Food Intake Evaluation During the First Year of Postoperative of Patients With Type 2 Diabetes Mellitus or Glycemic Alteration Submitted to Roux-en-Y Gastric Bypass

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.

The Role of Dietary Intake in the Weight Loss Outcomes of Roux-en-Y Gastric Bypass and Sleeve Gastrectomy: A Systematic Review and Meta-analysis

“…Various dietary assessment methods were employed across different studies. Nineteen (46%) studies utilized a food recall [13,16,[18][19][20][21][22][23][24][25][26][27][28][29][30], and seventeen (41%) used dietary records [14,28,[31][32][33][34][35][36][37][38][39][40], while the remaining studies used food frequency questionnaires (n = 8; 20%) [17,[41][42][43][44][45] or employed mixed methods (n = 5; 12%) [15,17,41,45,46]. The best method regarding flexibility, accuracy, and reflection of the actual diet is a dietary diary.…”

“…Daily energy (kcals) was reported in 90% of studies (n = 37) [8,[48][49][50][51][52]; all studies reported macronutrient intake whereas only ten studies (24%) [14,19,21,26,30,33,35,38,43,45] reported micronutrient intake.…”

“…Only ten studies investigated the micronutrient intake following RYGB and/or SG [14,19,21,26,30,33,35,38,43,45]. As summarized in Table 2, in the short term (≤ 12 months), vitamin B12 intakes met the UK RDA of 2.4 µg/ day in all the studies while zinc intake was < 8 mg/day in two studies [33,35] at 3-and 12-month post-surgery. Dias et al reported iron intake < 8 mg/day at 3-and 12-month post-surgery [33].…”

“…Além disso, o abuso de alimentos e de bebidas alcoólicas no período pós-cirúrgico também é algo muito comum e responsável por resultados pouco efetivos (Zaparolli et al, 2018). Corroborando com a pesquisa de Lupoli et al (2017) que declara que existe a questão crítica através do ganho de peso pós-operatório, pelo descuido do paciente.…”
