Annals of Medicine and Surgery. 2018;36:129-134. doi:10.1016/j.amsu.2018.10.023. In a restrospective study from 2015-2016, 721 patients 25% of the patients were evaluated for obstetric complications. Intraoperative blood loss was significantly higher in morbidly obese group. Sixty one percent of the patients with morbidly obese had at least one co-morbidity (p<0.01) 2.

Plos One. 2019;14(2). doi:10.1371/journal.pone.0211278 International cohort study using data from UK and Australia with 1232 pregnant women. Extremely obese patients had a ninefold increase in odds of thrombotic events compared to those with a BMI <50.  Increased odds of preeclampsia/eclampsia, cesarean delivery, induction of labor, post cesarean wound infection, macrosomia. Twelve of the infants born to women in extremely obese cohort died early in neonatal period or were stillborn. 3.Rao D, Rao V.

American Journal of Obstetrics and Gynecology. 2011;204(1). doi:10.1016/j.ajog.2010.10.617 Retrospective cohort Missouri residents born between 2000-2006 included 64,272 births. Of those, 1,185 were in the Super obese category (BMI > 50). Super obesity parturients were more likely to have preeclampsia, macrosomia, neonatal hypoglycemia, increased risk neonatal morbidity (even when compared to morbidly obese women), risk of cesarean delivery regardless of parity, 31% of super obese delivered vaginally compared to 53% of obese women. Nulliparous super-obese women were significantly less likely than nulliparous obese women to have a vaginal delivery and more likely to undergo a scheduled or emergency cesarean. Dose response relationship between worsening obesity and cesarean, macrosomia, neonatal hypoglycemia, and preeclampsia. More likely to use intensive prenatal care 5.Crane JM, Murphy P, Burrage L, Hutchens D. Maternal and Perinatal Outcomes of Extreme Obesity in Pregnancy.

Extremely obese women more likely to have gestational hypertension, gestational diabetes, shoulder dystocia, cesarean section, length of stay more than 5 days, birth weight > 4000g, NICU admission, still birth, composite adverse outcomes. 6.Tonidandel A, Booth J, D’Angelo R, Harris L, Tonidandel S.
