“…These values differ considerably from those reported by other authors [11,12,35,36,38,39] (Table 5). Such differences may be attributable to poor dietary habits in the general population, socioeconomic factors, gastrointestinal pathologies, and/or the use of different cutoff points for defining nutritional deficiency.…”

“…However, such procedure carries the risk of complications, such as deficiencies for micronutrients, even when supplements are used [13,[28][29][30][31][32]. Moreover, obese patient often present with micronutrient deficiencies before to bariatric surgery [9][10][11][12][13][33][34][35][36][37][38][39][40].…”

“…Data regarding nutritional indicators for obese patients seeking bariatric surgery are scarce; however, some authors have noted low pre-surgical plasma concentrations of iron, hemoglobin, ferritin, zinc, folic acid, vitamin B 12 , 25(OH)D, calcium, among others. (Table 5) [9][10][11][12][13][33][34][35][36][37][38][39][40].…”

Background: Bariatric surgery is an alternative treatment for obesity. However, physicians need to be aware of the possible consequences of nutritional deficiencies with this type of surgery. This study aimed to determine the prevalence of inadequacy of macro-and micronutrients from the diet in patients undergoing Roux-en-Y gastric bypass after 3, 6, and 12 months postoperatively. Methods: We performed a longitudinal, observational, clinical study during preoperatively and 3-, 6-, and 12-month postoperatively (n = 95 patients). We collected information from medical records of patients in a Reference Clinic of Bariatric Surgery. Quantitative food intake was analyzed by ADS Nutri ® and Multiple Source Method ® software. The obtained data were compared with the daily-recommended intake in accordance with specific guidelines for bariatric surgery. Data were analyzed using t-tests, MannWhitney test, one-way analysis of variance (ANOVA), and Tukey's test. Results: There was a high prevalence of inadequacy of macronutrients and micronutrients from food in the postoperatively period. However, only vitamin B12 intake was adequate based on the daily recommended intake. Conclusions: Our study suggests that the intake of nutrients by feeding is below current recommendations. Individual nutritional counseling with a therapeutic plan for adequate nutrition and prescription supplements are important to ensure that nutritional recommendations are adhered to.

“…Up to half [9][10][11][12][13] of bariatric surgery patients are deficient in Zn preoperatively and RYGB can further exacerbate it [4,9,12] through probably both reduced intake [15][16][17][18] and reduced absorption [15,19] as Zn is predominantly absorbed in the duodenum and the proximal jejunum.…”

Zinc Deficiency after Gastric Bypass for Morbid Obesity: a Systematic Review

Usage guidelinesPlease refer to the usage guidelines at http://sure.sunderland.ac.uk/policies.html or alternatively contact sure@sunderland.ac.uk. 1 Abstract:Up to 50 % of patients have Zinc deficiency before bariatric surgery. Roux-en-Y Gastric Bypass (RYGB) is the commonest bariatric procedure worldwide. It can further exacerbate Zinc deficiency by reducing intake as well as absorption. British Obesity and Metabolic Surgery Society, therefore, recommends that Zinc level should be monitored routinely following gastric bypass. However, the American guidance does not recommend such monitoring for all RYGB patients and reserves it for T Z after RYGB. Routine monitoring of Zinc levels is hence unnecessary for asymptomatic patients after RYGB and should be reserved for patients with skin lesions, hair loss, pica, dysgeusia, hypogonadism or erectile dysfunction in male patients, and unexplained iron deficiency anaemia.
