RESUMO
OBJECTIVE: To evaluate the prevalence of constipation during pregnancy and early puerperium. DESIGN: Observational survey. SETTING: Secondary and tertiary hospital in Finland. POPULATION: Pregnant (n = 474) and postpartum (n = 403) women and a control group of 200 non-pregnant women who did not give birth in the past year. METHODS: Women reported bowel function and other gastrointestinal symptoms on a structured questionnaire using an 11-point numerical rating scale (0 = no symptom, 10 = most severe symptom) and binominal yes/no questions during the second and third trimesters and few days and 1 month after childbirth. MAIN OUTCOME MEASURE: Prevalence of constipation based on the Rome IV criteria. RESULTS: The data consist of five cohorts of women: second trimester (n = 264), third trimester (n = 210), after vaginal delivery (n = 200) or caesarean section (n = 203), and a control group (n = 200). The prevalence of constipation was 40% in pregnant women and 52% (P < 0.001) in postpartum women, which was a higher prevalence than that in the control group, where 21% had constipation (P < 0.001). A few days after delivery, the prevalence of constipation was lower after vaginal delivery (47%) than caesarean section (57%, P < 0.039). One month postpartum, the prevalence of constipation was low: 9% after vaginal delivery (P = 0.002 compared with the control group) and 15% after caesarean section. Other gastrointestinal symptoms were common; pregnant women had the highest prevalence (34%) of nausea/vomiting. CONCLUSION: The prevalence of constipation was two- to three-fold higher in pregnant women and a few days after delivery than in non-pregnant women. During puerperium, bowel function returned to or below that reported in non-pregnant women. TWEETABLE ABSTRACT: Constipation is common in pregnancy and after delivery, but bowel function returns early in puerperium.
