Obesity is a multifactorial metabolic disease characterized by chronic low-grade inflammation, extracellular matrix (ECM) dysfunction, and systemic metabolic dysregulation. Matrix metalloproteinases (MMPs), especially MMP-2 and MMP-9, are key regulators of ECM remodeling and inflammation in obesity. This narrative review aimed to synthesize current evidence on the effects of bariatric surgery and pharmacological therapies, including GLP-1 and dual GLP-1/GIP receptor agonists, on MMP activity and metabolic outcomes. Literature from PubMed and Scopus (2015–2024) was analyzed, focusing on studies evaluating MMPs, inflammation, and metabolic parameters. Bariatric surgery consistently reduces MMP-9 levels and normalizes MMP-2 activity, contributing to improved ECM integrity, reduced inflammation, and enhanced insulin sensitivity. Pharmacological therapies achieve substantial weight loss and glycemic control but evidence regarding their direct effects on MMP activity remains limited. This review highlights bariatric surgery as the most effective strategy for modulating obesity-related MMP dysregulation and emphasizes the need for further research into the mechanistic effects of modern pharmacotherapy on ECM remodeling.
