Effects of weight loss percentage on vitamin and mineral levels in patients undergoing sleeve gastrectomy

The study was conducted as a retrospective clinical research with 41 obese patients underwent Laparoscopic Sleeve Gastrectomy (LSG) at Antalya Lara Anatolian Hospital. Data had been collected for 2 years period (01.01.2016-01.02.2018) were evaluated and 41 people were selected among records. Clinical findings and anthropometric measurements of patients were evaluated in the postoperative 1st month, 3rd month and 6th month and preoperative period. Data includes biochemical values which are vitamin D, vitamin B12, folic acid, sodium, potassium, calcium, zinc, magnesium, phosphorus, iron, uric acid, glucose, hemoglobin A1c (HbA1c), parathyroid hormone (PTH), thyroid-stimulating hormone (TSH), albumin, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride and anthropometric measurements which include weight and height. The aim of this study is to determine the effect of weight loss percentages on some micronutrient levels in the first 6 months while bariatric patients were using multivitamin supplementation. When all data was evaluated, the correlation analysis results indicated that the difference in weight loss percentage in patients was not related to the change in micronutrient values except folic acid.
