Summary
Pregnancies in obese women with adjustable gastric bands were generally uncomplicated. Weight loss from gastric banding can lead to unexpected pregnancies, necessitating prompt birth control.
Area of Science:
- Bariatric Surgery
- Reproductive Health
- Maternal-Fetal Medicine
Background:
- Obesity is a significant risk factor for pregnancy complications.
- Adjustable gastric banding is a surgical treatment for obesity.
- Understanding pregnancy outcomes after gastric banding is crucial for patient counseling.
Purpose of the Study:
- To determine the outcomes of pregnancies in obese women who underwent surgical placement of an adjustable gastric band.
- To evaluate fetal and neonatal outcomes in this patient population.
Main Methods:
- Two clinical trials involving 359 obese women of reproductive potential were analyzed.
- Data on 23 pregnancies resulting from conception in 20 women were collected.
- Information was gathered via medical records and direct patient contact.
Main Results:
- Eighteen of 23 pregnancies resulted in full-term deliveries, with 14 vaginal and 4 cesarean births.
- Mean birth weight was 3676 g; five women experienced weight loss during pregnancy without adverse effects.
- Gastric band adjustments for nausea/vomiting were sometimes associated with excessive weight gain.
Conclusions:
- Pregnancies following adjustable gastric banding in morbidly obese women were largely uncomplicated.
- Band adjustments for symptoms can impact weight management; prophylactic adjustments may lead to excessive gain.
- Effective contraception counseling is vital for obese women undergoing gastric banding due to potential unexpected pregnancies.
