1. Complications or comorbidities of diabetes should be evaluated in older adults, and comprehensive geriatric assessment should be performed to check functional autonomy and degree of aging. [Expert opinion, general recommendation]

2. The glycemic goal is an HbA1c <7.5% but should be individualized considering an older adult’s health condition or degree of aging. [Expert opinion, general recommendation]

3. Optimal nutrition and protein intake and regular exercise are recommended for older adults because these can help prevent CVD and improve the quality of life and control blood glucose levels. [Randomized controlled trial, general recommendation]

4. Upon determining the therapy, consider the risk of hypoglycemia, and avoid excessive or complicated therapy by checking whether any factors affect adherence to the drugs. [Non-randomized controlled trial, general recommendation]

5. Individualize the screening tests for complications and emphasize the dysfunction evaluation. [Expert opinion, general recommendation]

6. Individualize treatments or drugs for the CVD risks based on general health. [Expert opinion, general recommendation]

7. CGM should be recommended for older adults with T1DM to reduce the risk of hypoglycemia. [Randomized controlled trial, general recommendation]

8. For T2DM patients on a multiple insulin injection regimen, continuous glucose measurements should be considered to improve glycemic control and glycemic variability. [Randomized controlled trial, limited recommendation]
