What is prediabetes?
Before developing type 2 diabetes, most people have prediabetes. This is when their blood sugar is higher than normal but not high enough yet for a type 2 diabetes diagnosis. In the United States, about 115 million adults have prediabetes; that’s more than 2 in 5.

There are usually no signs when you have prediabetes, which is why 8 in 10 people don’t know they have it. You can have prediabetes for years and not know.
