The aim of the work is to study and describe modern concepts of functional gastrointestinal disorders. The modern Roman classification of FGIR is given, their relationship with emotions and pathological anxiety of a person is described. A comparative analysis of clinical cases of outpatient visits to an outpatient gastroenterologist for the corresponding periods from December 2019 to December 2020 is carried out. An example of such disorders in a patient is given.

The aim of the study is to evaluate and describe the frequency of referrals of patients with gastrointestinal disorders during the COVID-19 pandemic. A comparative analysis of clinical cases of outpatient access to a gastroenterologist is carried out for the corresponding periods from December 2019 to December 2021.

The aim of the study was to determine the prevalence of organic and functional pathology at an outpatient appointment with a gastroenterologist before and during the COVID-19 pandemic. An assessment of 428 outpatient clinical cases over two periods was carried out. The analysis revealed a significant increase in functional gastrointestinal pathology. During the first study period, 36% of all applied patients had functional gastrointestinal diseases, in the second period the number of patients increased to 57%.The results obtained allow us to conclude that, despite the fact that COVID-19 affects the digestive organs along with the respiratory tract, the forced isolation that arose during the pandemic and general anxiety significantly increased the growth of the functional pathology of the gastrointestinal tract, which should be taken into account when developing treatment regimens and managing gastroenterological patients.

The novel coronavirus infection (COVID-19) is accompanied, among others, by the damage of the digestive system, in particular, the formation of biliary dysfunctions. The article presents the data of observation and treatment of patients with post-covid phenomena of biliary insufficiency.
