Abstract
ABSTRACT Background : Obesity is one of the main causes of glycemic change. Failure of clinical obesity treatment may lead to an increase in bariatric surgery. Dietary guidance, in conjunction with disabsorptive and hormonal factors resulting from the anatomical and physiological changes provoked by the surgery, is associated with changes in food intake. Aim: To analyze food intake evolution during the first postoperative year of Roux-en-y gastric bypass in patients with type 2 diabetes mellitus or glycemic alteration. Methods : This was a longitudinal and retrospective observational study. For food intake evolution analysis, linear regression models with normal errors were adjusted for each of the nutrients. Results: At 12 months, all patients presented improvement in glycemic levels (p<0.05). During the first postoperative year, there was a reduction in energy intake, macronutrients, consumption of alcoholic beverages and soft drinks. Conversely, there was an increase in fiber intake and diet fractionation. It was observed that, despite gastric restrictions, the micronutrient intake specifically recommended for glycemic control was greater up to six months postoperatively. Conclusion: There was change in the quantity and quality of food intake. It was the most prevalent glycemic control contributor up to six months postoperatively. At the end of one year, the diet underwent a change, showing a similar tendency to the preoperative food intake pattern.
Highlights
Obesity is the major cause of glycemic changes and progression to type 2 diabetes mellitus (DM2)[17]
The inclusion criteria were as follows: adult and elderly patients of both genders, diagnosed with DM2 or fasting hyperglycemia confirmed by preoperative biochemical tests, who underwent Roux-en-y gastric bypass (RYGB) between 2007 and 2014
For alcoholic beverages, Regarding the food intake analysis, this study showed the prevalence was lower, representing 13.2% (n=14) of the that added to the quantitative change, there was a change in sample
Summary
Obesity is the major cause of glycemic changes and progression to type 2 diabetes mellitus (DM2)[17]. It is estimated that 44% of cases are correlated with overweight[27]. The dietary intake profile is directly associated with glycemic improvement. The goal is to maintain glycemic levels within or near normality[21]. Energy and fat reduction, as well as the reduction or exclusion of sugary drink intake and increased fiber consumption, are essential strategies for glycemic improvement[1,3,4]. Intake of fruits and vegetables provides a high amount of micronutrients with potential antioxidant effect, minimizing the damage caused by oxidative and ABCD Arq Bras Cir Dig 2018;31(2):e1367
