Elderly people get dizzy when they lie down instantly may be caused by benign paroxysmal positional vertigo, cervical spine degeneration, insufficient cerebral blood supply and other reasons.
1. Benign paroxysmal positional vertigo: the otolith can fall to the balance structure of the inner ear due to the change of position while lying down, resulting in vertigo, nystagmus, nausea and vomiting and other symptoms.
2. Degenerative changes of cervical vertebrae: Older people may have degenerative changes of cervical vertebrae as they grow older, which may lead to herniated cervical discs, stiffness of neck and shoulder muscles, etc. The vertebral arteries may be compressed after lying down, resulting in insufficient supply of blood to the cerebral basilar artery, which leads to insufficient supply of blood to the brain and insufficient supply of oxygen, and thus dizziness may occur in an instant.
3. Insufficient blood supply to the brain: For example, patients with atherosclerosis will have their blood flow slowed down, easily deposited in the inner wall of the blood vessels to form plaques, atherosclerosis, etc., which in turn will cause the narrowing of blood vessels, resulting in insufficient blood supply to the brain and causing dizziness. The slowing of blood flow may aggravate the symptoms when lying down and changing body position.
Elderly people who lie down instantly dizziness is caused by a variety of reasons, it is recommended that patients seek medical attention in a timely manner to clarify the causes of targeted treatment.
