Dizziness caused by turning the head to the left while lying down may be caused by benign paroxysmal positional vertigo, cervical spondylosis, transient ischemic attack and so on.
1. Benign paroxysmal positional vertigo: when the head suddenly turns to the left while lying down, it is likely to cause otoliths to fall off into the semicircular canals, which may cause dizziness, and may be accompanied by nystagmus, a sense of rotation of the eyes, and other manifestations.
2. Cervical spondylosis: especially in patients with cervical disc herniation, lying down and suddenly turning the head to the left is likely to lead to the protruding cervical discs compressing the local blood vessels, causing insufficient blood supply to the vertebral basilar arteries, which may cause dizziness.
3. Transient cerebral ischemic attack: common in the presence of cerebral atherosclerosis, hypertension, hyperlipidemia and other underlying diseases of the people, lying down when the head suddenly turned to the left, is likely to cause transient cerebral ischemic attack, may show dizziness symptoms.
It is recommended to consult a doctor as soon as possible to clarify the cause of dizziness while lying down, and then give targeted treatment.
