Pregnancy outcomes following bariatric surgery

Area of Science:

• Bariatric Surgery Outcomes
• Maternal-Fetal Medicine
• Obesity in Pregnancy

Background:

• Bariatric surgery is a common intervention for obesity.
• Pregnancy following bariatric surgery requires careful monitoring.
• The impact of pre-pregnancy obesity on outcomes in post-bariatric surgery patients is not fully understood.

Purpose of the Study:

• To compare pregnancy outcomes between women who remain obese (BMI ≥30 kg/m²) and those who are non-obese (BMI <30 kg/m²) after bariatric surgery.
• To identify specific maternal complications associated with obesity at conception in this population.

Main Methods:

• Retrospective analysis of pregnant women with a history of bariatric surgery.
• Comparison of maternal characteristics and pregnancy outcomes between obese (≥30 kg/m²) and non-obese (<30 kg/m²) pre-pregnancy BMI groups.
• Statistical analysis using Fisher exact test, independent Student's t test, and Mann-Whitney U test.

Main Results:

• Of 102 women, 52% were obese and 49% non-obese at conception.
• No significant differences in maternal age, gestational diabetes, delivery gestational age, or NICU admissions.
• Maternal obesity was linked to significantly higher rates of cesarean delivery (63.5% vs. 36.0%) and pregnancy-related hypertension (36.5% vs. 8.0%).

Conclusions:

• Achieving a non-obese weight status (BMI <30 kg/m²) before conception is an optimal goal for women postbariatric surgery.
• This strategy can help reduce maternal complications such as pregnancy-related hypertension and the need for cesarean delivery.
• Emphasizes the importance of pre-conception counseling and weight management in this patient group.
