Functional Disorders of the Gastrointestinal Tract During the Pandemic of a New Coronavirus Infection

Aim. To analyze the literature data devoted to the study of the features of functional gastrointestinal diseases (FGID) during the pandemic of a new coronavirus infection.Key findings. Measures taken in connection with the pandemic of COVID-19 infection (introduction of lockdown, social isolation) leads to an increase in the level of depression and anxiety and, as a consequence, to an increase in the frequency and prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), as well as an increase in the severity of clinical symptoms of these diseases. In turn, the overcoming of COVID-19 infection contributes to an increase in the permeability of the mucous membrane of the gastrointestinal tract and the occurrence of its inflammatory changes, which lead to the development of postinfectious (postcovid) FD and postinfectious (postcovid) IBS.Conclusion. The problem of functional gastrointestinal diseases during the pandemic of a new coronavirus infection is very important and requires further research.
