PEDROSA, Isabella Valois; BURGOS, Maria Goretti Pessoa de Araújo; SOUZA, Niedja Cristina  and  MORAIS, Caroline Neves de. Nutrition aspects in obese before and after bariatric surgery. Rev. Col. Bras. Cir. [online]. 2009, vol.36, n.4, pp.316-322. ISSN 0100-6991.

OBJECTIVE: To determine the physical-nutritional profile of obese patients submitted to bariatric surgery at the HC/UFPE. MEHTODS: Two-hundred-and-five patients were evaluated retrospectively during the period of 2002 through 2006. Analysis considered clinical history for diabetes type 2 (DM 2), high blood pressure (HBP) and metabolic syndrome (MS). The preoperative nutritional status was evaluated by MBI and the biochemistry (hemoglobin, hematocrit, albumin, total proteins, triglycerides (TG), cholesterol associated with the lipoprotein of high (HDLc) and low (LDLc) density and fasting glycemia (FG). During the postoperative periods (6, 12, 18, 24 months), we evaluated the nutritional status through measures of weight, weight loss, weight loss percentage (%WL), MBI and biochemistry including iron, ferritin, transferrin. RESULTS: Seventy-one and two-tenth percent were female, age was 38.4 ± 9.96 years, and MBI preoperative was 48.6 ± 8.9 Kg /m2. MS diagnosis was present in 26.8%, HBP was present in 52.7% and DM 2 was detected in 11.7%. The biochemistry disclosed TG, it raised LDLc, and FG, and all other parameters were normal. The anthropometrical evolution demonstrated gradual loss, reaching at the 24 months, MBI 31.7±5.82 Kg/m2 (p< 0.001) and greater %WL, 36%. Values of TG, LDLc and FG reached normality at the 6th postoperative month: 104.4mg/dL(p=0.018), 95.5mg/dL(p=0.263) and 84.8g/dL(p=0.004) respectively; the transferrin showed reduced values at the 6th month. A larger prevalence of the symptoms occurred in 6th month: hair loss (19%), vomiting (18%), and food intolerances (12.2%). CONLCUSION: The bariatric surgery was an efficient procedure to promote weight loss and its maintenance in two years, as well as improvement of biochemical parameters and comorbidities, with reduced clinical-nutritional symptoms and/or prevented by nutritional monitoring.
