The causes of dizziness after lying down and standing up include vertebral artery-type cervical spondylosis, paroxysmal benign positional vertigo and postural hypotension.
1. Vertebral artery-type cervical spondylosis: after the onset of this disease, due to degenerative changes in the cervical spine, herniated intervertebral discs and other compression of the vertebral arteries, which may lead to insufficient cerebral blood supply when changing body position, the patient will have dizziness and vertigo symptoms after lying down and standing up.
2. Paroxysmal benign positional vertigo: after changing the head position, dizziness and vertigo will occur when lying down or standing up due to the movement of the inner ear otolith.
3. Positional hypotension: when the blood pressure drops suddenly after the patient changes the position, it causes insufficient blood supply to the brain, which is manifested as dizziness and vertigo and other symptoms.
The symptoms of dizziness and lightheadedness after changing positions suggest timely medical treatment to clarify the cause and reasonable treatment under the guidance of the doctor.
