Doctors worry about people whose blood sugar is elevated but not yet high enough to warrant a diagnosis of full blown diabetes. Such individuals are said to have prediabetes.
Staving Off Diabetes
When this condition is diagnosed, doctors have an effective medication to lower the likelihood that a patient will go on to develop diabetes. The medication, metformin, has long been used to treat diabetes itself.
However, a study of 17,000 adults with pre-diabetes found that relatively few people who could benefit from metformin were being prescribed the drug, only between 3 and 4 percent.
Why Is Metformin Prescribed Infrequently?
The authors hypothesize that doctors may not know of metformin’s benefits for pre-diabetes. That may be in part because the FDA has not approved the medicine for prevention. The American Diabetes Association started recommending metformin be used for this purpose back in 2008.
