Hence, clinical attention to women with history of bariatric surgery and a normal weight status in early pregnancy might be warranted,” the authors advised.</p> <h2>SOURCE:</h2> <p>The study, with the first author Huiling Xu, MD, MSc, Karolinska Institutet, Stockholm, Sweden, was <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2812561?utm_source=For_The_Media&amp;utm_medium=referral&amp;utm_campaign=ftm_links&amp;utm_term=120523">published online</a> in JAMA Network Open.</p> <h2>LIMITATIONS:</h2> <p>Despite rigorous matching, residual confounding was possible. The sample size was limited for some subgroups, possibly affecting statistical power. Although the study provides an overview of pregnancy outcomes within surgery-to-conception interval and pregnancy weight gain z scores, a more in-depth investigation is needed to understand the associations among bariatric surgery, pregnancy weight gain, and pregnancy outcomes.</p> <h2>DISCLOSURES:</h2> <p>Research for this study was supported by the Swedish Research Council for Health, Working Life and Welfare, and the Swedish Research Council.
