What Causes Vertigo?

Generally, vertigo may result from sudden changes in body position, chronic sleep deprivation, benign paroxysmal positional vertigo (BPPV), vestibular neuritis, or Ménière’s disease. If you experience discomfort or symptoms, it is advisable to seek timely evaluation and treatment at a reputable hospital. A detailed analysis follows:

1. Sudden Change in Body Position

Quickly standing up or turning the head after prolonged sitting or lying down can cause transient cerebral hypoperfusion and temporary dysfunction of the inner ear’s balance system, leading to brief episodes of vertigo. To minimize this, slow down when changing positions—pause briefly after rising before resuming activity—and avoid rapid head movements.

2. Chronic Sleep Deprivation

Inadequate rest places the brain’s nervous system under persistent fatigue, disrupting neural regulatory function and resulting in sensations of mental fogginess and vertigo. Maintain regular sleep-wake cycles, ensure sufficient sleep duration, avoid staying up late, and engage in moderate relaxation techniques to ease neural strain.

3. Benign Paroxysmal Positional Vertigo (BPPV)

This condition arises from dislodgement and migration of otoliths (calcium carbonate crystals) within the inner ear; head-position changes stimulate the semicircular canals, triggering episodic, brief vertigo. Treatment may include prescribed medications such as betahistine hydrochloride tablets, ginkgo biloba extract tablets, and gastrodin tablets, combined with professional repositioning maneuvers to alleviate symptoms.

4. Vestibular Neuritis

Viral infection of the vestibular nerve causes inflammatory edema, impairing vestibular sensory function and producing persistent vertigo. Under medical supervision, antiviral agents (e.g., acyclovir tablets), neurotrophic agents (e.g., mecobalamin dispersible tablets), and anti-vertigo drugs (e.g., difenidol tablets) may be administered. During the acute phase, minimize head movement and maintain bed rest.

5. Ménière’s Disease

Disruption of endolymphatic fluid metabolism leads to endolymphatic hydrops, compressing vestibular sensory receptors and causing recurrent vertigo—often accompanied by tinnitus and aural fullness. Pharmacotherapy may include flunarizine capsules, hydrochlorothiazide tablets, and citicoline sodium tablets, per physician guidance. For refractory cases, endolymphatic sac decompression surgery may be considered.

In daily life, maintain regular作息 (sleep-wake patterns), avoid excessive physical exertion and abrupt postural changes. Seek prompt medical evaluation if vertigo recurs frequently; accurate diagnosis enables targeted intervention and helps prevent fall-related injuries due to sudden vertigo episodes.
