Role of Glucagon-Like Peptide-1 Receptor Agonists on the Weight Loss of Individuals with Type 2 Diabetes: A Systematic Review

Abstract

Obesity is highly associated with type 2 diabetes mellitus (T2DM), both of which can be simultaneously treated with glucagon-like peptide-1 receptor agonists (GLP-1RAs). There are many antidiabetic drugs that can be used for the treatment of T2DM. These drugs have vast modes of action and therapeutic uses. However, they also have different side effects. Some of these side effects, such as weight changes, are sometimes desirable while others are not. This review examines the literature on how GLP-1RA affects both blood glucose and body weight in patients with T2DM and obesity. In this context, GLP-1RA plays a critical part by controlling not only the blood glucose level but also weight. We followed Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines and searched for articles from PubMed and Google Scholar databases that reported on T2DM, obesity, and GLP-1RA functions. We selected 13 articles that showed the benefits of GLP-1RA in managing both T2DM and obesity. Our review suggests that GLP-1RA is an innovative therapy that can address both conditions simultaneously.
