“…According to Papamargaritis et al, serum levels of zinc, copper, and selenium were found to be relatively stable after both RYGB and VSG in supplemented patients, although a likelihood for selenium serum levels to decrease was observed [168]. Selenium deficiency was not documented by Pellitero et al in VSG patients following surgery [166].…”

Bariatric Surgery in Obesity: Effects on Gut Microbiota and Micronutrient Status

et al. 2020

Obesity is associated with reduced gut microbial diversity and a high rate of micronutrient deficiency. Bariatric surgery, the therapy of choice for severe obesity, produces sustained weight loss and improvements in obesity-related comorbidities. Also, it significantly alters the gut microbiota (GM) composition and function, which might have an important impact on the micronutrient status as GM is able to synthesize certain vitamins, such as riboflavin, folate, B12, or vitamin K2. However, recent data have reported that GM is not fully restored after bariatric surgery; therefore, manipulation of GM through probiotics represents a promising therapeutic approach in bariatric patients. In this review, we discuss the latest evidence concerning the relationship between obesity, GM and micronutrients, the impact of bariatric surgery on GM in relation with micronutrients equilibrium, and the importance of the probiotics’ supplementation in obese patients submitted to surgical treatment.

“…Pellitero et al reported that 23% of patients had anemia, 16.5% of folic acid deficiency, 6.9% of vitamin B12 deficiency and 73% of vitamin D deficiency after LSG operation (19). The authors found that nutritional deficiencies were usually evident within the first two years after surgery and improved during the five-year followup duration.…”

Aim: The aim of this study was to evaluate the changes in vitamin B12, ferritin, folic acid, and thyroid hormone levels in patients with morbid obesity after laparoscopic sleeve gastrectomy (LSG). Material and Methods: A total of 85 patients who underwent LSG operation with the diagnosis of morbid obesity were included in the study. Levels of vitamin B12, ferritin, folic acid, and thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4) hormone were measured using the chemiluminescence method. Pre-and postoperative levels of thyroid hormones, vitamin B12, ferritin, folic acid, and BMI values were evaluated. Results: The mean BMI decreased from 45.44 ± 3.8 kg/m2 to 39.38 ± 3.69 kg/m2 (p<0.001). The mean TSH, fT3, vitamin B12, folic acid, and ferritin levels were statistically significant lower at six months postoperatively than preoperative levels, while the mean fT4 levels were found to be significantly higher (p<0.001). Preoperative and 6thmonth postoperative ferritin levels were significantly lower in female patients than male patients (p<0.001). There was a negative correlation between age with preoperative TSH and fT3 levels. There was a positive correlation between age and preoperative and 6thmonth postoperative folic acid levels. Conclusion: Remodeling of the gastrointestinal system and endocrine alterations after LSG may result in changes in the levels of nutritional parameters such as thyroid hormone, vitamin B12, folic acid, and ferritin. Therefore, based on our study findings, we consider that the nutritional status of patients after bariatric surgery should be monitored particularly in long-term and nutritionally supported, if necessary.

“…Bariatric surgeries increase the risk of thiamin deficiency through several mechanisms, including lower vitamin intake, higher prevalence of postoperative vomiting, and impaired absorption, mainly in patients who have undergone Roux‐en‐Y gastric bypass surgery. In these patients, the bypass of the small intestine, the preferred location for thiamin absorption, and bacterial overgrowth are important causes of thiamin deficiency . In addition, obesity alone can increase risk of thiamin deficiency.…”

Role of Thiamin in Health and Disease

Thiamin is a hydrosoluble vitamin that plays a role in several biological processes, mainly in glucose metabolism. There are several risk factors for developing thiamin deficiency, such as malnutrition, refeeding syndrome, gastrointestinal surgery, and alcoholism. Recently, the role of thiamin in critically ill patients has gained prominence, and the prevalence of thiamin deficiency was found to be increased in patients with severe burns, major surgery, septic shock, end-stage renal disease, and heart failure. In adults, thiamin deficiency presents as encephalopathy, dry beriberi (with neurological signs and symptoms), or wet beriberi (with cardiovascular signs and symptoms). Thiamin deficiency can be diagnosed clinically, and all clinicians should be aware of this disease, especially in patients with risk factors for thiamin deficiency. Thiamin supplementation should be started as early as possible in patients suspected to have thiamin deficiency. Treatment is safe, inexpensive, simple, and life-saving. Diagnosis is confirmed on a positive response to treatment. (Nutr Clin Pract. 2019;34:558-564)
