Compared with women with a healthy pre-pregnancy weight, women with obesity are at increased risk of miscarriage, gestational diabetes, preeclampsia, venous thromboembolism, induced labour, caesarean section, anaesthetic complications and wound infections, and they are less likely to initiate or maintain breastfeeding. Babies of obese mothers are at increased risk of stillbirth, congenital anomalies, prematurity, macrosomia and neonatal death. Intrauterine exposure to obesity is also associated with an increased risk of developing obesity and metabolic disorders in childhood. This article reviews the prevalence of obesity in pregnancy and the associated maternal and fetal complications. Recommendations and suggestions for pre-conception, antenatal and postnatal care of women with obesity are presented, and current research in the UK and future research priorities are considered. <\/jats:p>","DOI":"10.1258\/om.2009.090009","type":"journal-article","created":{"date-parts":[[2009,5,22]],"date-time":"2009-05-22T18:40:13Z","timestamp":1243017613000},"page":"52-62","source":"Crossref","is-referenced-by-count":70,"title":["Obesity in pregnancy: risks and management"],"prefix":"10.1258","volume":"2","author":[{"given":"Kate J","family":"Fitzsimons","sequence":"first","affiliation":[{"name":"Confidential Enquiry into Maternal and Child Health, Chiltern Court, 188 Baker Street, London NW1 5SD"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo","family":"Modder","sequence":"additional","affiliation":[{"name":"Confidential Enquiry into Maternal and Child Health, Chiltern Court, 188 Baker Street, London NW1 5SD"},{"name":"UCLH NHS Foundation Trust, 250 Euston Road, London NW1 2PG"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian A","family":"Greer","sequence":"additional","affiliation":[{"name":"Hull York Medical School, University of York, Heslington, York YO10 5DD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,5,22]]},"reference":[{"key":"bibr-OM-09-0009-CPC1","volume-title":"Obesity: Preventing and managing the global epidemic","author":"World Health Organization","year":"2000"},{"key":"bibr-OM-09-0009-CPC2","unstructured":"Department of Health.
