Aims. To compare glucose - lowering and weight reduction capacity of bypass operations (gastric bypass (GB), biliopancreatic diversion (BPD) vs GLP-1 agonist liraglutide 3.0 mg (models of maximum incretin effect) for 6 months. Materials and methods. 46 patients with type 2 diabetes and long history (≥10 years) of obesity were divided into 2 groups: surgery - group (n=23) and liraglutide - group (n=23), where liraglutide 3.0 mg in dose - escalation manner was added to baseline glucose - lowering therapy. Anthropometric parameters, HbA1c and insulin resistance (IR) by hyperinsulinemic euglycemic clamp (M-value) were measured before and 16 weeks after the intervention. With the stabilization of glycemia (≤6.5 mmol/l at fasting state, ≤8 mmol/l postprandial) the initial glucose - lowering therapy was canceled. Results and discussion. Both surgery and liraglutide 3.0 mg provided target HbA1c in 16 weeks. Bypass operations led to elimination of glucose - lowering therapy in 82.6% patients due to a more significant weight reduction and decrease in IR. In liraglutide - group previous glucose - lowering therapy was cancelled in 78.3% patients, mainly receiving baseline mono - and two - component therapy. The most significant difference between interventions was achieved in BMI (-8.9 kg in surgery group vs -3.8 kg in liraglutide group, p
