However it predisposes patients to nutritional deficiencies and related complications. The aim of this study was to identify nutritional abnormalities, weight loss, adherence to supplements, and presence of gastrointestinal symptoms in a cohort of bariatric surgical patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>An analysis of the electronic medical records of patients attending a multidisciplinary private clinic in Sydney, Australia from August 2020 to August 2021 was conducted. Data on anthropometric measures, nutritional indices, adherence to supplements and gastrointestinal symptoms preoperatively and then at \u22646\u00a0months, 1 and 2\u2009years or more postoperatively were collected.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 231 patients were included in the study. The majority of patients were female (76.2%), with a sleeve gastrectomy (78.8%). Average preoperative BMI was 43.4\u2009\u00b1\u20097.1\u00a0kg\/m<jats:sup>2<\/jats:sup>. Weight loss \u22652\u2009years postsurgery was 33.5\u2009\u00b1\u200912.4\u00a0kg. The most common abnormalities preoperatively were: C\u2010reactive protein (47.7%), vitamin D (39%), B<jats:sub>12<\/jats:sub> (31%), parathyroid hormone (27.6%) and ferritin (12.7%). Vitamin B<jats:sub>12<\/jats:sub> (23.2%), parathyroid hormone (23%), vitamin D (17.7%) and ferritin (15.9%) remained common abnormalities postoperatively.<\/jats:p><jats:p>Adherence to multivitamins was 90% in the first year following surgery, declining to 77% at \u22652\u2009years. Gastrointestinal symptoms were predominantly present in the initial stages following surgery, manifesting thiamin deficiency in 6.5% of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Despite achieving durable weight loss, nutritional and related abnormalities remain an ongoing challenge for bariatric surgery.
