Editor's note
A commentary rather than primary data, this paper raises a plausible concern that GLP-1-associated weight loss in adolescents could attenuate peak muscle and bone accrual. The authors acknowledge longitudinal pediatric evidence is limited, so the musculoskeletal caution is precautionary rather than established. Semaglutide is central to the discussion but the piece offers guidance, not new outcome data.
Plain-language abstract
This perspective piece considers how GLP-1 medications such as semaglutide, used for adolescent obesity, may affect muscle and bone development during growth. The authors argue for pairing these medications with resistance training and adequate protein to preserve lean mass.
