Transient vertigo may be related to postural hypotension, otolithiasis, transient ischemic attack, cervical spondylosis, etc. One should consult a doctor in time to find out the cause of the disease and treat it. 1. Postural hypotension: Due to prolonged lying or squatting position, blood is stagnated in the lower limbs, and the venous blood return is insufficient after suddenly standing upright, the blood supply to the brain is insufficient, which triggers postural hypotension, which can be manifested as transient vertigo and blackout. No treatment is needed, but patients should pay attention to get up slowly after squatting for a long time to avoid triggering postural hypotension. 2. Otolithiasis: also known as benign paroxysmal positional vertigo, manifested as transient, transient vertigo when the head is in a particular position, usually lasting for tens of seconds. Generally, otoliths need to be repositioned under the operation of specialized doctors, or machine repositioning treatment. 3. Transient ischemic attack: Transient ischemia of the posterior circulation can lead to transient vertigo attacks and blackouts. Neurological treatment such as controlling blood pressure and blood sugar and adjusting blood lipid should be performed to treat the primary disease. 4. Cervical spondylosis: Especially when there is vertebral artery type of cervical spondylosis, turning the neck will lead to increased pressure on the vertebral artery and insufficient blood supply, resulting in transient vertigo or even fainting. If patients find the symptoms of transient vertigo, they should pay attention to it and seek medical treatment in time. It is forbidden for patients to take medication on their own to avoid serious sequelae.
