Introduction
Laryngopharyngeal reflux (LPR) is an inflammatory condition of the upper aerodigestive tract tissues related to direct and indirect effect of gastroduodenal content reflux, which induces morphological changes in the upper aerodigestive tract.1 The consumption of high-fat, high- quick-release sugar, and low-protein diet and the stress (autonomic nerve dysfunction) are both factors that may favor the occurrence of pharyngeal reflux events through impairments of esophageal sphincter functioning.1,2 With the recent coronavirus disease 2019 (COVID-19) pandemic, many countries imposed lockdown to reduce the virus spread in the population. Thus, many citizens were confined to home during several weeks, which may influence positively3 or negatively4individual lifestyle and diet habits.
In the present study, we investigated the impact of lockdown on antireflux diet adherence and stress of patients treated for LPR disease.
