Introduction
Obesity, one of the most common co-morbidities in women of reproductive age, contributes to infertility and obesity-related pregnancy complications. On the other hand, pregnancy is a condition in which, physiologically, the pregnant woman undergoes weight gain. Endoscopic Sleeve Gastroplasty (ESG), an organ-sparing bariatric procedure aimed to reduce gastric volume and modify gastric motility with full-thickness endoscopic sutures, may be used for the treatment of obesity in women of childbearing age.
Aims & Methods
A retrospective analysis of a prospective database was conducted to evaluate weight trajectories, the evolution of obesity-related comorbidities, and lifestyle modification in women who became pregnant after ESG.
A comparison was made between childbearing-age women who became pregnant after ESG and non-pregnant women who reached at least the 6-month follow-up after ESG.
Results
Between January 2018 and December 2021, a total of 150 childbearing-age women underwent ESG at a large Italian tertiary medical center. Out of the total, 18 patients (12,0 %) reported a desire for pregnancy associated with unsuccessful attempts in the 12 months preceding ESG.
Eleven patients (mean age 33,4±6,2 years) became pregnant after the procedure, following a mean time interval of 5,5±3,9 months. The mean preconception BMI was 31,9±4,0 kg/m² (with a mean reduction of 7,24±4,0 kg/m² after ESG). Three patients were affected by hyperinsulinemia (H-INS), while an additional patient had both H-INS and high blood pressure (HBP). Three women reported difficulty in becoming pregnant before the ESG: two were affected by PCOS.
Total body weight loss (TBWL) of at least 5% was achieved before pregnancy in all patients (73% reached a TBWL ≥ 10%).
Six out of eleven (55%) patients had weight gain in the ranges recommended by the Institute of Medicine (IOM) during pregnancy. Among the 18 women with a reported desire for maternity associated with difficult attempts in the previous 12 months, 16,6 % (3/18) managed to start and carry out a pregnancy.
TBWL (%) was 18,08±8,00, 10,35±11,53, and 12,08±8,49, at the beginning of pregnancy, at the delivery, and at the first follow-up (mean interval, 5,18±3,57 months).
No significant differences in WL, TBWL, EWL, BMI, BAROS, and QoL were found between the pregnancy and non-pregnancy groups (99 childbearing-age women) up to 24 months after ESG.
Conclusion
ESG produces adequate weight loss before pregnancy in patients with obesity and is potentially a useful treatment option for women who have difficulty becoming pregnant, such as those with PCOS. Pregnancy after ESG does not adversely affect weight loss outcomes after delivery as lifestyle changes induced by ESG are maintained after pregnancy and allow for a gradual loss of weight gained during pregnancy.
