When a portion of the brain loses its blood supply and stops functioning, a stroke occurs. Brain cells begin to die within minutes if the blood’s oxygen supply is cut off. As a result, the portion of the body that the injured brain controls stops functioning.
Types of Stroke
There are two main types of Stroke
It occurs when fatty deposits in arteries fragment and travel to the brain or when poor blood flow from an irregular heartbeat causes a blood clot, a blood vessel that supplies blood to the brain becomes blocked.
Although less frequent than an ischemic stroke, it can be more serious. This occurs when a blood vessel in the brain swells up and bursts, or one that is weak leaks.
Some individuals experience transient ischemic attacks (TIA). There is a brief blockage to blame for this “mini stroke.”
Causes of Stroke
High blood pressure
It is the primary contributor to strokes.
Overweight may increase your risk of having a stroke. By exercising daily, you can reduce your chances of getting a stroke.
Atrial fibrillation, or an irregular heartbeat, which accounts for a quarter of all strokes among the very elderly, as well as faulty heart valves are all part of this condition.
Blood vessel damage from diabetes increases your risk of having a stroke.
Your risk of having a stroke increases if you smoke or chew it. Nicotine increases blood pressure. Your main neck artery develops an accumulation of fatty tissue as a result of smoking. Your blood becomes thicker and is more likely to clot as a result. Even passive smoking has an impact on you.
