Dizziness when lying down to sleep may be related to intracranial lesions, cervical spondylosis, benign paroxysmal positional vertigo, and other diseases.
1. Intracranial lesions: some intracranial lesions, such as cerebrovascular disease, ventricular tumors, etc., due to changes in intracerebral hemodynamics caused by the lesions, dizziness may occur when lying down.
2. Cervical spondylosis: when there are herniated intervertebral discs and spinal stenosis in the cervical spine of patients, it may lead to compression of the vertebral artery of the brain and cause insufficient cerebral blood supply, which manifests as episodic vertigo symptoms.
3. Benign paroxysmal positional vertigo: it is a relatively common position-induced vertigo, and patients often experience dizziness, nausea, and spinning when their positions change, such as when they lie down, get up, turn over, turn their heads, or lower their heads, and the vertigo usually lasts for a short period of time, and is often self-limiting.
4. Other diseases: other neurological diseases, such as vestibular neuronitis, vestibular migraine can also appear when lying down on the sky, dizziness symptoms.
Dizziness may also be caused by other reasons. If the symptoms are serious or frequent, you should go to the hospital as soon as possible, complete the relevant examinations, and standardize the treatment after clarifying the cause of the disease.
