The goal of this observational study is to learn if surgical weight loss can improve chronic widespread pain in people living with higher BMI who self-identify as Hispanic/Latino ethnicity or non-Hispanic Black based on the United States census racial categories.

The goal of this observational study is to learn if surgical weight loss can improve chronic widespread pain in people living with higher BMI who self-identify as Hispanic/Latino ethnicity or non-Hispanic Black based on the United States census racial categories. The main questions the study aims to answer are:
1. Do pain at rest (primary outcome) and movement-evoked pain (secondary outcome) improve after bariatric surgery?
2. Do pain processing and joint function change after bariatric surgery?
3. Are pain processing and joint function associated with clinically significant pain change after surgical weight loss?
Researchers will compare pain and function before and 6 months after bariatric surgery in a single cohort.
