The definition of constipation syndrome and its classification is presented from the modern point of view, the most widespread risk factors of constipation are reviewed. The different views on the diagnostic algorithms in patients with constipation syndrome are discussed, the need for special questionnaires use to objectively assess patient’s complaints is emphasized. Various methods of instrumental examination of colonic anatomical and functional characteristics and tests assessing the anorectal function are described. Different authors’ opinions on informative value of different diagnostic tests to assess the colonic follow-through are presented. It is concluded that approach to constipated patients is the difficult task, requiring a complex of different clinical and instrumental methods of examination. Thereby an organic etiology of constipation needs to be excluded on a first priority basis.
