Surgically induced metabolic changes benefit mother and child, but can also lead to some adverse pregnancy outcomes. Knowledge about glucose homeostasis in these pregnancies could elucidate some of the mechanisms behind these outcomes. This review focusses on glucose homeostasis and birth weight. Methods: We considered papers dealing with glucose homeostasis, gestational diabetes mellitus (GDM) and\/or small-for-gestational age infants (SGA) in pregnancies with a history of sleeve gastrectomy (SG) or Roux-en-y gastric bypass (RYGB). Results: Since an OGTT is unreliable to diagnose GDM in a pregnancy after bariatric surgery, the true incidence of GDM is unknown. Alternative screening strategies are needed. Furthermore, these pregnancies are marked by frequent hypoglycemic events as well as wide and rapid glycemic excursions, an issue that is very likely underreported. There is a lack of uniformity in reporting key outcomes and a large variation in study design and control population. Conclusion: Alteration of glucose homeostasis in a pregnancy after bariatric surgery should be further studied using unequivocal definition of key concepts. Glycemic control may prove to be a modifiable risk factor for adverse pregnancy outcomes such as the delivery of an SGA baby.<\/jats:p>","DOI":"10.3390\/jcm9092732","type":"journal-article","created":{"date-parts":[[2020,8,24]],"date-time":"2020-08-24T10:37:32Z","timestamp":1598265452000},"page":"2732","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Glucose Homeostasis, Fetal Growth and Gestational Diabetes Mellitus in Pregnancy after Bariatric Surgery: A Scoping Review"],"prefix":"10.3390","volume":"9","author":[{"given":"Ellen","family":"Deleus","sequence":"first","affiliation":[{"name":"Department of Abdominal Surgery, University Hospital Gasthuisberg, KU Leuven, Herestraat 49, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart","family":"Van der Schueren","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, University Hospital Gasthuisberg, KU Leuven, Herestraat 49, 3000 Leuven, Belgium"},{"name":"Department of Chronic Diseases, Metabolism and Ageing, KU Leuven, Herestraat, 49, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7837-4684","authenticated-orcid":false,"given":"Roland","family":"Devlieger","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology, University hospital Gasthuisberg, KU Leuven, Herestraat 49, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Lannoo","sequence":"additional","affiliation":[{"name":"Department of Abdominal Surgery, University Hospital Gasthuisberg, KU Leuven, Herestraat 49, 3000 Leuven, Belgium"},{"name":"Department of Chronic Diseases, Metabolism and Ageing, KU Leuven, Herestraat, 49, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3325-0263","authenticated-orcid":false,"given":"Katrien","family":"Benhalima","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, University Hospital Gasthuisberg, KU Leuven, Herestraat 49, 3000 Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1056\/NEJMoa1614362","article-title":"Health effects of overweight and obesity in 195 countries over 25 years","volume":"377","author":"Afshin","year":"2017","journal-title":"N.
