Nutritional Aspects and the Use of Nutritional Supplements by Women Who Underwent Gastric Bypass

Abstract

Background:Bariatric surgery is deemed one of the most effective procedures for the treatment of obesity and it aims at the reduction and maintenance of weight loss in long term, as the control of the related comorbidities. Aim: Quantify the occurrence of alterations of the gastrointestinal tract, suggestive signs of nutritional deficiencies and the use of supplements in a group of women undergoing bariatric surgery. Methods: The sample consisted of women aged 20-65 years submitted to Roux-en-Y gastric bypass with monitoring equal to or higher than 24 months. For the qualitative analysis, the Feeding Frequency Questionnaire was used. Results: In the postoperative period, alopecia was the most reported (79.3%), followed by changes in the texture of the nails, both considered predictive of nutritional deficiencies. Changes in the gastrointestinal tract were described in 86.2%, and episodes of dumping were reported in 65.5%. Qualitative analysis has shown reduced daily consumption of sources of animal and plant proteins. Conclusion: After bariatric surgery can occur flatulence, vomiting and dumping syndrome as the most frequent representative symptoms of digestive functional disorders. Alopecia and nail changes are the most important signs of nutritional deficiency. The use of dietary supplements in the postoperative period is scarce and sporadic.

Is There Any Change in Phenotypic Characteristics Comparing 5 to 10 Years of Follow-Up in Obese Patients Undergoing Roux-en-Y Gastric Bypass?

“…Despite the favorable results associated with bariatric surgery, nutritional deficiencies, due to changes in dietary intake, as well as reduction of gastric capacity and intestinal absorption surface, are very common 10 , 39 . Thus, micronutrient supplementation is recommended to prevent post-surgical deficiencies 10 , 38 . In addition, several long-term studies have identified recovery of weight lost in a portion of patients submitted to the surgery, which can be attributed to the presence of eating disorders, dilation of the gastric pouch, physical inactivity, endocrine and metabolic changes 2 , 8 , 17 , 21 , 28 .…”

Hair Loss After Metabolic and Bariatric Surgery: a Systematic Review and Meta-analysis

“…A study with an NOS score of 7–9 points was defined as high quality. The methodological quality of the cross-sectional studies [ 14 , 16 , 21 – 23 ] included was assessed using an 11-item checklist recommended by Agency for Healthcare Research and Quality (AHRQ) [ 27 ]. An item would be scored “0” if it was answered “NO” or “UNCLEAR”; if it was answered “YES,” then the item scored “1.” Article quality was assessed as follows: low quality = 0–3; moderate quality = 4–7; high quality = 8–11.…”

Perfil Alimentar E Reganho De Peso De Pacientes Submetidos À Cirurgia Bariátrica Em Um Hospital Universitário / Food Profile and Weight Regain of Patients Submitted to Bariatric Surgery in an University Hospital

“…No presente estudo, mais da metade dos indivíduos tiveram ingestão alimentar inadequada de cálcio, ferro e vitamina D. Além disso, 23,3% da amostra não realizou a suplementação de vitaminas e minerais. Já no estudo realizado porTrindade et al (2017), identificou-se que 69% da sua amostra descontinuaram o uso de suplementos vitamínico e minerais. Para analisar se esses resultados surtiram efeitos sobre os níveis séricos desses nutrientes, seria necessária a análise dos exames bioquímicos, que não foram avaliados no presente estudo.Quanto à avaliação qualitativa através de escores, não foram encontrados trabalhos semelhantes abordando pacientes no pós-operatório de bariátrica para comparação dos resultados.…”
