“…Tables 1 and 2 provide an overview of the studies to date that have evaluated iron intake after RYGB and SG. After surgery, iron intake was mostly lower or even inadequate compared with the available estimated average requirements or dietary reference intake for healthy individuals (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) . Postoperatively, the restricted dietary intake, increased satiety and reduced appetite contribute to the lower iron intake by means of a reduced intake of micronutrients (27) .…”

Iron deficiency after bariatric surgery: what is the real problem?

The growing prevalence of obesity explains the rising interest in bariatric surgery. Compared with non-surgical treatment options, bariatric surgery results in greater and sustained improvements in weight loss, obesity associated complications, all-cause mortality and quality of life. These encouraging metabolic and weight effects come with a downside, namely the risk of nutritional deficiencies. Particularly striking is the risk to develop iron deficiency. Postoperatively, the prevalence of iron deficiency varies between 18 and 53 % after Roux-en-Y gastric bypass and between 1 and 54 % after sleeve gastrectomy. Therefore, preventive strategies and effective treatment options for iron deficiency are crucial to successfully manage the iron status of patients after bariatric surgery. With this review, we discuss the risks and the contributing factors of developing iron deficiency after bariatric surgery. Furthermore, we highlight the discrepancy in the diagnosis of iron deficiency, iron deficiency anaemia and anaemia and highlight the evidence supporting the current nutritional recommendations in the field of bariatric research. In conclusion, we advocate for more nutrition-related research in patient populations in order to provide strong evidence-based guidelines after bariatric surgery.

“…The mechanism for zinc deficiency depends on the surgical procedure and time lapsed after surgery. Intolerance to food containing zinc 94 and, thus, decreased dietary intake of zinc, 95 increase the risk of zinc deficiency. Hydrochloric acid is required for zinc absorption and is reduced by some of these procedures 96 .…”

Nutrition and Metabolic Support Recommendations for the Bariatric Patient

et al. 2014

Managing the metabolic needs of the patient with obesity is a challenge unto itself without the added demands of accounting for an altered gastrointestinal tract. Nevertheless, with about 200,000 bariatric procedures being performed annually in the United States, clinicians must be prepared to manage the critically ill bariatric surgery patient. This article reviews the recent literature relating to nutrient needs and metabolic support for the bariatric patient. Bariatric patients are at risk for several micronutrient deficiencies, including vitamins D and B₁₂, calcium, and iron; some bariatric procedures affect macronutrient needs as well. Literature on nutrition support guidelines for the bariatric population is limited. However, with an understanding of the anatomical and physiological effects of bariatric surgery, recent guidelines for critically ill patients with obesity can be applied to the bariatric surgery population. The unique needs of the bariatric population, such as susceptibility to micronutrient deficiencies and specialized access routes, must be considered to provide safe and efficacious nutrition support. Further research is necessary to develop specific nutrition support recommendations for the bariatric population.

“…Because iron is poorly absorbed after surgery, the impact of iron obtained from the diet is uncertain. After RYGB, dietary intake of iron is lower than recommended amounts [12][13][14]. The bypass procedure promotes early satiety so that food intake is decreased [12].…”
