Maternal and perinatal outcomes after bariatric surgery: a case control study

Area of Science:

• Bariatric Surgery
• Maternal-Fetal Medicine
• Obesity Management

Background:

• Obesity in pregnancy is associated with adverse maternal and perinatal outcomes.
• Bariatric surgery can lead to significant weight loss and may improve pregnancy results.

Purpose of the Study:

• To compare maternal and perinatal outcomes in pregnancies of women who underwent bariatric surgery versus obese women without surgery.

Main Methods:

• Retrospective cross-sectional study of 63 post-bariatric surgery women and 73 obese controls.
• Data included demographics, surgery details, and maternal-perinatal results.
• Statistical analysis used t-tests, chi-square, and logistic regression with odds ratios (OR) and 95% confidence intervals (CI).

Main Results:

• Post-bariatric surgery women had a significantly lower BMI (26.5±4.2 kg/m2) compared to controls (34.6±3.3 kg/m2).
• Birth weight was significantly lower in the post-bariatric surgery group (P=0.017).
• Increased odds of anemia (OR=3.5) but reduced odds of macrosomia (OR=0.2) and prematurity (OR=0.3) were observed in the post-bariatric surgery group.

Conclusions:

• Women undergoing bariatric surgery experienced better maternal and perinatal outcomes.
• Bariatric surgery appears to mitigate some risks associated with obesity in pregnancy.
