What signals does the body send before a stroke? How can I prevent it?

Data studies have shown that most stroke patients will experience varying degrees of dizziness before the attack, such as feeling that the world is spinning, standing unsteadily, and almost falling down after a slight movement. However, this symptom does not last long and usually returns to normal within a few minutes. However, even if it is back to normal, it is important to pay attention to it, which is one of the main manifestations before stroke.

Stroke. Occasional headaches after staying up late are not to be feared, and usually after adequate rest, this headache symptom is effectively relieved. However, if there are frequent headaches that have no cause, it should be taken seriously.

If there are nausea and tinnitus in addition to headache, it may be that the stroke is ringing the alarm bell.

Before the onset of stroke, the tissues in the brain are often in a state of ischemic oxygen, so they are unable to accurately direct and manipulate neural activity, so patients will show unilateral numbness in the limbs. It is important to note that stroke is the opposite of unilateral numbness in the limbs. That is, the left side of the brain has a stroke, and the numbness is the right arm and leg.

On the contrary, it is on the left. At the same time, the numbness will also weaken, such as the inability to hold a cup.

Stroke. In addition to cervical spondylosis and diabetes, if accompanied by symptoms such as headache, dizziness, lightheadedness, tongue swelling, or a history of hypertension, hyperlipidemia, diabetes or cerebral arteriosclerosis, etc., more attention should be paid to the occurrence of stroke.

The most common aura of stroke in middle-aged and elderly people is that the eyes suddenly become black - one eye suddenly blackens, unable to see, and completely return to normal after a few seconds or dozens of seconds.

Stroke. This type of headache occurs suddenly, is concentrated in the temples, lasts from a few seconds to a few minutes, and is often preceded by a feeling of chest tightness or palpitations. Some people present with a whole headache or frontal occipital pain, and the headache is aggravated when coughing, moving, and exertion, and when the headache is severe, there will even be projectile vomiting, blurred vision, and confusion.

The latter is often associated with a sudden increase in blood pressure, which can be relieved after a drop in blood pressure.

Stroke aura refers to the various signs that precede the onset of a stroke and indicates that a stroke may be imminent. There are the following points to pay attention to: 1. Transient amaurosis.

Transient blackening of one eye, due to narrowing or bleeding of the ophthalmic artery, may cause transient amaurosis fugaurosis and is the earliest warning sign of stroke; 2. Severe headache, the nature of the headache is different from the past, the headache is aggravated and persistently aggravated, and it is often a precursor to cerebral hemorrhage and stroke; 3. Obvious dizziness, vertigo accompanied by nausea and vomiting, or symptoms of one limb, such as difficulty in lifting feet or numbness of hands and feet; 4. Symptoms of numbness in the neck and hands, when your neck is turned to one side, the fingers suddenly become numb and weak and recover after 1-2 minutes, which means that the carotid artery has a high degree of stenosis, which requires our attention; In order to fundamentally prevent stroke, the first point is to change the bad habits of the past, such as smoking, drinking, eating too much, intemperate, sedentary, depressed, etc. Second, actively control the corresponding chronic diseases, such as strict control of blood pressure, stabilize blood sugar, and reduce blood lipids. Third, the appropriate re-examination should be carried out as soon as possible to clarify the pattern of disease progression, and if necessary, oral antiplatelet aggregation drugs such as aspirin or clopidogrel**.

Often before the attack, there may be a brief and sudden numbness of one limb, weakness of one limb, sudden poor speech and expression, sudden dizziness, sudden dizziness, sudden feeling that the people are talking about a big tongue, or suddenly walking unsteadily, and a typical symptom, suddenly one eye, we call the monocular haze, suddenly invisible, these are the symptoms of this ischemia that we call transient.

In addition to developing a healthy diet and lifestyle habits, regular brain health check-ups are also an important means of prevention. Through MRI MRA, brain and cerebrovascular diseases can be detected and effectively prevented at an early stage.

Before a stroke, the body will send these four signals: 1. Dizziness of varying degrees (spinning the world, unsteady on standing). 2. Sudden headache, accompanied by nausea, tinnitus and other states.

3. It is especially easy to fall asleep, even if the environment is noisy, you can still fall asleep quickly (before sufficient sleep, sleep quality is also good). 4. Unilateral numbness of the limbs. To prevent stroke, eat a light diet.

Maintain a good attitude If you have one of the above four signs, you should seek medical attention in time.

Body signals before a stroke.

1. Headache When stroke comes, the common manifestation of patients is pain in the head, whether it is bleeding in the head or infarction, both of which will cause obvious pain in the patient's head.

2. Vomiting Many people will have obvious adverse symptoms when they have a stroke, especially vomiting, which may be accompanied by vomiting when they feel dizzy in their heads.

3. Drooling In the process of stroke affecting health, many adverse symptoms will come to the door, and it is generally noted that drooling may be caused by stroke.

To prevent stroke, you should first complete screening for risk factors. If you have underlying diseases, such as diabetes, hypertension, hyperlipidemia, or heart disease, you should adjust your medication under the guidance of a specialist doctor, intervene in these risk factors, and control blood pressure, blood sugar, and blood lipids at an ideal level.

Headaches that have no cause often occur. And on the basis of the head, there are symptoms such as nausea and tinnitus. Unilateral numbness of the limbs is also common. Arm strength will also be weakened. Smoke less and drink less.

Headache: Whether it is a cerebral hemorrhage or cerebral infarction, headache is very common and is an important stroke symptom and signal. Vomiting:

It usually occurs with a headache and is also very common, and is characterized by projectile vomiting. Vomiting of coffee-coloured (soy sauce-like or brownish-black) liquid indicates that the condition is very serious. To prevent stroke, it is necessary to minimise the risk factors for stroke.

Controlling high blood pressure is the focus of stroke prevention. Patients with high blood pressure should take antihypertensive drugs on time according to the doctor's instructions, and it is best to measure blood pressure once a day if possible, especially in the stage of adjusting antihypertensive drugs to keep blood pressure stable. Keep your emotions stable and do less or no things that are easy to cause emotional excitement, such as playing cards, playing mahjong, watching sports broadcasts, etc.; Eat lightly and modestly, quit smoking and drinking, and keep the stool smooth; Moderate activity, such as walking, tai chi, etc.

Before stroke, there will be crooked mouth salivation, aphasia or inability to reach words, difficulty swallowing, weakness or inactivity of one limb, falling of objects, unsteady walking or sudden falling, and limb spasms or throbbing.

Dizziness

Sometimes a dizziness may not be a problem, but if you are habitually dizzy, then you must pay attention to it. If you fall down, you may have a stroke. Life must attach great importance to the matter of dizziness, if you accidentally fall, and there is no one else around, then personal safety can not be ensured.

Body numbness

If a person squats for a long time, then the lower body often feels swollen. This is caused by the crushing of the capillaries and the inability to smooth blood circulation, which is a very routine condition. However, if you find that your body is numb for some reason, you must pay attention to it.

It is very likely that some of the symptoms are caused by the disease, and if it is a stroke, it is generally that one side of the body becomes more and more numb, and it is unsteady to walk, and it must be relieved for a period of time.

If the blood circulation in the body cannot keep up, if the human brain is severely ischemic and the oxygen is insufficient, it is easy to cause a stroke. One of the most striking signs of stroke is slurred words, and it is likely that the period of time for such a thing to continue is very short, but it must be taken seriously. If the corners of the mouth are tilted suddenly, you can also go to the hospital immediately for a check-up to prevent a more obvious stroke.

People who stay up late for a long time can not have a routine repair of the structure of the human body organs, and the blood circulation and basal metabolism in the body will also be harmed, and in the long run, the physical fitness of the body will decline, and the probability of stroke will become much greater. The second is to do more exercise, moderate exercise can not only promote the body's blood circulation, but also maintain the capillaries more physically and mentally healthy, and also have a certain manipulation effect on high blood pressure, improving the body's resistance and immunity.

In the end, it is necessary to drink more water, maintain a healthy diet, and strictly control the three highs, so that the three highs do not directly affect one's blood circulation, otherwise the possibility of stroke will be even greater.

In general, there are already data signals from the body before the stroke, such as numbness, frequent yawning, slurred speech and dizziness. If you want to prevent stroke, you must first cultivate a good schedule of work and rest, don't stay up late, pay attention to fitness and diet, drink plenty of water, and maintain physical and mental health.

Stroke is usually preceded by headache, dizziness, and may be accompanied by visual rotation, nausea, vomiting, and paresthesias in one limb and face. CT or MRI should be done as soon as possible to confirm the diagnosis. It is also necessary to control the patient's blood pressure and lipids in the normal range.

Most patients have no obvious warning for the occurrence of stroke, and only a very small number of patients may experience dizziness, headache, limb weakness, etc. For stroke prevention, the main thing is that it needs to be actively prevented against its associated risk factors. There are many ways to prevent stroke, such as a healthy lifestyle, adjusting diet, quitting smoking and alcohol, controlling risk factors, and secondary prevention of cerebrovascular disease.

You need to choose according to your actual situation.

Weakness of limbs, inability to move, unstable walking, aphasia, inability to speak or difficulty swallowing; Be sure to pay attention to rest, don't eat high-calorie foods, be sure to eat a low-fat and low-sugar diet, should strengthen exercise, and pay attention to rest.

The signs of stroke include dizziness, headache, numbness of the limbs, crooked mouth and slanted eyes, and sudden syncope.

Continuous yawning: When cerebral arteriosclerosis gradually worsens, the lumen becomes narrower and narrower, and cerebral ischemia and hypoxia are aggravated, especially when the respiratory center is hypoxic, it will cause a yawning reflex. In the first 5 to 10 days of ischemic stroke, frequent yawning can reach about 80%, which is an important warning signal.

Stuttering: Symptoms of drooling are poor speech, drooling, signs of stroke, and may occur suddenly.

Darkness: Sudden blackness in front of the eyes, inability to see, recovery within seconds or minutes, accompanied by nausea, vomiting, dizziness and impaired consciousness. Recently, Norwegian physician Coty found carotid atherosclerotic lesions in 11 out of 18 patients with transient amaurosis melodos.

Blurred vision: that is, it manifests as transient visual impairment or visual field defects, which usually recover spontaneously within 1 hour. Coty performed fundus examinations and cerebral blood flow measurements in 10 patients with transient visual impairment and found that three cases had central retinal artery occlusion and seven cases had branch retinal artery occlusion.

Razor landing: When you shave with a knife, your head turns to one side, you suddenly feel weakness in your arm, the razor falls to the ground, and it fully recovers after 1 to 2 minutes. This is due to the distortion of the already hardened carotid artery when the head is turned and the neck is twisted, which aggravates the stenosis and leads to insufficient blood supply to the brain.

Hemimelegia: a transient ischemic attack, which is technically the mildest stroke. According to follow-up observations, more than half of people with transient ischemic attack have an ischemic stroke 3 to 5 years after a transient ischemic attack.

Anyone who has one of the above signs should be examined as soon as possible, and after a clear diagnosis, the system should be carried out to avoid the occurrence of stroke.

There are eight precursors of stroke in middle-aged and elderly people as follows:

1. Dizziness - the precursor of stroke in middle-aged and elderly people, there will be repeated instantaneous dizziness, sudden feeling dizzy, visual rotation, and return to normal after a few seconds, which may be a transient ischemic attack, commonly known as a precursor of stroke, should be diagnosed and treated as soon as possible to prevent stroke.

2. Limb numbness - middle-aged and elderly people have abnormal sensations of limb numbness, in addition to cervical spondylosis, diabetes, such as headache, dizziness, lightheadedness, tongue swelling and other symptoms, or have a history of hypertension, hyperlipidemia, diabetes or cerebral arteriosclerosis and other diseases, should pay more attention to the occurrence of stroke, sudden onset or unilateral limb weakness, unsteady standing, and soon relieve and then attack to be careful.

3. Sudden blackening of the eyes - one eye suddenly blackened, unable to see anything, and completely returned to normal after a few seconds or dozens of seconds, medically called one-time monocular blackness, which is caused by retinal ischemia caused by cerebral ischemia, which is another signal of stroke, and the dizziness and vomiting, visual field narrowing or diplopia are reversed.

4. Unexplained falls in middle-aged and elderly people - due to cerebral vascular sclerosis, cerebral ischemia and motor nerve failure, which can produce ataxia and balance disorders, and easy to fall, which is also a symptom of stroke.

5. Unclear speech - when the cerebral blood supply is insufficient, the nerves of the human motor function fail, one of the common symptoms is that the common symptoms are suddenly ineffective or slurred, or even unable to speak, but the duration is short, the longest is not more than 24 hours, which should be paid attention to, and the unexplained crooked corners of the mouth, slurred speech or tongue protrusion deviation should be noted.

6. Constant yawning - if there is no tiredness, lack of sleep and other reasons, there is continuous yawning, which may be due to cerebral arteriosclerosis and ischemia, which causes chronic ischemia and hypoxia of brain tissue, which is a precursor to stroke patients.

7. Mental changes - such as drowsiness, once the middle-aged and elderly people have unexplained drowsiness and drowsiness, they should pay great attention to it, which is likely to be a precursor to ischemic stroke. Changes in mental status Unusual personality changes, such as becoming reticent, irritable, or transient mental decline, are associated with cerebral ischemia and may be a precursor to stroke.

8. Nosebleeds - Nosebleeds in middle-aged and elderly people may be an alarm that a hypertensive patient is about to have a stroke. After medical observation, trauma and inflammatory factors are ruled out, and patients with high blood pressure may have cerebral hemorrhage after repeated nosebleeds. Many nosebleeds are caused by unstable blood pressure, and if left unprevented, they will increase the risk of stroke.
