, they restrict blood flow to the part of the brain that is supplied blood by that artery leading to a stroke. This leads to loss of function of the body part controlled by the brain region.
- High blood pressure:
High blood pressure or hypertension may cause the blood vessels to rupture or tear in the brain. The spilt blood damages the adjacent brain cells leading to cell death and loss of function of corresponding body parts.
- Other factors:
Other factors such as a traumatic brain or neck injury, certain medications and weakness in the internal walls of our arteries and veins also increase the cause of stroke.
The best way to avoid stroke is to control the formation of unhealthy cholesterol and exercise regularly to keep ourselves fit and healthy. All means of maintaining blood pressure must be undertaken.
- Diet is one the most critical factors that help to keep us healthy and fit. Eat plenty of fresh fruits and vegetables every single day and avoid fried and processed food as much as possible. Salt restriction is essential.
- Exercise regularly to keep your body fit and healthy. Exercise not only helps in the long run to lower blood pressure levels but also reduces stress, which in turn reduces the risks of having a stroke.
- Smoking dramatically increases the risks of blood clot formation. Moreover, smoking also increases the plaque buildup in our arteries, which is the underlying cause of a stroke. Give up smoking for good.
- Alcohol intake increases blood pressure that leads to stroke. Avoid alcohol intake or drink in moderation no more than twice a week.
Stroke is a preventable condition that can be avoided by following these lifestyle modifications. Lets spread awareness about the causes of stroke and promote healthy living.
