Abstract

GLP-1 receptor agonists (GLP-1RAs) improve glycaemic control and beta-cell function with a low risk of hypoglycaemia in people with type 2 diabetes.

  • GLP-1RAs may have cardioprotective effects, as suggested by preclinical studies.
  • Clinical trials indicate GLP-1RAs can positively affect hypertension and dyslipidaemia in individuals with type 2 diabetes.
  • Significant weight loss has been observed in people with type 2 diabetes and in obese individuals without diabetes using GLP-1RAs.
  • GLP-1RAs slow gastric emptying, but appetite regulation in the brain may be the primary mechanism for weight loss.
  • In rodent models, GLP-1RAs have shown neuroprotective effects in conditions like stroke and Alzheimer's disease.
  • Potential adverse effects of GLP-1RA treatment may include gastrointestinal issues, increased heart rate, and renal injury.
