Maternal/foetal morbidity/mortality consequent to uterine rupture, placenta previa/increta and stillbirth may occur in repeat caesarean section (CS). Elective CS before 39 weeks increases respiratory complications, hypoglycaemia, sepsis and intensive care unit admissions. Different gut colonization in neonates born by CS accounts for increased incidence of food allergy, asthma and possibly type 1 diabetes. Epigenetic changes might be responsible – among others – for childhood malignancies.
Conclusion: Decision for primary CS should take into consideration possible maternal/neonatal complications.
