Fat Disorder

PRIMARY OBJECTIVE To evaluate the changes in body composition in morbid obese patients following bariatric and metabolic surgery Secondary Objectives: 1. To assess changes in BMR in obese patients following bariatric surgery 2. To evaluate muscles strength and muscle performance parameters in obese patients following bariatric surgery 3. To assess change in inflammatory and metabolic parameters following bariatric surgery 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.

The purpose of this research study is to see if obstructive sleep apnea (OSA) is associated with abnormalities in fat metabolism. Through this research study, the Investigator will evaluate how fat is metabolized in people with and without sleep apnea, what substances the fat tissue releases, and how these substances might change the way the body uses energy and sugar.
