Abstract in Portuguese
Objetivo. Realizar avaliação nutricional de pacientes com obesidade mórbida, antes e após a cirurgia, para avaliar mudanças no estado nutricional e de prática alimentar após cirurgia bariátrica. Métodos. Foram realizadas anamnese alimentar e clínica, avaliação da ingestão alimentar atual pelo diário alimentar de 3 dias; avaliação antropométrica como peso, altura para obtenção do Índice de massa corpórea (IMC) e bioimpedância elétrica (BIA); e exames bioquímicas indicativos do estado nutricional. A coleta de dados foi realizada antes e após 5,7 meses de realizada a cirurgia. Resultados. A amostra foi composta de 18 adultos, idade média de 38,33 ± 12,07 anos, sendo 77,8% mulheres. Antes da cirurgia o IMC médio era de 47,57±5,6 kg/m2, com 51,41±11,7% de porcentagem de gordura corpórea (%GC). Após a cirurgia o IMC médio diminuiu para 37,09±5,09 kg/m2 e a %GC para 42,71±11, 10%. Antes da cirurgia o valor calórico total (VCT) médio da dieta foi de 2038,06 ± 820,89 kcal, com distribuição de macronutrientes dentro das recomendações. Após a cirurgia VCT diminuiu para 944,45 ± 365,49 kcal, sem alteração na distribuição de macronutrientes. Não houve alteração no padrão alimentar antes e após a cirurgia, e também nas preferências e.aversões alimentares. Com relação às co-morbidades, houve diminuição significativa da presença de Hipertensão Arterial. Quanto aos exames bioquímicas houve diminuição significativa do hematócrito, hemoglobina, proteína total, ácido úrico, triglicérides, colesterol total, glicemia, e aumento de sódio, porém dentro dos parâmetros da normalidade. Conclusões. Houve melhora do estado nutricional após a cirurgia, pois mesmo com uma grande perda de peso não houve desnutrição; porém, os pacientes não alteraram a prática alimentar.

Abstract in English
Objective. Realize nutritional assessment before and after bariatric surgery to evaluate changes in nutritional status and food pattern after bariatric surgery. Methods. The participants realized dietetic and clinical questionnaires before and after surgery. The actual food intake was analyzed by a three days food diary, antropometry (weight and height), body mass index (BMI) and bioelectrical impedance (BIA) and biochemical parameters of nutritional status. Data collection was realized before and after 5.7 months surgery had been done. Results. The sample was composed of 18 adults, mean of age 38.3 ± 12.07 years old, and .77.8% of women. Before surgery the mean of BMI was 47.57 ± 5.6 kg/m2 , with 51.41 ± 11.7% percentage of body fat. After surgery the mean BMI decreased to 37.09 ± 5.09 kg/m2 and the percentage of body fat to 42.71 ± 11.10%. Before surgery the mean of total energy intake was 2038.06 ± 820.89 kcal, and macronutrients distribution was in accordance to DRis. After surgery total energy intake decreased to 944.45 ± 365.49 kcal, without changes in the macronutrients distribution. There were no significant differences in the food pattern before and after surgery, as well in food preferences. In relation of co - morbidities, a significant decreased of HAS was observed. About the biochemicals markers, there were a significant decreased in hematocrit, hemoglobin, total protein, uric acid, triglycerides, total cholesterol, fasting plasma glucose, and increased of sodium, although all of them were in the normal range. Conclusions. Nutritional status improved after surgery, since there was a significant weight and body fat loss, and there was no malnutrition. However, patients had not changed food pattern.
