What is dizziness?

  Dizziness, also known as vertigo, is a subjective sensory abnormality.
  It can be divided into two categories: one is rotational vertigo, which is mostly caused by the dysfunction of vestibular nervous system and cerebellum, with the feeling of tilting as the main cause, feeling that one is swaying or the scene is rotating. The second is general dizziness, which is mostly caused by some systemic diseases, with the feeling of dizziness as the main cause, feeling heavy in the head and light in the feet.
  Dizziness is a common symptom rather than an independent disease. Therefore, we can classify the diseases that cause dizziness so that we can have a deeper understanding of “dizziness”.
  1. Rotational vertigo can be divided into two categories: peripheral vertigo and central vertigo according to their causes.
  (1) Peripheral vertigo: It refers to the vertigo caused by the lesion of the vagus or vestibular nerve in the inner ear. It is common in Meniere’s disease, vaginitis, drug-related vertigo (caused by drugs such as streptomycin or gentamicin) and vestibular neuritis, etc.
  (2) Central vertigo: It refers to vertigo caused by lesions of brainstem, cerebellum, brain and spinal cord. It is commonly caused by insufficient blood supply to the vertebrobasilar artery, intracranial tumor, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo.
  2.General vertigo.
  (1) Cardiogenic vertigo: common in cardiac arrhythmia, cardiac insufficiency, etc.
  (2) Pulmonary vertigo: It can be seen in pulmonary insufficiency caused by various reasons.
  (3) Ophthalmogenic vertigo: It is commonly caused by refractive error, fundus arteriosclerosis, hemorrhage and ocular muscle paralysis.
  (4) Blood pressure vertigo: High or low blood pressure can cause vertigo.
  (5) Others: Anemia, cervical spondylosis, acute fever, gastroenteritis, endocrine disorders and neurosis can cause dizziness.
  How to register for medical consultation?
  1. Dizziness and posture are closely related, and those with neck and shoulder pain or arm pain and numbness should visit the pain department or orthopedics.
  2. unexplained dizziness or hemiplegia with numbness of the limbs should be seen at the Department of Neurology.
  3. those with dizziness accompanied by changes in blood pressure and dizziness with fever and sweating should be seen in internal medicine
  4. those who have a history of heart disease and experience dizziness with palpitations and dyspnea should consult a cardiologist.
  5. dizziness with loss of vision, mosquito sensation in front of the eyes, etc. should be seen by ophthalmology.
  6. Patients with dizziness accompanied by pallor or bruises or bruises on the skin should be seen by the Department of Hematology.
  7. Patients with sudden onset of rotational vertigo with tinnitus and no change in blood pressure should be seen at the Department of Otolaryngology.
