Introduction: Maternal obesity (MO) increases the risk of gestational and neonatal complications. Bariatric surgery (BS) is currently the most effective long-term treatment of MO. The sustained weight loss after BS reduces the risk of maternal comorbidities during pregnancy. Nevertheless, BS is associated with an important risk of nutrients deficiency, and some data indicate that might increase the risk of prematurity and low birth weight. The objective of the present study is to evaluate the evolution of the pregnancy ending with a living child following bariatric surgery in obese females following BS in our center.
Methods: We performed a retrospective observational study by reviewing the medical records of MO females that underwent BS between January 2004 and October 2016 in our center and that had a pregnancy that finalized with a living child.
Results: A total of 20 pregnancies that finalized with a living child were registered. All the pregnancies were spontaneous, after 3.4±2.9 years following BS. The BMI pre-BS was 43.9±4.7 kg/m2. At the moment of conception the maternal mean age was 33±4.6 years and the BMI was 30.6±4.9 kg/m2. The course of gestation was normal and full term in all cases. Of all the patients, 8 (40%) underwent Sleeve gastrectomy (SG) and 12 (60%) underwent Roux-en-Y gastric bypass (RYGB). Gestacional diabetes was registered in 3 (15%) cases, similar to the general population. The birth weight of the children was 3032±3.81 g. The incidence rate of small-for-gestational age birth was 25%, higher than 10% in the general population. There were no significant differences between the two surgical techniques regarding the evolution of pregnancy and the need of vitamin supplements. No neonatal complications were observed.
Conclusion: In our study BS did not increased the risk of prematurity or complications during pregnancy. We found an increased risk of small-for-gestational-age compared with general population.
