Organic Pollutant Build-Up in Body Fat and Stomach Tissue Linked to Obesity Levels

This study looks at whether certain environmental chemicals, called organic pollutants, build up in the body fat and stomach tissues of people with obesity who are having weight-loss (bariatric) surgery. These pollutants can come from things like plastics, pesticides, or industrial waste, and may affect health in different ways. The investigators will measure the amount of these pollutants in tissue samples taken during surgery and see if the levels are different in people with mild, moderate, or severe obesity. By understanding these patterns, the investigators hope to learn more about how environmental factors may influence obesity and related health problems. The findings could help guide future prevention and treatment strategies for patients.
