Obesity is recognised as an important risk factor for type 2 diabetes, inducing insulin resistance and pancreatic beta-cell dysfunction. These obesity-related defects tend to progress following weight gain and can eventually lead to worsening hyperglycaemia over time. Thus, effective weight management is crucial for glycaemic control in overweight and obese patients with type 2 diabetes. Current standard strategies for weight management in these patients include lifestyle interventions and pharmacotherapy. Bariatric surgery has become a promising new option for the treatment of obese patients with type 2 diabetes and in recent years incretin-based therapies have become available, which exhibit favourable effects on body weight. Herein, the efficacy of available weight loss interventions is assessed and the role of newer antidiabetic agents examined, focusing on incretin-based therapies.
