Effects of Weight Loss Percentage on Vitamin and Mineral Levels in Patients Undergoing Sleeve Gastrectomy

Buse Yazan, Hulya Demir and Nurullah Bulbuller

Background and Objective: The prevalence of obesity has increased rapidly in the past 30 years worldwide. In line with this, bariatric surgery, one of the common treatment methods, has become more frequent. Bariatric surgery could be associated with nutritional deficiencies. The aim of this study was to determine the effect of weight loss percentages on some micronutrient levels in patients undergoing Sleeve Gastrectomy. Materials and Methods: The study was conducted as a retrospective clinical research on 41 obese patients who underwent laparoscopic sleeve gastrectomy (LSG) in a private hospital in Antalya/Turkey. Clinical findings and anthropometric measurements were evaluated at 4 different time points. Results: Vitamin D, vitamin B12, folic acid, sodium, potassium, calcium, phosphorus, iron and magnesium mean values increased compared to pre-operative measurements. Only zinc values linearly decreased, but the mean values were not measured at deficiency in any month. There was a significant negative correlation in between the change of folic acid levels and the change of weight loss percentages from pre-operative to post-operative 1st month measurements. Conclusion: In this study, when the micro nutrients were evaluated alone, without consideration of the weight change, only the level of zinc decreased. In patients with high weight loss rates, the decrease in folic acid values was statistically significant for the post-operative 1st month measurements. Considering this result, folic acid supplements in larger amounts may be recommended to eliminate this risks that may occur in people who lose weight faster. Based on this result, the relationship between folic acid levels according to weight loss percentages should be examined in more detail.
