Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have emerged as a promising therapeutic option beyond their established role in managing type 2 diabetes mellitus (T2DM) and obesity. Recent research has highlighted their beneficial effects on liver, kidney, and cardiovascular health, mediated by both direct and indirect mechanisms. In the liver, GLP-1 RAs contribute to the improvement of metabolic dysfunction-associated steatotic liver disease (MASLD) by reducing hepatic fat accumulation, inflammation, and oxidative stress. Additionally, they enhance insulin sensitivity and lipid metabolism. Similarly, in diabetic kidney disease (DKD), GLP-1 RAs exhibit renoprotective properties by mitigating inflammation, oxidative stress, and glomerular hypertension. Furthermore, they promote natriuresis and stabilize renal function. Moreover, GLP-1 RAs present significant cardiovascular benefits, including improved myocardial function, reduced atherosclerosis progression, enhanced endothelial health, and decreased major adverse cardiovascular events (MACEs). Additionally, emerging evidence suggests GLP-1 RAs may exert substantial neuropsychiatric benefits, including reductions in depressive symptoms, anxiety, substance use behaviors, and lowering the risk of Alzheimer's disease, Parkinson's disease, and other dementias likely mediated by the modulation of neurotransmitter systems and neuroinflammation. Genetic polymorphisms in the GLP1R gene also impact the therapeutic response, highlighting the importance of personalized medicine in optimizing GLP-1 RA efficacy. This review synthesizes preclinical and clinical evidence supporting the multifaceted effects of GLP-1 RAs across multiple organ systems, highlighting their therapeutic potential beyond glycemic control. As research advances, further exploration of their mechanisms of action and long-term clinical outcomes, safety and effectiveness across diverse patient populations will be essential in optimizing their use in treating metabolic and neuropsychiatric conditions.
