Introdution: In the postoperative period of bariatric surgery, some patients present eating complications such as iron deficiency and iron deficiency anemia.

Objective: To evaluate the nutritional status of iron and iron deficiency anemia in patients undergoing Roux-en-Y gastric bypass or gastric sleeve in a university hospital.

Methods: This was a prospective cohort of 192 patients (135 Roux-en-Y gastric bypass and 57 sleeve) who were followed up at the Outpatient Clinic of Gastroplasty at Hospital das Clínicas of the Federal University of Pernambuco between 2004 and 2016. From Nutritional assessment, data on weight, Body Mass Index, weight loss, hematological profile, serum iron and ferritin were collected after 1, 6 and 12 months of surgery.

Results: Patients were 39.2 ± 9.8 years old, being 82.3% female. After 1 month of surgery, patients submitted to the bypass presented lower levels of iron when compared to the sleeve (61.86 ± 25.25 vs 79.96 ± 22.55, p = 0.007), whichdid not occur after 6 and 12 Months of surgery. There were no differences between the averages of the hematological and Ferritin parameters as a function of the surgical technique. There was no significant correlation between weight loss and hemoglobin, iron and ferritin levels.

Conclusion: No significant differences were found in the hematological profile and in the iron and ferritin levels among obese subjects submitted to bypass or sleeve. When compared to surgical techniques, there were also no significant differences between the prevalence of anemia and iron deficiency
