Women with preconception BMI >50 kg/m² smoked, developed gestational diabetes and pre-eclampsia, and needed induction of labor more frequently than mothers with BMI ≤50 kg/m². Examination of the case records showed that many attempted vaginal delivery without epidural analgesia, 21{\%} needed an emergency cesarean section (compared with 12{\%} among women with BMI ≤50 kg/m²), and 25{\%} underwent general anesthesia in this context. Many neonates were macrosomic and 34{\%} needed neonatal intensive care and early feeding compared with 6{\%} of neonates from women with BMI ≤50 kg/m². Women with an extremely high preconception BMI develop more pregnancy complications and their neonates appear affected by this as well.",
