A new study shows that wearable glucose monitors may help adults with type 2 diabetes manage their blood sugar, even if they do not use insulin. A glucose monitor, also called a CGM, is a small device that measures sugar levels in the body all day and night. In the study, 283 people from 22 clinics in the United States either used a Dexcom G7 monitor or continued with their usual care for six months.

The main reason for the study was to see if glucose monitors could help more people, not just those using insulin. Usually, these monitors are used by people who inject insulin, but many people control their diabetes with tablets and lifestyle changes. The monitor lets users see how food, exercise, and other activities change their blood sugar.

After six months, people who used the device had better blood sugar control than those who did not. Their average sugar levels dropped more, and they spent more hours each day in a healthy range. This means wearable monitors could become helpful for more people with type 2 diabetes in the future.
