There are many kinds of diseases that cause vertigo, about hundreds of diseases can cause vertigo, and the causes of different diseases are different. People feel dizzy. In the final analysis, balance is destroyed. Maintaining balance requires human's vestibular system, vision system and deep sense system to participate. Any system can cause dizziness. Therefore, according to the location of the lesion, it is divided into vestibular vertigo and non vestibular vertigo. The former accounts for the majority of vertigo, and it can be divided into two categories: vestibular peripheral vertigo and vestibular central vertigo. Central vertigo is caused by brain tissue and brain nerve diseases, such as acoustic neuroma and cerebrovascular disease, which accounts for about 30% of the total number of vertigo patients. Peripheral vertigo accounts for about 70%. Most peripheral vertigo is related to facial features. Most of the cases are accompanied by cochlear symptoms such as hearing changes, tinnitus, and other autonomic nervous symptoms such as nausea, vomiting and sweating. Some diseases can be recurrent vertigo and can be relieved by themselves.
The common causes of vertigo are:
1.: because of work or neurosis psychogenic tension, sleep, emotional factors, some people will be dizzy It is without rhyme or reason.. This kind of halo will not be very bad, and usually it will recover for a while, but sometimes it will last for more than half a day.
2., benign paroxysmal positional vertigo: otoliths in the vestibule and otolith are shedding into sensitive areas for some reasons, resulting in bad stimulation and vertigo, which is called benign paroxysmal positional vertigo.
3., systemic diseases: hypertension, diabetes and asthma are also often vertigo. Sometimes, patients who take antihypertensive drugs or diabetes medications will cause dizziness due to overdose, resulting in low blood pressure or blood sugar. Some heart problems such as severe arrhythmias, myocardial ischemia, and heart failure can also lead to vertigo.
4. cerebrovascular disease: cerebral infarction or cerebral ischemia can cause insufficient blood supply to the vestibular organ and vestibular center, and intracerebral hemorrhage can cause vertigo due to compression of the vestibular center of the brainstem and cerebellum.
5. Meniere's disease: the patient often dizziness for several hours to a day or more, and accompanied by tinnitus and hearing impairment, nystagmus. The pathological changes in the inner ear are "endolymphatic system hydrops", but the real mechanism is still unclear. Many doctors all belong to the virtue of vertigo, in fact it is the diagnosis of hearing examination and the long history of the need to observe the diagnosis.
6. vestibular neuritis: often soon after the cold, suddenly very severe vertigo, vomiting. The patient's hearing is normal, his mind is clear, but he is very dizzy. He can't move in bed, accompanied by severe eye shaking. This vertigo usually lasts for about ten days and then returns to normal.
7. chronic otitis media: complications of chronic otitis media, especially with cholesteatoma patients, sometimes causing damage to the lost canal, Chan tube and vertigo, so chronic otitis media should be treated actively, avoid complications.

Dizziness is just a symptom. Many diseases on the clinic can cause dizziness. Dizziness is a common functional disorder of the brain, and it is also a common clinical symptom. Dizziness, headache, top-heavy, brain shaking, vertigo and feeling. Dizziness can be caused by many reasons, most common in febrile disease, hypertension, cerebral arteriosclerosis, craniocerebral trauma syndrome, neurosis and so on. In addition, it is also seen in anemia, arrhythmia, heart failure, hypotension, drug poisoning, uremia, asthma and so on. Depression is also often dizzy in the early stages of depression. Dizziness can be found alone, but often complicated with headache. When dizziness is accompanied by disturbance of balance or spatial orientation, the patient feels the peripheral environment or itself in rotation, movement, or swaying, known as dizziness.
Dizziness can be caused by a variety of diseases, and the most common are the following:
1. Headache caused by head lesions. It is divided into headache caused by intracranial diseases and headache caused by extracranial diseases.
2. The symptoms of brain injury: the head had been injured in the past few days. A headache lasts more than a day, or after a few seconds of injury, it loses consciousness, a burst of headaches, memory loss, and vomiting.
3, anemia elderly, such as dizziness, fatigue, pale appearance, should go to the hospital to check to see if anemia. If the elderly do not pay attention to nutrition and health care, it is very easy to suffer from anemia. In addition, the elderly patients with dyspepsia, peptic ulcers, gastrointestinal bleeding and chronic inflammatory diseases can secondary anemia.
4, hypertension in patients with dizziness, headache, palpitation, often accompanied by irritability, tinnitus, insomnia and other discomfort.
5, heart disease early coronary heart disease, some people may feel headache, dizziness, extremities weakness, mental difficulty concentration and so on. The main reason is the atheromatous atherosclerosis of the coronary artery, which causes the insufficiency of blood supply and causes dizziness.
6, high blood viscosity, high blood fat and thrombocythemia can all cause high blood viscosity and slow blood flow, which can cause blood supply to the brain and cause fatigue, dizziness, fatigue and other symptoms. The cause of hyperlipidemia is many, the most important is the normal diet structure.
7, cerebral arteriosclerosis patients consciously dizziness, and often insomnia, tinnitus, emotional instability, forgetfulness, limbs numbness. Cerebral arteriosclerosis reduces the diameter of the blood vessels and decreases the blood flow in the brain, resulting in brain blood supply, insufficient oxygen supply and dizziness.
8, cervical spondylosis often appears to have a tight neck, limited flexibility, occasional pain, numbness and cold, and a heavy feeling. Cervical vertebra hyperplasia squeezing cervical vertebral artery, causing brain insufficiency, is the main cause of dizziness caused by the disease.
A variety of diseases can cause dizziness, so it is necessary to make clear the specific causes of disease, targeted treatment.

General dizziness is divided into general dizziness and vertigo. The former is characterized by dizziness, head sinking, and a sense of unconsciousness. The latter is characterized by visual rotation, sway or swaying sensation, accompanied by sweating, nausea, vomiting, pale complexion, unsteady walking or standing, and blood pressure drop.
Dizziness for many reasons, but more common in cerebrovascular disease, Meniere's disease, symptom, syndrome, cervical vertigo otolith disease and medical system diseases (such as hypertension, diabetes, blood diseases).
Dizziness is mainly divided into two categories, general dizziness, caused by some systemic diseases, to dizziness feeling, feel top-heavy; rotary ertigo, by the vestibular system and cerebellum dysfunction caused by the feeling of to dump; often cause dizziness and there are several reasons:
1, the cause of rotation often dizziness:
(1) Central dizziness: refers to recurrent dizziness caused by lesions of brain stem, cerebellum, brain and spinal cord. It is commonly seen in vertebrobasilar insufficiency, intracranial tumor, intracranial infection, multiple sclerosis, vertigo, epilepsy and traumatic vertigo.
(2) around the dizziness refers to recurrent dizziness caused labyrinth or vestibular lesions, common in Meniere's disease "has been translated, Meniere's disease), dizziness (labyrinthitis drugs caused by streptomycin or gentamicin after administration) and vestibular neuritis.
2, the common causes of dizziness are:
(2) blood pressure dizziness: high blood pressure or hypotension can cause dizziness.
(3) cardiogenic dizziness: common in arrhythmia, heart function inadequacy will cause frequent dizziness.
(4) eye source dizziness: common in refractive error, fundus arteriosclerosis, bleeding and ophthalmoplegia, and other ophthalmological diseases will cause frequent dizziness.
(5) frequent dizziness caused by other causes:
A, high blood viscosity, hyperlipidemia and thrombocytosis can make blood viscosity high, blood flow slow, cause blood supply in the brain, often cause dizziness symptoms.
B, cervical vertebra hyperplasia squeezing cervical vertebral artery, causing brain insufficiency, is the main cause of dizziness caused by the disease.
C, coronary artery atheromatous atherosclerosis in the early stage of coronary heart disease, resulting in frequent dizziness caused by insufficient blood supply.
D, anemia can also cause cerebral blood supply deficiency, if the anemia is serious, there will be frequent dizziness.

Dizziness, also known as vertigo, is a subjective sensation. It can be divided into two categories: one is vertigo vertigo, mostly caused by dysfunction of vestibular nervous system and cerebellum, and the sensation of dumping is the main cause, and it feels itself shaking or scene rotation. The general dizzy, caused by some systemic diseases, to dizziness feeling, feel top-heavy.
1. rotatory vertigo can be divided into two types: peripheral vertigo and central vertigo according to its cause.
(1) peripheral vertigo: vertigo caused by the lesion of the inner ear or the vestibule nerve. Common in Meniere's disease "has been translated, Meniere's disease), vertigo, labyrinthitis drugs (caused by streptomycin or gentamicin after administration) and vestibular neuritis.
(2) central vertigo: the vertigo caused by the brain stem, the cerebellum, the brain and the spinal cord. It is common in the insufficiency of vertebrobasilar artery, intracranial tumor, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo.
2. general vertigo
(1) cardiogenic vertigo is common in cardiac arrhythmias and cardiac dysfunction.
(2) pulmonary vertigo: a variety of causes of pulmonary insufficiency.
(3) ocular vertigo is common in ametropia, fundus arteriosclerosis, bleeding and ophthalmoplegia.
(4) blood pressure vertigo: high blood pressure or hypotension can cause vertigo.
(5) other: cervical vertebra disease, anemia, fever, acute gastroenteritis, endocrine disorders and neurosis can cause dizziness
1. elderly anemia elderly, such as dizziness, fatigue, pale appearance, should go to the hospital to check to see if anemia. If the elderly do not pay attention to nutrition and health care, it is very easy to suffer from anemia. In addition, the elderly patients with dyspepsia, peptic ulcers, gastrointestinal bleeding and chronic inflammatory diseases can secondary anemia. 2., blood viscosity, hyperlipidemia, thrombocythemia, etc. can make blood viscosity high, slow blood flow, resulting in blood supply to the brain, easy fatigue, dizziness, fatigue and other symptoms. The cause of hyperlipidemia is many, the most important is the normal diet structure. 3. patients with cerebral arteriosclerosis are dizzy and dizzy, and often insomnia, tinnitus, emotional instability, forgetfulness and numbness in the limbs. Cerebral arteriosclerosis reduces the diameter of the blood vessels and decreases the blood flow in the brain, resulting in brain blood supply, insufficient oxygen supply and dizziness. The 4. cervical spondylosis often appears to have a tight neck, limited flexibility, occasional pain, numbness of the fingers, a cool hair, and a heavy feeling. Cervical vertebra hyperplasia squeezing cervical vertebral artery, causing brain insufficiency, is the main cause of dizziness caused by the disease. 5. hypertension patients in addition to dizziness, headache, palpitation, often accompanied by irritability, tinnitus, insomnia and other discomfort. 6. heart disease in the early stage of coronary heart disease, some people may feel headache, dizziness, limb weakness, mental difficulty concentration and so on. The main reason is the atheromatous atherosclerosis of the coronary artery, which causes the insufficiency of blood supply and causes dizziness. 1. the best solution to dizziness is to prevent it. The elderly should regularly check blood pressure, heart sounds, heart rhythm, blood routine, blood lipids, blood viscosity, electroencephalogram, cerebral blood flow and neck X-ray, and prevent them.
