NCT ID NCT07422987
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This study looks at how estrogen levels influence body composition and muscle function in midlife women (ages 35-60) who are starting a GLP-1RA medication for weight loss. Researchers will measure changes in weight, muscle mass, bone density, and strength over time. The goal is to understand whether estrogen plays a role in how these drugs affect lean mass and bone health.
