Hemorrhoids and related complications in primigravid pregnancy

Abstract

Purpose: To identify the effect of pregnancy on the development of external hemorrhoids and constipation. Subjects and methods: This pilot study involved 61 primigravid women without a history of perianal diseases. Each patient was examined and filled a questionnaire between the 11th and 14th gestational week prior to prenatal screening tests. Patients were re-examined and questioned in relation to perianal symptoms and hemorrhoidal changes again in the 24th and 37th gestational weeks. Results: A total of 5, 8, and 11 women had symptomatic external hemorrhoids with or without perianal complications in the 11–14th, 24th, and 37th gestational weeks, respectively. Meanwhile, 27, 25, and 29 women complained about constipation in the 11–14th, 24th, and 37th gestational weeks, respectively. Only 4 (6.6%) patients experienced painful hemorrhoids. The overall morbidity rate was 18% (11 cases). We found a statistically significant relationship between external hemorrhoids/perianal complications and gestation-induced constipation through logistic regression analysis (p < 0.001). Conclusion: Various risk factors and biological explanations exist for the high frequency of hemorrhoids during pregnancy. Because participants were primigravid women without a history of perianal complaints, findings suggest a direct effect of pregnancy itself on the development of external hemorrhoids/perianal symptoms.
