Obesity is a major global growing public-health problem. About 25% of women are suffering from obesity, of which one-third are at child bearing age (from 18 to 45 years old). Laparoscopic Sleeve Gastrectomy (LSG) is one of the main bariatric surgeries known to be safe and effective in weight reduction. However, little is known about pregnancy and neonate outcomes post LSG. A retrospective study was done in Riyadh, KSA. Data were collected from two centers in King Khalid University Hospital (KKUH) and Specialized Medical Center (SMC). From a total of 145 pregnancies in 106 females, there were 21 spontaneous abortions (14.5%), 13 preterm deliveries (10%), 45 Caesarean sections (36.3%) and six females having complications during their pregnancy (4.2%). Two cases ended up with the death of the neonate (1.6 %). Also, two cases had abnormalities (1.6 %). Thirty-eight neonatal births with a weight less than 2.5 kg (30.6%) were observed and the mean birth weight was calculated to be 2.6 kg (S.D ± 0.6 kg). After comparing our results with literature, we can conclude that females post LSG have complications on pregnancy and neonate much less than obese females because of weight reduction. On the other hand, LSG is associated with a high rate of low birth in Saudi population, but the cause is still not clear. A good follow-up post-LSG and nutritional advice could improve the outcome.
