When symptoms of benign paroxysmal positional vertigo (BPPV), such as persistent vomiting, occur, the first step should be to perform a repositioning treatment of the otoliths, which can gradually lead to improvement.

BPPV is a common and frequently occurring disease in the field of otolaryngology, generally caused by the movement of otoliths in the semicircular canals. This condition may lead to the patient experiencing repeated episodes of vertigo, typically triggered by rolling over or getting out of bed. The vertigo is intense, feels like the world is spinning, and lasts no more than one minute. It is also accompanied by severe nausea and vomiting, but there is no hearing loss or tinnitus. To diagnose BPPV, detailed examinations with an electronystagmograph, audiometry, and videonystagmography at a hospital are necessary.

For treatment, otolith activation and repositioning treatments are required and are generally effective. Additionally, after treatment, it is important to adjust sleeping patterns, take sufficient rest, avoid overexertion and staying up late, to gradually improve, and prevent recurrent episodes.
