Through an one-year follow-up, to explore the effect of GLP-1 receptor agonist on bone metabolism in patients with diabetes.

This study is a single-center observational study. After the patients were enrolled according to the standard of admission and exclusion, on the basis of the original scheme, GLP-1 receptor agonists were added and followed up for one year. The indexes of bone metabolism and body fat were measured at several time points (3 months, 6 months, 9 months and 12 months after treatment). Bone mineral density (BMD) was measured at several time points (6 months and 12 months after treatment) to explore the effect of GLP-1 receptor agonists on bone metabolism in patients with diabetes.

Inclusion Criteria:

1. Diagnosed patients with diabetes
2. HbA1c≥7.5%；
3. Willing to sign a written informed consent form and abide by the research plan

Exclusion Criteria:

1. Any of the following drugs or treatments were used within one month before screening: treated with GLP-1RA, GLP-1 analogues, DPP-4 inhibitors, or any other enterotropic insulin analogue
