What Is a Stroke?
If you get a stroke, that means the brain's blood flow has been cut off. It's an emergency because the portion of your brain that's affected begins to fail quickly without oxygen and nutrients from the blood. As a result, you or anyone with you should contact 999 immediately. Symptoms include:
- Sudden numbness or weakness on one side of the body
- Inability to speak
- One eye has double or blurred vision
- Sudden dizziness or falling
Strokes, sometimes known as “brain attacks," occur in one of two ways:
- A clot prohibits blood from flowing to the brain. This is referred to as “ischaemic" strokes.
- A blood vessel in the brain bursts or leaks. This is referred to as a “haemorrhagic" stroke.
Brain cells will only survive for a few minutes without oxygen in either type of stroke.
sed by Bleeding
This occurs as a result of brain bleeding. Strokes that are “haemorrhagic" are less common than ischaemic strokes, but they may be more severe and have a higher risk of mortality.
It usually occurs when an aneurysm explodes, which is a thinned or weakened area on an artery that has ballooned due to pressure. Other occasions, fatty plaque tends to cause the artery wall to become brittle over time, causing it to break open.
How to Lower Your Risk
Strokes could strike at any age, even infants in the womb. But so, after middle age, the chances of having a stroke increase rapidly.
To reduce your chances of getting a stroke, do the following:
Keep your blood pressure healthy. This is the single most crucial factor you can do to reduce the chances of having a stroke if you have high blood pressure (consistently above 130/80).
Avoid tobacco. Cigarette smoking and chewing tobacco, as well as secondhand smoke, produce physical modifications in the body. They may cause fatty accumulation in your arteries by thickening your blood and increasing the likelihood to clot.
Control your cholesterol levels. High levels of LDL, or “bad" cholesterol, increase the odds of plaque forming in the arteries, raising your chance of a clot leading to a heart attack or stroke.
Manage diabetes, if you have it. If it’s not under control, it can lead to a stroke by damaging your blood vessels.
Check your weight and waist. If these numbers fall within a safe range, the doctor will inform you. If you have a waist circumference that measures more than 40 inches for men and more than 35 inches in circumference for women, you might be at a greater risk.
