    Obesity and type 2 diabetes mellitus significantly increase morbidity and mortality, with cardiovascular diseases being the leading cause of death in this population.

  • 2

    Metabolic and bariatric surgery (MBS) leads to substantial weight loss and improved glycemic control, with diabetes remission rates between 31% and 56%.

  • 3

    MBS significantly reduces major adverse cardiac events and all-cause mortality, particularly in obese patients with type 2 diabetes.

  • 4

    GLP-1 receptor agonists (GLP-1 RAs) also improve metabolic outcomes, showing 15-25% weight reduction but can lead to gastrointestinal adverse events.

  • 5

    This systematic review aims to compare the long-term effects of MBS and GLP-1 RAs on mortality and major cardiac events in obese patients with type 2 diabetes.
