Comparing glucose monitors and standard testing in cystic fibrosis

This study is testing whether a small wearable glucose monitor (called the Dexcom G7) can be just as useful as the standard oral glucose tolerance test for detecting early blood sugar problems in young people with cystic fibrosis. Researchers want to see if the glucose monitor gives doctors the same helpful information in an easier, less burdensome way. As people with cystic fibrosis live longer thanks to new treatments, catching diabetes early becomes increasingly important.

Right now, doctors use a standard test that requires patients to drink a sugary solution and have blood drawn at specific times—it's uncomfortable and many patients skip it. This study aims to find out whether a glucose monitor worn for a week can replace this test or work alongside it, making it easier for young people to get screened regularly and catch blood sugar problems before they become serious.
