Abstract:【Objective】To explore the preferred treatment for overweight and obese patients with type 2 diabetes mellitus(T2DM)in the early stage.【Methods】A total of 90 overweight or obese T2DM patients who were treated in our hospital were selected,and the patients were randomly divided into the control group,the Dapagliflozin group and the Dapagliflozin+Loxenatide group.The control group was treated with metformin,the Dapagliflozin group was treated with dapagliflozin,while the Dapagliflozin+Loxenatide group was treated with polyethylene glycol loxenatide for six mouths and then treated with dapagliflozin for half a year.All patients were treated continuously for 1 year.Weight,body mass index(BMI),waist circumference,glycated hemoglobin(Hb Alc),fasting plasma glucose(FPG),fasting insulin(FINS),homeostasis model assessment of insulin resistance(HOMA-IR),adiponectin and leptin were recorded before and after treatment.【Results】Compared with before treatment,weight,BMI,waist circumference,HbA1c,FPG,FINS,HOMA-IR and leptin in each group decreased after treatment(P<0.05).The difference of body mass,BMI and waist circumference before and after treatment was significantly different among three groups(P<0.05).The difference of FPG,FINS,HOMA-IR before and after treatment was significantly different among three groups(P<0.05).The difference of HbA1c,leptin,adiponectin before and after treatment was significantly different among three groups(P<0.05).【Conclusion】The treatment of polyethylene glycol-loxenatide sequential combined with dapagliflozin for early obesity or overweight T2DM can decrease blood glucose and significantly reduce body weight,and improve insulin resistance,which may be the preferred treatment for early obesity or overweight T2DM.
