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.
