Weight LossOutcomes of Early Pregnancy Versus Late Pregnancy After LSG

The timing of pregnancy following laparoscopic sleeve gastrectomy (LSG) and its implications remain debated in literature.A recent study assessed midterm weight loss outcomes in women who became pregnant at different intervals after undergoing LSG.

This was a retrospective study that analyzed 53 women who met the inclusion criteria. Demographic and anthropometric data were collected. Women who conceived within 12 months of LSG were categorized as the early group (EG), while those who conceived after 12 months were categorized as the late group (LG).

No differences were observed between the groups in obesity-related diseases or the number of previous pregnancies. At the time of LSG, the EG had a higher weight and body mass index (BMI). The mean interval between LSG and conception was 6.7 ± 3.2 months for the EG and 20 ± 5.2 months for the LG. The EG exhibited lower gestational weight gain (GWG). No differences were found in the number of small for gestational age (SGA) births or overall gestational weight. Within the first 2 years post-LSG, the LG had a higher percentage of total weight loss (%TWL) and percentage of excess BMI loss (%EBMIL). However, after 5 years, %TWL and %EBMIL differences were not statistically significant between the groups.

From the findings, it was concluded that conception within 12 months of LSG may impede short-term weight loss but does not significantly affect weight loss outcomes after 5 years of follow-up.
