The causes of intermittent dizziness may be the following: 1, insufficient blood supply to the cerebral arteries: mainly seen in middle-aged and elderly patients, patients usually have hypertension, diabetes, hyperlipidemia, and frequent smokers. These risk factors easily lead to intracranial arteriosclerosis, cerebral arteriosclerosis will lead to long-term chronic blood supply insufficiency, often occurring episodes of dizziness, headache, etc. 2, vertigo syndrome: the most common is Meniere’s disease or benign paroxysmal positional vertigo, it is recommended to go to the hospital otorhinolaryngology department to visit the hospital to decide on the specific treatment plan through the type of diagnosis.3, cervical spondylosis: theoretically, it is due to herniated intervertebral discs The theory is that it is caused by disc herniation and osteophytes, which can easily compress the corresponding blood vessels and nerves, and may also induce dizziness when the patient swings his head sharply or when his body position changes, but dizziness caused by cervical spondylosis is relatively rare.
