Introduction: Bariatric surgery predisposes patients to nutritional deficiencies. There are limited studies on zinc and copper abnormalities in this cohort. Purpose: The aim of this study was to identify the prevalence of these abnormalities in a cohort of Australian bariatric patients. Inflammatory markers, adherence to multivitamin supplementation (MVS) and the presence of gastrointestinal (GI) symptoms were also investigated. Material and Methods: Data was collected on all patients who attended a single clinic in Sydney, Australia, from August 2020 to August 2021. Results: The study cohort consisted of 231 patients (76.2% female; mean pre-operative body mass index of 43.4 ± 7.1 kg/m2), most of whom underwent sleeve gastrectomy (78.8%). Data were collected preoperatively and then at ≤ 6 months, 1 and > 2 years postoperatively. Prior to surgery, low levels of zinc (2.1%) and copper (0.7%) were rare, but elevated copper levels were common (16.7%) and potentially related to an ele
