Sponsor's own description

The aim of the study primarily was to investigate the value of zinc to copper ratio as possible biomarker of trace elements imbalance in morbidly obese subjects undergoing LSG. Secondly to correlate zinc to copper ratio with lipocalin 2 (Lcn2) with respect to Anthropometric measurements and other metabolic biomarkers. Prospective study will be carried out on 120 morbidly obese adult subjects with a body mass index (BMI) score above 40 along with presence of obesity-related comorbidity. Investigations will be measured preoperative and 9 months postoperative after performing Laparoscopic sleeve gastrectomy; for Body mass index (BMI) and waist circumference. As well as for complete blood count and biochemical biomarkers as fasting blood glucose, lipid profile, serum iron and ferritin. Serum Ceruloplasmin, Zn and Cu levels, followed by calculation of zinc to copper ratio. CRP, serum insulin, serum leptin and lipocalin-2 (Lcn2) will be determined.
