Prevalence and severity of bowel disorders in the third trimester of pregnancy

Bowel-related disorders are common conditions associated with pregnancy and are a cause of significant distress and healthcare burden. However, there is a lack of data in the literature about these disorders.

This study aimed to investigate bowel dysfunctions during the third trimester of pregnancy in a large cohort of women using the validated bowel domain of the Italian version of the Pelvic Floor Questionnaire for Pregnant and Postpartum Women.

This was a secondary analysis of a multicenter cross-sectional study conducted in hospitals in Italy and Italian-speaking Switzerland. Women in the third trimester of pregnancy were asked to complete the Italian Pelvic Floor Questionnaire for Pregnant and Postpartum Women.

During the study period, 927 pregnant women in the third trimester of pregnancy responded to the questionnaire and were included in the analysis. Overall bowel dysfunctions were reported by 29.6% of patients. Constipation was reported by 66.6% of pregnant women, whereas symptoms of obstructed defecation were reported by 49.9% of patients. In contrast, urgency was reported by 41.1% of patients. Incontinence to flatus and incontinence to stool were reported by 45.1% and 2.8% of patients, respectively. Moreover, age >35 years, familiarity with pelvic floor disorders, nicotine abuse, and pelvic floor contraction inability were identified as independent risk factors for at least 1 bowel symptom.

Bowel symptoms are extremely common in the third trimester of pregnancy and can greatly affect a patient's quality of life; therefore, bowel symptoms deserve to be investigated and managed properly. The use of validated questionnaires represents a precious tool to investigate functional symptoms that could be very frequent and disabling in this particular period of life for women.
