The efficacy of long-term treatment with different GLP-1RA (Duragtide, Semaglutide, losenatide, tirzepatide, ebenatide, etc.) was evaluated through 1-4 years of follow-up, and the effects of long-term treatment on blood glucose and body fat of patients.

At present, there has been no evaluation on the efficacy of long-term treatment of different GLP-1RA (Duragtide, Semaglutide, losenatide, tirzepatide, ebenatide, etc.), and the effects of long-term treatment on patients' blood glucose and body fat. This study intends to follow up for 1-4 years. To observe the effects of different GLP-1RA on body fat, insulin resistance, body weight, blood glucose, blood lipids, stomach volume, etc., in patients with type 2 diabetes, and explore the factors affecting the efficacy, so as to provide more evidence-based medical evidence for drug treatment and benefit patients.
