“…The concentration of this protein grows during inflammation, leading to impairment of iron transport from enterocytes to the portal circulation [ 17 ]. Similar observations in a group of patients undergoing bariatric surgery were made – a high percentage of anemia was noted [ 18 ].…”

“…A comparable prevalence (8.7%) of iron deficiency were reported in the studies of Careaga et al and Sánchez et al 3,17 Other studies have reported varying ID prevalence's in patients prior BS and those differences can be explained, in part, by the different criteria applied to define ID. 18,19 According to our logistic regression model, a higher BMI was independently associated with a higher risk of ID. This finding is in agreement with a recent meta-analysis that showed that obesity was associated with ID, although studies with a ferritin-based diagnosis of ID more frequently conclude that obesity is not associated with ID.…”

Introduction: We aim to define the iron deficiency prevalence and eventual differences between obese patients with and without metabolic syndrome. Material and Methods: Analysis of patients evaluated at multidisciplinary consultation of obesity in our institution between 2013 and 2015 (n = 260). Iron deficiency: ferritin levels < 15 ng/mL. Exclusion criteria: prior bariatric surgery; lack of ferritin or hemoglobin determinations. Results: We analyzed data from 215 patients (84.2% female) with a mean age of 42.0 ± 10.3 years. The median body mass index was 42.5 (40.0 -46.8) kg/m 2 and 52.1% had metabolic syndrome. Iron deficiency was present in 7.0%, with no differences between genders or between patients with or without metabolic syndrome. Hypertension was associated with lower prevalence of iron deficiency. Type 2 diabetes and hypertension patients had higher levels of ferritin. The multivariate analysis showed that metabolic syndrome and increasing body mass index were predictive of higher risk of iron deficiency while hypertension predicted lower odds of iron deficiency. Discussion: The prevalence of iron deficiency was similar in other published studies. Iron deficiency may be underdiagnosed if based only on ferritin concentrations. In our study, diabetes and hypertension appear to contribute to the increase in ferritin levels described in obesity. Conclusion: Ferritin may not be a reliable index for evaluating iron stores in obese patients, particularly when associated with comorbidities such as type 2 diabetes and hypertension. Further studies are needed to guide the diagnosis and iron supplementation in these patients.

“…Bariatric surgery, increasingly performed to control caloric intake or diabetes, is emerging as a potential cause of iron deficiency. 15 Post-operative iron deficiency is influenced by preoperative iron status, which is often low in obese patients, and is found more commonly in females. Medical disorders affecting the gastrointestinal tract (eg, rarely autoimmune atrophic gastritis, more frequently Helicobacter pylori gastritis and celiac sprue) impair iron absorption and lead to resistance to oral iron treatment.…”

Iron deficiency and iron deficiency anemia are common conditions worldwide affecting especially children and young women. In developing countries, iron deficiency is caused by poor iron intake and/or parasitic infection, whereas vegetarian dietary choices, poor iron absorption, and chronic blood loss are common causes in high-income countries. Erythropoiesis stimulating agents can result in functional iron deficiency for erythropoiesis even when stores are iron-replete. Diagnosis of iron deficiency is straightforward, except when it occurs in the context of inflammatory disorders. Oral iron salts correct absolute iron deficiency in most patients, because low hepcidin levels facilitate iron absorption. Unfortunately frequent side effects limit oral iron efficacy. Intravenous iron is increasingly utilized, because currently available preparations allow rapid normalization of total body iron even with a single infusion and are effective also in functional iron deficiency and in iron deficiency associated with inflammatory disorders. The evidence is accumulating that these preparations are safe and effective. However, long-term safety issues of high doses of iron need to be further explored. Learning Objectives• To diagnose absolute iron deficiency, iron deficiency anemia, and functional iron deficiency in the light of recent advances in iron metabolism • To evaluate advantages and disadvantages of oral and intravenous iron therapy
