Our brain also needs blood to supply nutrition. If there is something wrong with the blood vessels supplying the brain, it may lead to a stroke. Blood vessels are the same as the water pipes we see every day. If it is used for a long time, if it is not maintained, problems will inevitably occur. If there is a problem, they will block or leak. The water pipe is broken and can be replaced at any time. A broken blood vessel in the brain is no joke. Because the brain exists in the cranial cavity, when blood oozes out, it will oppress the brain and lead to functional failure of the body; When blood vessels in the brain are blocked and blood cannot flow, the part of the brain that depends on blood vessels will be hypoxic and necrotic.
There will be some symptoms before a stroke. If the following symptoms appear, you should seek medical advice promptly.
1, dizziness and headache
When the blood vessels in the brain are abnormal, dizziness and headache may occur, such as rotating and shaking foreign objects, or persistent headache. Everyone's condition is different, and the duration is different. Some people will be accompanied by nausea, vomiting, tinnitus and other phenomena.
2. Language barriers
When a language cannot be fully expressed, or the expression is not clear enough, it will return to normal after more than ten minutes or hours, which may be a precursor to cerebral ischemia.
3, limb numbness
If one side of the body is suddenly numb, and other possible reasons for numbness are ruled out, it is necessary to consider whether it is a cerebrovascular problem. Can self-test, that is, arms are horizontally straight forward. If one side can't be straightened, check it in time.
4, the line of sight is blurred, and there is a ghost.
If you suddenly find that your eyes are dark, you can't see clearly, or even have a double image, you should consider whether it is caused by cerebrovascular disease.
Some patients will also have symptoms such as sudden forgetfulness, choking cough when drinking water, and mouth and eyes askew. Some patients have never had any symptoms. So prevention is the most important thing. Diet should be low in salt, sugar and fat, eat more fresh fruits and vegetables, and pay attention to drinking water at ordinary times, which can effectively dilute blood. Stay away from alcohol and tobacco, stay up late less, these are the pathogenic factors that destroy the inner wall of blood vessels. In addition, proper physical exercise is needed. If you have hypertension, hyperlipidemia and diabetes, you must control the basic diseases to avoid cardiovascular and cerebrovascular diseases.
