Lying in bed and turning over dizziness for a few seconds and return to normal need to be alert to cervical spondylosis, benign paroxysmal positional vertigo, ischemic encephalopathy and other diseases. Dizziness caused by physiological factors will usually subside on its own.
1. Cervical spondylosis: some patients suffer from cervical spondylosis, especially vertebral artery cervical spondylosis, when lying in bed and turning over the cervical spine around the neurovascular compression, which will lead to impeded blood circulation, dizziness, adjust the position of the blood supply to improve the symptoms of relief. It can be clearly diagnosed by cervical spine MRI.
2. Benign paroxysmal positional vertigo: Benign paroxysmal positional vertigo is also known as otolithiasis. When the patient turns over in bed, due to head movement, it may cause otoliths to fall off and enter the semicircular canals, and vertigo symptoms will appear. Moreover, this kind of vertigo is mostly related to body position, with intense symptoms and short duration, which can be clarified through positional test and other examinations.
3. Posterior circulation ischemia: Dizziness may be caused by the narrowing of the vertebrobasilar artery, which aggravates the insufficiency of blood supply to the brain and causes vertigo symptoms when the position is changed. After adjusting the position, the blood supply improves and the symptoms are relieved. It can be diagnosed by transcranial Doppler ultrasonography and cranial MRA.
Dizziness that returns to normal after a few seconds of turning over in bed can also be caused by other reasons. Usually, you need to rest more and ensure sufficient sleep, and if the symptoms do not subside for a long time, you need to consult a doctor in a timely manner in order to avoid delaying your condition.
