“…In the present study, the significant reduction in energy intake was accompanied with a reduced intake of folate, vitamin B12, vitamin D and iron. In general, reported dietary micronutrient intake was already low before surgery and worsened post‐surgery, which is in accordance with previous research 16,26 . Nonetheless, it is not realistic to expect micronutrient intake from diet alone to provide the required levels needed to prevent micronutrient deficiencies after BS.…”

“…In general, reported dietary micronutrient intake was already low before surgery and worsened post-surgery, which is in accordance with previous research. 16,26 Nonetheless, it is not realistic to expect micronutrient intake from diet alone to provide the required levels needed to prevent micronutrient deficiencies after BS. To illustrate, intake of iron at 6 months post-surgery was 7.1 ± 2.3 mg, whereas daily iron requirements are estimated to be 45-60 mg after BS.…”

BackgroundBariatric surgery (BS) may result in inadequate nutrient intake and poor diet quality, which can lead to nutritional complications. The present study aimed to evaluate changes in macro‐ and micronutrient composition and diet quality in the first 6 months following BS.MethodsOne hundred seven participants undergoing BS (Roux‐en‐Y gastric bypass: n = 87, sleeve gastrectomy: n = 20) completed 3‐day food records before and 6 months after surgery. Changes in energy, macronutrient (carbohydrates, protein, fat, dietary fibre) and micronutrient intake (folate, vitamin B12, vitamin D, calcium, iron) were evaluated. Diet quality was assessed by adherence to the Dutch food‐based dietary guidelines.ResultsAfter BS, we observed a significant decrease in intake of energy and all macro‐ and micronutrients (p < 0.01 for all), except for calcium (−39.0 ± 404.6 mg; p = 0.32). Overall, nutrient composition slightly changed with an increase in the relative intake of protein (+1.1 ± 4.3 energy percentage [en%]; p = 0.01) and mono‐ and disaccharides (+4.2 ± 6.4 en%; p < 0.001) post‐surgery. Consumption (median [Q1, Q3]) of vegetables (−50 [−120, 6] g day–1), wholegrain products (−38 [−81, −8] g day–1), liquid fats (−5 [−13, 2] g day–1), red meat (−3 [−30, 4] g day–1), processed meat (−32 [−55, 13] g day–1), sodium (−0.7 [−1.1, −0.2] g day–1) and unhealthy food choices (−2.4 [−5.0, 0.6] serves week–1) significantly decreased after BS (p < 0.01 for all).ConclusionsOur results demonstrate both favourable and unfavourable changes in macro‐ and micronutrient composition and diet quality in the first 6 months following BS. Insight into these changes can improve dietary counselling in this population. Future research into underlying causes, consequences and long‐term changes in dietary intake is needed.

Purpose: Bariatric surgery induces nutritional deficiencies that require long-term monitoring and supplementation. This study aimed to evaluate the status of vitamins and minerals pre-operation and 2 years post-operation and to compare the findings according to type of bariatric surgery. Methods: The study enrolled 302 patients who underwent bariatric surgery, adjustable gastric band (AGB), sleeve gastrectomy (SG), or Roux-en-Y gastric bypass (RYGB) between 2013 and 2017 in the CHA Gangnam Medical Center and the Seoul Medical Center, Korea. Minerals and vitamin status was assessed at baseline (pre-operatively) until 2 years after bariatric surgery. Results: Mean age was 34.1±8.3 years, 256 patients (84.8%) were female, and mean body mass index was 35.3±5.7 kg/m 2 . Vitamin B1, vitamin B12, and folic acid levels were significantly different at 1 and 2 years after surgery compared to baseline. Hemoglobin, hematocrit, high-density lipoprotein, iron, calcium, and magnesium levels did not differ significantly during the study period. Conclusion:Although enrolled patients had no clinical symptoms of nutritional deficiences, several indicators related to nutrition decreased at 2 years after bariatric surgery. Despite variations in the alteration of laboratory results across three surgical interventions, namely SG, AGB, and RYGB, a consistent reduction in fasting blood sugar was observed subsequent to the surgical procedures.
