As soon as you lower your head and then raise it again, you get dizzy, which may be caused by otolithiasis, cervical spondylosis, or staying up all night and overworking.
1. Otolithiasis: If there is typical vertigo such as spinning of vision when you look down and up, and the vertigo lasts for a relatively short period of time, not more than a minute, then this situation is likely to be caused by otolithiasis. Otolithiasis is also known as benign paroxysmal positional vertigo, which is vertigo induced by particles of otoliths falling off and rolling in the semicircular canals of the inner ear.
2. Vertebral artery cervical spondylosis: Because the compressed vertebral artery affects the blood supply to the brainstem and cerebellum, it may also induce dizziness, lightheadedness, and unsteady walking. The cerebellum and brainstem contain many nerve nuclei related to the sense of balance. These patients are often accompanied by stiffness and soreness in the neck, and numbness and weakness in the upper limbs.
3. Prolonged late nights, overwork, and physical weakness may induce spasms of the cerebral blood vessels or fluctuations in blood pressure, which may also lead to dizziness when lowering the head and raising it again. However, this condition will be gradually relieved after resting and exercising.
If the above symptoms continue to be unrelieved and the attacks are still frequent, it is recommended that the patient go to the hospital for an interview with a doctor to determine the cause and give targeted treatment.
