“…Similarly, low levels of vitamin B1 (thiamine) are reported in up to 20% of bariatric candidates. Few studies have assessed the vitamin C status in bariatric candidates, with a prevalence that ranges from 15%[ 69 ] to 33%[ 79 ]. With regard to vitamins A and E, their deficiencies are less frequent[ 69 , 73 ].…”

Bariatric surgery is recognized as a highly effective therapy for obesity since it accomplishes sustained weight loss, reduction of obesity-related comorbidities and mortality, and improvement of quality of life. Overall, bariatric surgery is associated with a 42% reduction of the cardiovascular risk and 30% reduction of all-cause mortality. This review focuses on some nutritional consequences that can occur in bariatric patients that could potentially hinder the clinical benefits of this therapeutic option. All bariatric procedures, to variable degrees, alter the anatomy and physiology of the gastrointestinal tract; this alteration makes these patients more susceptible to developing nutritional complications, namely, deficiencies of macro- and micro-nutrients, which could lead to disabling diseases such as anemia, osteoporosis, protein malnutrition. Of note is the evidence that most obese patients present a number of nutritional deficits already prior to surgery, the most important being vitamin D and iron deficiencies. This finding prompts the need for a complete nutritional assessment and, eventually, an adequate correction of pre-existing deficits before surgery. Another critical issue that follows bariatric surgery is post-operative weight regain, which is commonly associated with the relapse of obesity-related co-morbidities. Nu-tritional complications associated with bariatric surgery can be prevented by life-long nutritional monitoring with the administration of multi-vitamins and mineral supplements according to the patient’s needs.

“…Vitamin C, or ascorbic acid, is required for proper collagen synthesis. Pre–bariatric surgery deficiency has been reported in up to 43% of obese patients; however, most reports suggest deficiency after bariatric surgery is rare 18 , 54 , 55 . When present, vitamin C deficiency leads to scurvy, which manifests with petechiae, hyperkeratosis, gingivitis, ecchymoses, and/or perifollicular bleeding 56 , 57 .…”

Micronutrient Deficiencies After Bariatric Surgery: An Emphasis on Vitamins and Trace Minerals

Obesity has become a worldwide epidemic with a disproportionate increase in grade III obesity. Bariatric surgery offers an attractive option for sustained weight loss compared with traditional methods such as exercise and diet. Micronutrient deficiencies are common and clinically significant after bariatric surgery. These deficiencies are related to a combination of patient and surgical variables. A thorough understanding of specific micronutrient deficiencies is necessary for early recognition and optimal management. The purpose of this review is to describe indications, outcomes, and types of bariatric procedures, risk factors, and mechanisms for micronutrient deficiencies, as well as outline specific vitamin and trace element deficiencies after bariatric surgery.

“…A alta prevalência de desnutrição em indivíduos com excesso de peso e obesidade é demonstrada na literatura científica (KAIDAR-PERSON et al, 2008;WOLF et al, 2015). A insuficiência múltipla de vitaminas e minerais descrita acima também acomete candidatos à cirurgia bariátrica, visto que em sua maioria possuem obesidade mórbida (KRZIZEK et al, 2017;LIMA et al, 2013;WOLF et al, 2015). Há concordância científica de que a avaliação do estado pré-operatório é primordial para auxiliar na suplementação antes e após a cirurgia bariátrica e evitar maiores complicações no período pósoperatório (ROUST; DIBAISE, 2017;WOLF et al, 2015).…”

A obesidade é uma doença crônica e tem se tornado uma epidemia em todo o mundo. Sua etiologia é multifatorial e o tratamento complexo, envolvendo dieta, exercícios físicos, fármacos e, em casos mais graves, cirurgia. De acordo com os guias e consensos, nacionais e internacionais, a distribuição dos macronutrientes fica em torno de 35% a 65% do valor energético total (VET) de carboidratos, 15 a 25% do VET de proteínas e 20 a 40% do VET de lipídios. Por meio de uma revisão de literatura, foram encontradas recomendações controversas. Conforme análise crítica dos pesquisadores envolvidos e de acordo com resultados de pesquisas recentes, concluiu-se que dieta hipocalórica (restrição de 500 a 750 kcal/dia), hiperproteica (>25% do VET), hipoglicídica e normolipídica foi eficaz na perda e manutenção do peso a longo prazo. Em relação aos lipídios, verificou-se que a dieta deve ser mais qualitativa, com a redução na ingestão de colesterol, gorduras saturadas e trans. O consumo de fibras deve ser estimulado. Dietas restritivas não se mostraram sustentáveis por um longo período, mas podem ser usadas em um período determinado. Além disso, a alta prevalência de deficiência de micronutrientes em indivíduos com obesidade foi consensual entre os autores, inclusive antes da cirurgia bariátrica. Concluiu-se que a adesão dietética e, consequentemente, o balanço negativo são fatores decisivos para a promoção da perda de peso. O planejamento alimentar deve ser flexível e individualizado e o contato entre o nutricionista e o paciente deve ser constante, visando a reeducação alimentar. O presente artigo realizou uma análise crítica das recomendações de macro e micronutrientes na obesidade visando contribuir para o tratamento dietético dessa população.
