Caesarean Section vs. Vaginal Delivery: An Evidence-Based Review of Risks and Benefits

Abstract

Introduction: The mode of childbirth significantly influences maternal and neonatal outcomes. Vaginal delivery is considered the physiological and preferred method of birth, whereas Cesarean section (CS) is an essential surgical intervention in selected high-risk pregnancies and obstetric emergencies. Over the past few decades, the global rise in CS rates has generated concern regarding unnecessary surgical deliveries and their associated short- and long-term complications. This review aims to compare the risks, benefits, indications, and outcomes of cesarean section and vaginal delivery based on current evidence.

Materials and Methods: A narrative review was conducted using electronic databases, including PubMed, Google Scholar, Scopus, and the Cochrane Library. Articles published between 2005 and 2025 comparing maternal and neonatal outcomes of vaginal delivery and cesarean section were included. Relevant clinical guidelines, systematic reviews, observational studies, and randomized trials were analyzed.

Results: Vaginal delivery was associated with shorter hospital stay, lower healthcare costs, faster postpartum recovery, earlier mother–infant bonding, and fewer postoperative complications. It also demonstrated lower risks of infection, hemorrhage, thromboembolism, and complications in future pregnancies. However, vaginal delivery may be associated with perineal trauma, pelvic floor disorders, and fetal distress in certain situations. Cesarean section proved beneficial in obstetric emergencies such as placenta previa, obstructed labor, fetal distress, and malpresentation, significantly reducing maternal and neonatal morbidity and mortality when medically indicated. Nevertheless, Cesarean section was associated with increased risks of postoperative infection, anesthetic complications, delayed recovery, neonatal respiratory morbidity, and long-term complications including placenta accreta spectrum and uterine rupture in subsequent pregnancies.

Conclusion: Both cesarean section and vaginal delivery have distinct advantages and limitations. Vaginal delivery remains the preferred mode of childbirth in uncomplicated pregnancies, while cesarean section is a life-saving procedure when clinically indicated. The choice of delivery method should be individualized based on maternal and fetal conditions, obstetric indications, patient preferences, and evidence-based clinical judgment to optimize maternal and neonatal outcomes.
