Core Tip

Core Tip: Reflux hypersensitivity (RH) significantly contributes to heartburn. However, its underlying mechanisms are not fully comprehended. This retrospective study examined data from 92 patients diagnosed with RH and 104 healthy controls to explore clinical characteristics and potential risk factors. The results demonstrate that weakly acidic reflux and nonacidic reflux are integral to the pathophysiology of RH. Furthermore, extraesophageal symptoms were correlated with a younger age and elevated levels of nonacidic reflux. Independent risk factors identified for RH encompass age, the existence of a hiatal hernia, and anxiety. These findings highlight the intricate relationship between reflux subtypes and psychological factors in RH, offering new perspectives for individualized diagnostic and therapeutic strategies.
