The UCLA Metabolic and Bariatric Surgery Program (adult program) and the UCLA Fit for Healthy
Weight Program (adolescent program) are committed to the care of morbidly obese patients.
This study is observational. The investigators plan to evaluate bariatric surgery outcomes
using the BAROS National Database and also to evaluate quality of life pre- and post
bariatric surgery. In addition, the investigators plan to enroll a subgroup of 10
reproductive-age women to evaluate: 1) pregnancy and offspring health, 2) long-term
nutrition, 3) biomarkers/epigenome, and 4) body-composition/bone-density.
