Who these studies look for
Studies commonly set an HbA1c range, a diagnosis duration and a list of allowed or excluded medications. Some also recruit people without diabetes as a comparison group.

Questions
Will I have to stop my diabetes medicine?
Some studies change or pause medicines under close supervision; many add a study treatment on top of your current care. Never change medicines on your own; the study team and your doctor decide this together.
