Impact of BAriatric Surgery on Body COmposition, Basal Metabolic Rates and Muscle functions in Morbid Obese Patient: A Prospective Observational Study

Prospective Observational Cohort study, In this study, morbidly obese patients undergoing bariatric surgery will be assessed at baseline and followed by 3rd  and 6 months to evaluate various physiological and biochemical changes. Anthropometric measurements including height, weight, BMI, and waist-hip ratio will be recorded. Body composition will be assessed using Bioelectrical Impedance Analysis (BIA), which will provide data on percentage body fat (PBF), segmental muscle mass (SMM), segmental fat mass (SFM), and skeletal muscle index (SMI). Basal metabolic rate (BMR) will also be measured through BIA. Muscle strength will be evaluated using a hand grip dynamometer, while muscle performance will be assessed via gait speed using the 6-meter walk test. Inflammatory markers such as high-sensitivity C-reactive protein (HsCRP), erythrocyte sedimentation rate (ESR), and interleukin-6 (IL-6) will be analyzed. Additionally, metabolic parameters including thyroid-stimulating hormone (TSH), fasting and postprandial blood glucose, HbA1c, and lipid profile will be measured to understand the systemic effects of the surgery.
