Excessive weight gain is a major health problem in many developed countries. It is clear that obese women are at a disadvantage in terms of reproduction, and there is an increase in various complications during pregnancy, delivery, and the postpartum period. In this case, we experienced a super obese pregnant woman with a BMI of 57.5, and she was suffering from hypertension, impaired glucose tolerance, and a mental disorder. We struggled with how to manage her pregnancy and delivery but were able to succeed in delivering a live birth by cesarean section. The baby was a boy weighing 3,563g（99.9％ tile）and was diagnosed as having neonatal asphyxia with an APS score of 2/5/5（1-minute/5-minute/10-minute values）. Therefore, the neonate was treated with CPAP because of the marked acidosis in the NICU, and the umbilical artery blood gas consequently was quickly improved. Finally, the neonate was discharged on day 28 after birth. In Japan, extremely obese pregnant women are rare, and there is no standardized method for managing them, so it is necessary to respond to each case individually. Compared to normal-weight pregnant women and other obese pregnant women, extremely obese pregnant women are about twice as likely to experience maternal death or severe complications and therefore, require strict perinatal management.
