Dizziness

Introduction

Introduction Dizziness is a common brain dysfunction and one of the most common clinical symptoms. It is a feeling of dizziness, head swelling, top-heavy, shaking in the brain, and squinting. Dizziness can be caused by a variety of causes, most commonly in febrile diseases, hypertension, cerebral arteriosclerosis, craniocerebral trauma syndrome, neurosis, and the like. In addition, it is also found in anemia, arrhythmia, heart failure, hypotension, drug poisoning, uremia, asthma and the like. Dizziness is often seen in the early stages of depression. Dizziness can occur alone, but often with headaches. When dizziness is accompanied by a balance disorder or a spatial dysfunction disorder, the patient feels that the peripheral environment or itself is rotating, moving or shaking, called dizziness.

Cause

Cause

Dizziness, many people think it is a small problem, dizziness when hungry, dizziness before and after menstruation, long time standing up will be dizzy. Under normal circumstances, occasional dizziness or body position change and dizziness will not have too much problem, it should be no problem. However, if you are dizzy for a long time, you should pay attention to it, because long-term dizziness or frequent dizziness may be a precursor to serious illness.

Dizziness is a syndrome that is one of the clinical manifestations of many diseases. The causes of dizziness are the following:

1, neurological disease

Such as cerebral ischemic lesions, cerebellar lesions, brain lesions, brain trauma, certain types of epilepsy. In addition, autonomic dysfunction and some patients with neurosis often feel dizzy.

2, ear disease

If the disease in the ear affects the balance, it causes dizziness.

3. Medical diseases

Such as hypertension, hypotension, various cardiovascular and cerebrovascular diseases, anemia, infection, poisoning, hypoglycemia and so on.

4, a cold

Sometimes a cold may have symptoms of dizziness.

5, cervical vertebrae degeneration

Due to long-term posture or poor sleeping position, cervical vertebra hyperplasia, deformation, degeneration, neck muscles are tight, arterial blood supply is blocked, and blood supply to the brain is insufficient. It is the main cause of dizziness, tight neck, limited flexibility, and occasional pain. Cool, heavy feeling.

6, anemia

If there is dizziness accompanied by fatigue, pale performance, the possibility of anemia should be considered. Under healthy conditions, the amount of hematopoietic tissue and the quality of hematopoiesis in the elderly have declined, and the aging of red blood cells themselves has made the utilization of iron much worse than before. Therefore, if the elderly do not pay attention to nutrition and health care, they are prone to anemia. In addition, patients with dyspepsia, peptic ulcer, gastrointestinal bleeding, and chronic inflammatory diseases can be secondary to anemia.

7, high blood viscosity

Hyperlipidemia, thrombocytosis, etc. can increase blood viscosity, slow blood flow, resulting in insufficient blood supply to the brain, prone to fatigue, dizziness, fatigue and other symptoms. There are many reasons for the high blood fat, the most important is the unreasonable structure of the diet, the patients eat a lot of high-fat, cholesterol food, but do not love sports. The incidence of this type of disease is currently on the rise.

8, cerebral arteriosclerosis

The patient feels dizzy and often suffers from insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Cerebral arteriosclerosis makes the inner diameter of the cerebral blood vessels smaller, blood flow in the brain decreases, and blood supply to the brain and insufficient oxygen supply cause dizziness.

9, heart disease

In the early stage of coronary heart disease, the symptoms are still mild. Some people may not have significant discomfort such as chest tightness, palpitations, shortness of breath, etc. They only feel headache, dizziness, weakness of limbs, difficulty in concentration, tinnitus or forgetfulness. The cause of dizziness at this time is mainly the atherosclerosis of the coronary arteries, the narrowing and narrowing of the lumen, and the ischemia and hypoxia of the heart. Insufficient blood supply to the heart can cause insufficient blood supply and cause dizziness.

10, insomnia

Clinical statistics show that the ratio of migraine patients caused by insomnia is about 65%. For this type of patient group, in the medical field, the combination of traditional Chinese medicine and western medicine, Malay, and western medicine, can achieve relatively satisfactory results.

For patients with dizziness, detailed medical history and comprehensive physical examination should be performed. If necessary, hearing examination, vestibular function examination, fundus examination should be performed, and cerebrospinal fluid examination, skull or cervical X-ray photography, electrocardiogram, EEG and Brain CT scan to find out the cause.

Diagnosis

Differential diagnosis

Persistent dizziness

Generally, ordinary acute dizziness disappears for a maximum of one to two weeks. If it is maintained for more than one month, it is persistent dizziness. It can be caused by many factors such as brain diseases, anemia, and systemic diseases.

Intermittent dizziness

Frequent intermittent dizziness is usually caused by hypotension or high blood pressure. Young people are generally caused by hypotension, and cervical spondylosis can also cause dizziness.

Mild symptoms may include: dizziness, headache, loss of appetite, fatigue, pale face, indigestion, motion sickness, etc.; severe symptoms include: erectile vertigo, cold limbs, palpitations, difficulty breathing, ataxia, ambiguous pronunciation, and even fainting Need to stay in bed for a long time. These symptoms are mainly caused by a drop in blood pressure, resulting in slow blood circulation and distal capillary ischemia, which affects the supply of oxygen and nutrients in tissue cells, and the excretion of carbon dioxide and metabolic waste. In particular, it affects the blood supply to the brain and heart.

Tension dizziness

It means that when the spirit is tense, it will be dizzy, the more nervous, the more dizzy it is. When you are nervous, you will feel dizzy. If you have a slight adjustment of your mentality, it will appear. If you try to adjust it afterwards, you will sometimes get better.

Ocular vertigo

Non-motor illusion vertigo, mainly manifested as instability, increased when the eye is excessive, and relieved after closed eyes. Dizziness lasts for a short period of time. When you look at the moving objects, you will get worse. After you close your eyes, you will ease or disappear. Often accompanied by blurred vision, decreased vision or double vision. Visual acuity, fundus, and eye muscle function tests are often abnormal, and the nervous system has no abnormalities.

Halo

Halorrhea is also called "blood phobia", which refers to the fainting phenomenon caused by the patient's blood, mainly manifested as dizziness, nausea, dizziness, palpitations, and then pale, cold sweat, cold limbs, lower blood pressure, pulse Weak, even suddenly lost consciousness.
