The goal of this clinical trial is to learn if continuous glucose monitoring system works to improve glucose control in non-insulin-treated older adults with type 2 diabetes. The main questions it aims to answer are:
* Dose the use of continuous glucose monitoring system improve glucose control in older adults with type 2 diabetes treated with oral antidiabetic drugs only? * Dose the use of continuous glucose monitoring system affect psychological outcomes in older adults with type 2 diabetes treated with oral antidiabetic drugs only? Researchers will compare continuous glucose monitoring to standard blood glucose monitoring to see if continuous glucose monitoring works better in glucose management.
Participants will:
* Wear continuous glucose monitoring every 2 months or standard blood glucose monitoring for 6 months * Visit the clinic once every 2 months for follow-up * Keep a diary of their blood glucose when continuous glucose monitoring was not used
