With the aging of the population, the incidence of benign paroxysmal positional vertigo (BPPV) and osteoporosis have been increasing year by year, and the incidence of BPPV in vertigo related diseases has also been ranked first. There are similarities in structure, formation and metabolic mechanism between bone and otolith, but there is no consistent conclusion on the relationship between BPPV and osteoporosis. This article summarizes the current situation of the research on the correlation between BPPV and osteoporosis, the common risk factors and the related co-occurring mechanisms, aiming to provide more ideas for the prevention and treatment of BPPV patients, and improve the prevention and treatment ability of the co-diseases in the elderly.
