It is estimated that the prevalence of anaemia in patients scheduled for bariatric surgery is higher than in the general population and the prevalence of iron deficiencies (with or without anaemia) may be higher as well. After surgery, iron deficiencies and anaemia may occur in a higher percentage of patients, mainly as a consequence of nutrient deficiencies. In addition, perioperative anaemia has been related with increased postoperative morbidity and mortality and poorer quality of life after bariatric surgery. The treatment of perioperative anaemia and nutrient deficiencies has been shown to improve patients' outcomes and quality of life. All patients should undergo an appropriate nutritional evaluation, including selective micronutrient measurements (e.g., iron), before any bariatric surgical procedure. In comparison with purely restrictive procedures, more extensive perioperative nutritional evaluations are required for malabsorptive procedures due to their nutritional consequences. The aim of this study was to review the current knowledge of nutritional deficits in obese patients and those that commonly appear after bariatric surgery, specifically iron deficiencies and their consequences. As a result, some recommendations for screening and supplementation are presented.
据估计，计划接受减重手术的患者的贫血患病率高于一般人群，铁缺乏症（无论是否贫血）的患病率也可能更高。手术后，铁缺乏症和贫血可能在更高比例的患者中发生，主要是由于营养缺乏。此外，围手术期贫血与术后发病率和死亡率增加以及减重手术后生活质量下降有关。围手术期贫血和营养缺乏的治疗已被证明可以改善患者的预后和生活质量。所有患者都应在进行任何减重手术前接受适当的营养评估，包括选择性微量营养素测量（例如铁）。与纯粹的限制程序相比，由于吸收不良程序的营养后果，更广泛的围手术期营养评估是必需的。本研究旨在回顾肥胖患者和减重手术后常见的营养不足的现有知识，特别是铁缺乏症及其后果。因此，提出了一些筛查和补充的建议。
