Relationship between functional constipation and anal-retentive behavior features

Constipation is the most commonly seen defecation problem related to several environmental factors. Defecation is learned in the childhood anal period in which anal characteristic features appear. Problems in the childhood anal period may affect not only characters but also defecation function. This study aimed to evaluate the relationship between constipation and anal characteristic features of participants with functional constipation.

Patients with functional constipation were included into the study according to the ROME III criteria. Patients with irritable bowel disease, slow transit constipation, outlet obstruction constipation, malignancy, and psychiatric diseases were excluded from the study. Patients filled out Personality Belief Questionnaire, Hospital Anxiety and Depression Scale, and Obsessive Belief Questionnaire. The results were compared with healthy individuals.

A total of 47 patients with functional constipation were included in the study. Avoidant, obsessive-compulsive, antisocial, narcissistic, and paranoid personality traits were found to be higher in patients with constipation than in the control group. Perfectionism/certainty, importance and control, and hospital anxiety scores were found to be higher in patients with constipation than in the control group.

Constipation may be related to several factors, such as socioeconomic environment, emotional stress, age, and diet, among others. Here, it was found that anal-retentive behavior features are prominent in functional constipation. Biofeedback, which can be regarded as psychotherapy of defecation control, can be used for treatment.
