Dizziness can be caused by a variety of causes, most commonly in febrile diseases, hypertension, cerebral arteriosclerosis, craniocerebral trauma syndrome, and neurosis. In addition, it is also seen in anemia, arrhythmia, heart failure, hypotension, drug poisoning, uremia, asthma and so on. Being dizzy is also an early symptom of depression.
Dizziness can occur alone, but often with headaches.

Occasionally dizziness or posture changes and dizziness will not have much problem. If you feel dizzy for a long time, it may be a sign of serious illness, and you should pay attention to it.
Common Causes
1. Neurological disease

Such as cerebral ischemic lesions, cerebellar lesions, brain lesions, brain trauma, certain types of epilepsy. In addition, patients with autonomic dysfunction and certain neurological disorders often feel dizzy.
2. Ear disease
If the disease in the ear affects the balance, it causes dizziness.

3. Cardiovascular disease & others

Such as hypertension, hypotension, a variety of cardiovascular and cerebrovascular diseases, anemia, infection, poisoning, low blood sugar and so on.
4. Cold

Sometimes colds may have dizziness.

5. Cervical bone degeneration

Due to prolonged posture or poor sleeping posture, cervical spine hyperplasia, deformation, degeneration, neck muscle tension, blocked blood supply to the brain, is the main reason for dizziness. Neck tightness, limited flexibility, occasional pain, scalp fingers numb, cold, shoulder pain, heavy feeling, and even accompanied by nausea, palpitation and other symptoms.

6. Anemia

If dizziness is accompanied by fatigue and pale appearance, you should consider the possibility of anemia. Patients with dyspepsia, peptic ulcer, gastrointestinal bleeding, and chronic inflammatory disease can all have secondary anemia.
7. High blood viscosity
Hyperlipidemia, thrombocytosis, etc. can increase blood viscosity, blood flow is slow, resulting in insufficient blood supply to the brain, prone to fatigue, dizziness, fatigue and other symptoms. At present, the incidence of this type of disease has an upward trend.

8. Cerebral arteriosclerosis

The patient feels dizzy and often suffers from insomnia, tinnitus, emotional instability, forgetfulness, and numbness of the extremities. Cerebral arteriosclerosis makes the inner diameter of the cerebral blood vessels smaller, the blood flow in the brain decreases, resulting in cerebral blood supply, lack of oxygen, causing dizziness. Clinical features are dizziness, sleep disturbances, memory loss three symptoms, as well as the top occipital headache, snoring, emotional sensation of speech disorders and other symptoms, the general condition of the slow development of this kind of dizziness is characterized by easy to appear when the posture change or Increase.

They only feel headaches, dizziness, weakness in their limbs, difficulty in concentrating their spirits, tinnitus or forgetfulness. Cardiac arrest, paroxysmal tachycardia, paroxysmal atrial fibrillation, and ventricular fibrillation can lead to acute cerebral ischemia, manifesting dizziness, vertigo, stomach upset, syncope, and so on.
10. Drug poisoning

Intoxication with streptomycin, neomycin, kanamycin, and gentamycin is more common. In addition to dizziness, patients have sensorineural deafness due to vertigo and cochlear nerve damage. Chronic lead poisoning is mostly characterized by neurasthenic syndrome, with dizziness, headache, insomnia, forgetfulness, fatigue, and more dreams as the main symptoms, as well as reduced body temperature and loss of appetite.

11. Functional hypoglycemia

Can also cause dizziness, palpitation, feelings of weakness, there may be tremors in the fasting or exertion, sometimes convulsions, loss of consciousness. In times of emotional stress or hyperventilation, due to increased CO2 emission, respiratory alkalosis can occur, brain cells become hypoxic, causing dizziness, fatigue, and the patient feels coolness and tingling on the face and hands.
Common Tests & Exams

Doctors will run physical exam. Furthermore, there’re a few tests and exams that doctors may order when necessary, including hearing exam, vestibular function tests, fundus exam, cerebrospinal fluid exam, head or cervical X-ray, ECG, electroencephalograms, and cranial CT scans.
