BACKGROUND: Reflux hypersensitivity (RH) constitutes roughly 14% of patients with heartburn and 34% of those with refractory heartburn, yet it is inadequately comprehended.
AIM: To investigate the clinical characteristics and risk factors associated with RH.
METHODS: We conducted a retrospective analysis of 109 patients with RH and 384 healthy controls from three medical centers between January 2022 and December 2023. Comprehensive data encompassing symptoms, motility, impedance-pH monitoring, and psychological evaluations were collected.
RESULTS: RH patients encountered a greater frequency of weakly acidic reflux (WAR) events compared to acidic reflux or nonacidic reflux (NAR) events. Upright reflux time (1.22%) exceeds supine reflux time (0.54%) (P < 0.05). Extraesophageal symptoms were more prevalent among younger patients and those with elevated NAR (P < 0.05). The acidic reflux, WAR, NAR, and peristaltic contraction break length in male patients exceeded those in female patients (P < 0.05). Age [odds ratio (OR) = 5.633], hiatal hernia (OR = 13.103), and anxiety (OR = 17.342) constituted independent risk factors for RH.
CONCLUSION: WAR and NAR are pivotal in RH. Patients with increased NAR are more likely to experience extraesophageal symptoms. Age, hiatal hernia, and anxiety are significant independent risk factors for RH.
