Overview

Comparative review examines the effectiveness, limitations, and costs of incretin therapies and metabolic bariatric surgery for obesity, highlighting evolving care pathways and clinical evidence gaps.

Key Points

  • To compare clinical evidence regarding the effectiveness, limitations, and financial costs of incretin-based therapies versus metabolic bariatric surgery in obesity management.
  • Synthesized comparative clinical evidence on the efficacy, safety, limitations, and costs of incretin-based therapies and metabolic bariatric surgery.
  • Evaluated evolving clinical care pathways and outlined key evidence gaps needed to clarify future obesity treatment paradigms.
  • Incretin-based therapies challenge traditional surgical interventions by delivering robust weight reduction, though differences in durability, invasiveness, and lifelong costs remain pivotal distinctions.
  • Defining the optimal complementary or standalone roles of pharmacotherapy and surgery requires addressing major evidence gaps in long-term outcomes, adherence, and health system economics.
