Why do I get dizzy so often, please 3Q

There are many causes of dizziness, can you tell me exactly what kind of situation will cause dizziness?

Dizziness, also known as vertigo, is a subjective paresthesia abnormality. It can be divided into two categories: one is rotational vertigo, which is mostly caused by dysfunction of the vestibular nervous system and cerebellum, mainly by the feeling of tipping, feeling that oneself is shaking or the scenery is rotating.

The second is general dizziness, which is mostly caused by some systemic diseases, mainly dizziness and lightheadedness. Classification and Common Diseases Dizziness is a common symptom rather than a separate condition. Therefore, we can classify and describe the diseases that cause dizziness, so that everyone can have a deeper understanding of "dizziness".

1 Rotational vertigo can be divided into two categories: peripheral vertigo and central vertigo. (1) Peripheral vertigo: refers to vertigo caused by the labyrinth of the inner ear or the lesion of the vestibular nerve.

It is commonly seen in Meniere's disease), labyrinthitis (caused by drugs such as streptomycin or gentamicin), and vestibular neuritis. (2) Central vertigo: refers to vertigo caused by lesions of the brainstem, cerebellum, brain and spinal cord.

It is commonly found in vertebrobasilar insufficiency, intracranial tumors, intracranial infections, multiple sclerosis, vertigo epilepsy, and traumatic vertigo. 2 General vertigo (1) Cardiogenic vertigo: common in arrhythmia, cardiac insufficiency, etc.

2) Cormonale vertigo: can be seen in pulmonary insufficiency caused by various causes. (3) Oculogenic vertigo:

It is common in refractive error, fundus arteriosclerosis, hemorrhage and ophthalmoplegia. (4) Hypertensive vertigo: high blood pressure or low blood pressure can cause vertigo.

5) Others: anemia, cervical spondylosis, acute fever, gastroenteritis, endocrine disorders and neurosis, etc.

Dizziness is a phenomenon caused by the dilatation of blood vessels and the increase in blood flow, resulting in a decrease in blood flow to the brain. This phenomenon may occur due to exposure to the scorching sun for too long, taking a hot bath for too long, or being nervous or angry. In addition to the above reasons, vitamin deficiencies, hormonal abnormalities, menopause or autonomic disorders can also contribute to dizziness.

Depending on the cause, dizziness can be divided into the following types. Only the face is hot, and the hands and feet are cold – most often seen in women around the age of 50. Most of them are due to menopausal hormone imbalance.

The endocrine glands and hormones in the human body can cope with the body's activity and external temperature, and have the function of regulating the smooth operation of the body. During menopause, the secretion of sex hormones decreases or even stops, and many changes occur in the body, such as stiff shoulders and headaches, as well as symptoms such as dizziness and cold hands and feet. Sudden onset of dizziness:

It is a disorder of the autonomic nervous system. It can also be referred to as a type of vasomotor nerve. It is usually seen in women, and is accompanied by symptoms such as headache, dizziness, fatigue, and cold in the lower body.

Dizziness in a state of frequent general fever: If accompanied by intense palpitations and body tremors, it is a phenomenon of hyperthyroidism, which is due to excessive thyroxine secretion that makes the metabolism vigorous, and the whole body feels hot and dizzy at any time. In addition, it may also be high blood pressure, if the blood pressure is persistent, the dizziness persists, and the headache symptoms occur at the same time, there is a risk of stroke, so be careful.

If dizziness is accompanied by any other symptoms, it is important to consult a doctor. If the dizziness is not caused by the disease, it can be improved without seeking medical attention; It is also important to exercise moderately and eat more foods containing vitamins, protein and iron.

The question you are asking is a symptom in medicine, there are so many conditions that can cause dizziness, and the descriptions of "dizziness" are well organized in internal medicine books or other books on symptomatology, and can be seen in hundreds of diseases, even if you put those books in front of you, you can't tell which one of your conditions is, but it will make you even more dizzy. I can't answer you specifically, but I can give you an account of the onset of the disease. First of all, it is the same dizziness, the old age is different, the men and women are different, the nature of work and lifestyle are different.

Most of the dizziness of young people is related to lifestyle, such as staying up late for a long time, playing computer games for a long time, taking drugs, taking drugs indiscriminately (sex drugs, tonics, ** drugs, etc.), excessive drinking, excessive sex, etc. And high stress at work is often the cause of dizziness in young people, and women often get dizzy during menstruation. However, dizziness symptoms occur in older people (over 40 years old, especially with "three highs"), thinking can not be the same, with the increase of age, the incidence of cardiovascular and cerebrovascular diseases increases.

If this is the case, it is necessary for the person to go to the hospital for examination. In the past, dizziness usually thought about whether there was a problem with blood pressure and whether hypoglycemia occurred (in the past, it belonged to the era of low material life and lack of spiritual life), and now dizziness patients are more and more common, more and more young, and it cannot be ignored that it is related to social development factors. In addition, unsafe eating and drinking can also cause unexplained dizziness.

If you are a young person, don't consider cardiovascular and cerebrovascular diseases. Your condition is most likely caused by a lack of rest and poor sleep quality. It is recommended that you increase the quality of sleep and do not stay up late.

Remember to adopt it.
