What this study is about
The purpose of this research study is to investigate how body weight and weight-loss surgery affect the natural chemicals found in scalp hair over time. We will also find out how common and severe hair thinning/hair loss and muscle loss are in the first 6 months after bariatric surgery.
A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.
