title: Pregnancy outcomes following bariatric surgery.
abstract: OBJECTIVE
  To compare pregnancy outcomes postbariatric surgery for women who remain obese at conception to those who were not obese.
  
  
  METHODS
  From a database of women who received outpatient perinatal services, we identified women with a history of bariatric surgery who are currently pregnant with a singleton gestation. Available maternal characteristics and pregnancy outcomes were compared between women whose prepregnancy body mass index (PPBMI) remained in the obese range (≥30 kg/m(2)) and those with a PPBMI of <30 kg/m(2) using Fisher exact test, independent Student's t test, and Mann-Whitney U test statistics.
  
  
  RESULTS
  Of the 102 women identified, 52 (51%) were obese and 50 (49%) were not obese at conception. No differences were observed in maternal age, marital status, years from surgery to delivery, development of gestational diabetes, gestational age at delivery, neonatal intensive care unit (NICU) admission, or nursery days. Maternal obesity (≥30 kg/m(2)) postbariatric surgery was associated with higher rates of cesarean delivery (63.5% vs. 36.0%, p=0.010) and development of pregnancy-related hypertension (36.5% vs. 8.0%, p=0.001) compared to nonobese women (<30 kg/m(2)).
  
  
  CONCLUSIONS
  Postbariatric surgery, an optimal goal should be to achieve a nonobese weight status before conception to reduce maternal complications, such as pregnancy-related hypertension and cesarean delivery.
