The purpose of this study is to better understand the metabolic and hormonal effects of endoscopic bariatric therapy. Specifically, researchers will examine changes in weight, quality of life, and hormonal levels after various endoscopic bariatric therapies. Study procedures include endoscopic interventions (i.e., endoscopic sleeve gastroplasty), blood draw, medical record review, social worker interviews, dietician follow-ups, and clinical follow-up assessments. The study focuses on overweight/obese individuals who will receive an endoscopic bariatric procedure at Cedars-Sinai. The U.S. Food and Drug Administration has approved the EBT procedures as conducted in this study.
