BACKGROUND: Abdominoplasty, the treatment for abdominal wall deformity stemming from weight loss after bariatric surgery, can cause postoperative anemia. Moreover, bariatric surgery has been associated with iron deficiency, which by itself can compromise erythropoiesis. The objective of this research is to describe the development of anemia after postbariatric abdominoplasty. METHODS: The study group consisted of 32 adult women who had received bariatric surgery. Treatment group included 20 patients who were undergoing postbariatric abdominoplasty. Control group included 12 patients waiting for abdominoplasty. Values of hemoglobin, reticulocytes, iron, ferritin, and the transferrin saturation were obtained on the evening before abdominoplasty and during the first, fourth, and eighth postoperative weeks. Hemoglobin was measured at 48 h. RESULTS: Mean hemoglobin levels for treatment group decreased from 12.98 to 10.8 g/dL after 48 h, increased on day 7 to 11.53 g/dL, but did not increase further after day 7. The reticulocyte number increased in the first week. Serum iron and transferrin saturation index fell during the first week and remained low. Ferritin levels increased non-significantly from 29.77 to 37.24 ng/mL at week 1, then fell until they were decreased (16.44 ng/mL) by day 56. CONCLUSIONS: As expected, hemoglobin fell after abdominoplasty. However, after a one-third recovery of hemoglobin concentrations by week 1 postoperative, they failed to return to preoperative levels by the eighth week. Additionally, by the eighth postoperative week, 45 % of abdominoplasty patients had developed an iron deficiency and hemoglobin deficit that was higher than that of patients who maintained normal iron stocks.
