[Maternal and fetal outcomes in pregnancy following bariatric surgery].

BACKGROUND
Obesity is the most frequent metabolic disease in the World, and is associated with several comorbidities. Bariatric procedures arise as a promising treatment when classical approach is ineffective. Half of the operated patients are reproductive-aged women and there is evidence that obesity is related to worse maternal and fetal outcomes. Because nutritional status is affected by bariatric surgery and is a vital component during pregnancy, the aim of our study is to asses the impact of bariatric surgery on pregnancy in these patients.


MATERIAL AND METHODS
We studied 10 women and 15 pregnancies following bariatric surgery between 2003 and 2009. The visits took place every three months by an obstetrician and an endocrinologist with experience in nutrition, recording clinical features and lab work.


RESULTS
We found iron deficiency in 80% of the pregnancies, vitamin D in 46,7%, vitamin A in 20%, vitamin E in 13,3% and vitamin B12 in 26,7%. There were no complications during pregnancy, except one case of gravidic hiperemesis. There were nine deliveries without malformations, three of them were small for gestational age newborns and one suffered aspiration pneumonia. There were three stillbirths and one preterm delivery with fetal death.


CONCLUSIONS
our results show fewer complications during pregnancy in these women than obese women and similar to general population.
