Downsizing pregnancy complications: a study of paired pregnancy outcomes before and after bariatric surgery

Pregnancy after Two Different Modalities of Bariatric Surgery. What to Expect?

“…This is consistent with most publications as the time lapse between bariatric surgery and pregnancy ranges from 21 to 57 months and the mean interval is more than 18 months. (23)(24)(25)(26) Recently several studies reported that pregnancy following bariatric surgery earlier than 18 months have the same impact on maternal and perinatal outcomes. (21,22,27,28) The pre-gestational BMI has a negative impact on obstetric outcome, the mean BMI of the participants at the beginning of pregnancy was 32.8±2.96 vs.29.8±2.75 in group (A) and (B) respectively (P= 0.412) which is in agreement with several studies reported that pre-gestational BMI was between 30 and 34 kg/m2.…”

“…(16,(23)(24)(25)29) The risk of abortion increases proportionately to BMI (30,31) ,and decreases following proper surgical or conservative weight loss (32)(33)(34) Our data showed 15.9% abortion rate, while it ranges between 15.3 % and 38.9% in general publications. (26,29,(34)(35)(36) Microelements and vitamins requirements are increased during pregnancy particularly following bariatric surgery, and their deficiencies can be prevented before and during pregnancy by adequate supplementations and monitoring. In the present study, iron, vitamin B12, calcium and folic acid deficiencies were 11.4%, 22.7%, 15.9%, 4.5% respectively, and the prevalence of hyperemesis gravidarum was 11.3%.…”

“…Several studies have reported a reduction in GDM after bariatric surgery (0%-8.9%), but there were insignificant differences in the prevalence of GDM when compared to women with similar BMI. (16,21,(23)(24)(25)(26)(27) Beenet et al reported 2.5% pregnancy-associated hypertensive disorders (PAHD), and 3% preeclampsia (40) , while Aricha-Tamir et al published that the incidence of PAHD was 16.5%. (26) Moreover, Cafaro et al reported significant lower incidence of gestational hypertension 8.2% and preeclampsia 2.7%.…”

(29) On the contrary, Kjaer et al (24) in a cohort study and Patel et al (21) in another study published no differences were found in the rate of preeclampsia and PAHD among women who had undergone bariatric surgery and those who had not.…”

“…The incidence of Low birth weight infants was 6.8% which is consistent with the published rates (5.2%-27.8%), and no neonatal mortality. (16,23,26,34,42) …”
