This study included patients diagnosed with BPPV who received treatment at Srinagarind Hospital, Khon Kaen University, Thailand between January 1, 2020, and January 1, 2022. This study evaluated the recurrence rate, and associated risk factors for BPPV recurrence in Thailand. A total of 376 patients met the inclusion criteria, with the majority being female (75.3%). The mean age of the patients was 58.09 ± 13.10 years. The most commonly affected site was the posterior semicircular canal. Recurrence of BPPV was observed in 33 patients (8.8%), with the highest recurrence rate (30.3%) occurring within the first 6 months. Risk factor analysis showed that older adults were 2.91 times more likely to experience recurrence within the first year compared to younger adults (95% CI: 1.12–7.59, P = 0.029). Further analysis revealed that patients experiencing recurrence within the first year were 5 times more likely to be older adults than younger adults (95% CI: 1.04–24.03, P = 0.045). Gender, along with comorbid conditions like diabetes, hypertension, and a history of head trauma, were not found to be significant risk factors for recurrence. https://biomedpharmajournal.org/vol18no1/recurrence-rates-and-risk-factors-for-benign-paroxysmal-positional-vertigo-insights-from-a-large-single-institution-epidemiological-study/ Benign paroxysmal positional vertigo Positional vertigo Recurrence rate Risk factor Vertigo
