how to PREVENT type 2 diabetes
There's lots of interest in how to PREVENT type 2 diabetes in patients with "pre-diabetes."
There are currently no drugs approved for prevention. Some show promise...but it's not clear if they just mask or delay the onset of diabetes, or actually prevent it.
Metformin (Glucophage, etc) decreases diabetes incidence in patients with impaired glucose tolerance. It also helps patients lose a little weight...about four pounds.
