Muscle loss after MBS appears largely adaptive, proportional to weight loss, and does not consistently impair functional capacity. Absolute and relative changes should be interpreted in the context of overall weight reduction. Adoption of standardized outcome measures and obesity-specific normative data for muscle quantity and function is needed to improve the early detection of sarcopenia and to distinguish adaptive muscle loss from clinically meaningful impairments after MBS.
