Brief Summary
The goal of this observational study is to learn about the long-term effects of GLP-1RAs (Ozempic, Wegovy, Rybelsus, Mounjaro, or Zepbound) in adolescents and young adults aged 12-21 who will start taking this drug for weight management. The main question it aims to answer is: How does starting GLP-1RAs impact eating behaviors and mental health symptoms? Participants starting to take GLP-1RAs as part of their medical care for weight management will answer online survey questions about their experience taking the drug for 1 year.
