Background:Glucagon‐like peptide 1 receptor agonists (RA) are novel agents used in the management of type 2 diabetes (T2D) and obesity. Although highly effective, the response to treatment may vary significantly among patients.
Objective:This perspective review aims to summarise the current knowledge about markers of poor or good response to GLP‐1 RA, highlighting the possibility of tailoring treatment strategies and reducing costs associated with T2D and obesity treatment.
Methods:A comprehensive literature search was conducted using PubMed, NCBI, and Scopus databases, focussing on studies published between 2016 and 2024 that evaluated factors influencing treatment outcomes with GLP‐1 RA.
Results:Several markers, including baseline HbA1c levels, ghrelin and glucose‐dependent insulinotropic polypeptide (GIP) levels, specific gut microbiome composition, b‐cell function, and genetic markers, were identified as factors associated with treatment response.
Conclusion:Understanding predictive markers of response to therapy can enhance precision‐based medicine for the selection of patients eligible for GLP‐1 RA, improving clinical outcomes and optimising diabetes management.
