The present study investigated the outcomes of pregnancies and births after bariatric surgery (BS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>All patients who gave birth at our clinic between 2018 and 2023 were included in the study. Individuals who had undergone BS previously were identified using the hospital database, and their medical birth records were obtained for data on pregnancy, delivery, and perinatal results. The results of women who had undergone BS previously were analyzed by comparing them with other pregnancies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 298 women who had undergone BS previously and 4,374 women who had not undergone surgeries were included in the study. The BS group had higher rates of abortion (<jats:italic>p<\/jats:italic>\u202f=\u202f0.009) and IVF history (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001). Additionally, the incidence of pregnancy-induced hypertension (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001), preeclampsia (<jats:italic>p<\/jats:italic>\u202f=\u202f0.04), gestational diabetes (GDM) (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001), premature birth (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001), cesarean delivery (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001), and small for gestational age (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001) was significantly higher in the BS group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Given the potential hazards associated with obesity in women of reproductive age, BS may be seen as a prudent course of therapy. Our study concluded that pregnancy prognosis is closely correlated with BMI at the time of pregnancy. Previous research revealed similar findings between groups in terms of pregnancy prognosis and pregnancy complications in obese and extremely obese patient groups.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2025.1609344","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T05:14:20Z","timestamp":1749618860000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of pregnancy outcomes in patients with a history of bariatric surgery"],"prefix":"10.3389","volume":"12","author":[{"given":"Ufuk","family":"Atlihan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Onur","family":"Yavuz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Can","family":"Ata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huseyin Aytug","family":"Avsar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selcuk","family":"Erkilinc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,6,11]]},"reference":[{"key":"ref1","first-page":"1377","article-title":"Trends in adult body-mass index in 200 countries from 1975 to 2014: a pooled analysis of 1698 population-based measurement studies with 19\u00b72 million participants","volume-title":"Lancet","year":"2016"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1025","DOI":"10.1016\/S2213-8587(16)30217-0","article-title":"Preconceptional and maternal obesity: epidemiology and health consequences","volume":"4","author":"Poston","year":"2016","journal-title":"Lancet Diabetes Endocrinol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"2286","DOI":"10.1001\/jama.2008.641","article-title":"Pregnancy and fertility following bariatric surgery: a systematic review","volume":"300","author":"Maggard","year":"2008","journal-title":"JAMA"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD003641","article-title":"Surgery for weight loss in adults","volume":"2014","author":"Colquitt","year":"2014","journal-title":"Cochrane Database Syst Rev"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"g3961","DOI":"10.1136\/bmj.g3961","article-title":"BS for obesity and metabolic conditions in adults","volume":"349","author":"Arterburn","year":"2014","journal-title":"BMJ"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"172437","DOI":"10.1001\/jama.292.14.1724","article-title":"BS: a systematic review and meta-analysis","volume":"292","author":"Buchwald","year":"2004","journal-title":"JAMA"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"1937","DOI":"10.1007\/s11695-020-05207-7","article-title":"Bariatric surgery survey 2018: similarities and disparities among the 5 IFSO chapters","volume":"31","author":"Angrisani","year":"2021","journal-title":"Obes Surg"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"1723","DOI":"10.1001\/jama.2018.3060","article-title":"Trends in obesity and severe obesity prevalence in US youth and adults by sex and age, 2007-2008 to 2015-2016","volume":"319","author":"Hales","year":"2018","journal-title":"JAMA"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"4587064","DOI":"10.1155\/2018\/4587064","article-title":"Management of pregnant women after bariatric surgery","volume":"2018","author":"Harreiter","year":"2018","journal-title":"J Obes"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"45","DOI":"10.1016\/j.ejogrb.2014.07.015","article-title":"Maternal and neonatal outcomes in women undergoing BS: a systematic review and meta-analysis","volume":"181","author":"Galazis","year":"2014","journal-title":"Eur J Obstet Gynecol Reprod Biol"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"e1002656","DOI":"10.1371\/journal.pmed.1002656","article-title":"Delivery outcomes in term births after bariatric surgery: population-based matched cohort study","volume":"15","author":"Stephansson","year":"2018","journal-title":"PLoS Med"},{"key":"ref12","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1016\/j.bpobgyn.2014.04.015","article-title":"Pregnancy and neonatal outcome after BS","volume":"29","author":"Willis","year":"2015","journal-title":"Best Pract Res Clin Obstet Gynaecol"},{"key":"ref13","doi-asserted-by":"publisher","first-page":"2354","DOI":"10.1007\/s11695-017-2661-2","article-title":"Pregnancy after bariatric surgery: national survey of obstetrician\u2019s comfort, knowledge, and practice patterns","volume":"27","author":"Smid","year":"2017","journal-title":"Obes Surg"},{"key":"ref14","doi-asserted-by":"publisher","first-page":"S14","DOI":"10.2337\/dc20-S002","article-title":"2.
