CHANGES IN NUTRITIONAL PROFILE AFTER 6 MONTHS OF BARIATRIC SURGERY

The aim of this study was to verify, through a densitometric laboratory database, the changes in the nutritional profile of women after 6 months of bariatric surgery. Methods.  A total of 23 Brazilian women aged 40.8±10.4 yrs were included in this study. The sample was recruited at densitometric laboratory database. The analysis was made between 2018 to 2019. Body composition assessments were performed through dual-energy X-ray absorptiometry immediately before and after 6-months Roux-en-Y gastric bypass (RYGB). Data collected pre and post RYGB were included. Food consumption occurred by method of food record, which used data on total caloric intake, macronutrient and micronutrient intake. The collected data was evaluated using the nutritional software WebDiet. Results. Nutritional variables decreased with the exception of the protein and calcium which showed a small increase after surgery following lower calorie intake. Total mass and BMI presented a significant difference, but for the nutritional analysis, despite the important differences between the two stages, they did not present a statistically significant difference. We verified that the Kcal had an important influence in the others nutritional variables in both stages, pre and post surgery, mainly in carbohydrate. Conclusions. We conclude that for this sample there was an important change in eating habits after six months of bariatric surgery and these changes together with bariatric surgery may be the cause of changes and maintenance of weight loss in the patients involved.
