There are many causes of dizziness in general, the most common one in clinical practice is dizziness in the elderly, which is caused by cerebral atherosclerosis and chronic lack of oxygen in brain cells, and the patient’s dizziness is usually dominated by dizziness. The patient’s dizziness is usually drowsy. Treatment can be given to the patient to combat atherosclerosis and improve blood supply. Secondly, dizziness is also seen in some patients with cervical spondylosis, especially vertebral artery type cervical spondylosis, which is generally related to changes in head position and can be accompanied by neck and shoulder pain. Dizziness can also be clinically associated with internal diseases such as anemia, especially in the elderly, where poor gastrointestinal function leads to inadequate absorption of hematopoietic materials, and the patient may experience dizziness accompanied by generalized dizziness. Dizziness can also be seen clinically in patients with coronary artery disease, such as patients with cardiac arrhythmias, who may experience dizziness and palpitations, and are advised to consult a cardiologist. Dizziness can also be seen in patients with rare diseases such as multisystem atrophy or phytodysfunction, and in some patients with anxiety and depression who suffer from chronic subjective vertigo.
