Prospects for the use of biomarkers in the diagnosis of irritable bowel syndrome

Irritable bowel syndrome is a chronic functional disorder of the intestine, manifested by altered intestinal habits and recurrent abdominal pain in combination with two or more criteria: association with defecation, association with a change in the frequency of defecation, association with a change in the appearance of the stool. To date, IBS remains a diagnosis of exclusion that needs to be differentiated from a wide range of organic diseases. In recent years, a large number of publications have appeared on the research of etiopathogenesis, diagnosis and treatment of IBS. This literary review highlights the problems of searching for biomarkers of IBS as a way to solve the problem of diagnosis of this pathology and understanding the causes of its occurrence.
