“…Nas técnicas restritivas (balão intragástrico, Banda Gástrica Ajustável -BGA e Gastroplastia Vertical com Bandagem -GVB, também conhecida como cirurgia de Mason) ocorre restrição do conteúdo gástrico, provocando saciedade precoce com pequena quantidade de alimentos ingerida. Já as técnicas consideradas mistas (derivação gástrica em Y-de-Roux, cirurgia de Scopinaro/Derivação Biliopancreática -DBP com gastrectomia distal e Derivação Biliopancreática com gastrectomia vertical e preservação do piloro -DBP/DS) apresentam uma parcela restritiva e evitam ou diminuem a absorção de nutrientes por meio de uma derivação no intestino delgado, diminuindo sua área absortiva 12,32,33 .…”

This article discusses vitamin B12 deficiency and its reflexes in the health of people undergoing bariatric surgery. This is an exploratory descriptive study of the type literature review in which a search was conducted for articles from journals indexed in the Pubmed/MEDLINE and Scielo databases, using the descriptors bariatric surgery, obesity, postoperative care, malnutrition and vitamin B12 in order to gather information about this deficiency and its reflexes on the health of this population. The inclusion criteria were work on the theme from 2005 to 2016. With this, 35 articles were selected. The findings confirmed the existence of malnutrition of vitamin B12 in people who underwent this type of surgery and explained the importance of its longterm supplementation for its prevention and/or treatment, and although there are no specific recommendations for this population yet, it has been a preventive clinical practice to administer 1000 μg parenteral in the preoperative period and in the postoperative period may be oral (2000 mcg/120 days) or intramuscular (1000 mcg injections). Therefore, this deficiency in bariatric patients is evidenced in the current literature that elucidates their health reflexes, demonstrating the importance of their supplementation before and after surgery, but there is a need for more specific studies that help in the creation of precise protocols.

“…In the postoperative period of bariatric surgery, we previously observed a change in the pattern of food intake through a significant reduction in energy intake and that of micro and macronutrients 18 . Additionally, bariatric surgery has been associated with behavioral changes related to food preference and choice, as well as increasing dietary fractionation 12 .…”

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.

“…A vitamina B12 é também chamada de cianocobalamina por conter o microelemento cobalto ligado a um grupo cianeto em sua estrutura. É uma vitamina hidrossolúvel sintetizada exclusivamente por bactérias, sendo encontrada também nos tecidos animais que a adquirem indiretamente pelo consumo desses microrganismos e por esta razão, não é encontrada em fontes vegetais (Rocha, 2012;Vannucchi & Monteiro, 2010).…”

“…A deficiência de B12 pode ser causada pela ingestão deficiente de proteína e cobalamina, má digestão de B12 com proteína ligada, secreção insuficiente do fator intrínseco (FI) e má absorção do complexo B12+FI. Pelo fato da cianocobalamina estar envolvida na maturação de células vermelhas e em importantes funções metabólicas e neurotróficas, sua deficiência pode resultar em anemia macrocítica, neuropatia periférica e sintomas psiquiátricos (Rocha, 2012). O folato, ou vitamina B9, faz parte das vitaminas do complexo B, sendo hidrossolúvel.…”

In aging, some level of functional impairment is common as a consequence of health problems inherent to this phase of life. The literature demonstrates the importance of micronutrients for prevention or control of these diseases. In this context, vitamin B12 and folic acid (B9) are noteworthy, as their deficiency is associated with complications that may decrease the quality of life of this population. Therefore, the aim of the present study was to perform a review to describe important aspects related to the association between B12 and B9 in the cognitive health of the elderly. A total of 16 articles were used to compose the review, divided into 3 analysis categories that relate these micronutrients to the occurrence of Alzheimer's disease, loss of cognition and the presence of depression in the elderly. Low levels of B12 and B9 have been observed in Alzheimer's disease. Most articles related reduced vitamin levels with poor performance on cognitive performance, and finally, low concentrations of micronutrients were found in elderly with depression. Based on the above, it can be inferred that B12 and B9 deficiency is associated with increased homocysteine and methylmalonic acid concentrations that cause central nervous system alterations, especially resulting in depression and cognitive impairment, making it important to routinely evaluate the levels of these vitamins. in the elderly as they constitute a group of high vulnerability.
