More than 84 million Americans – or, one in three adults – have prediabetes, and 90% of them don’t know they have it, according to the CDC. Don’t let the “pre” fool you - prediabetes is a serious condition that can lead to type 2 diabetes and raise your risk for heart disease and stroke.

The good news is that prediabetes can be reversed – but only if you get a diagnosis and make lifestyle changes, like losing weight, eating healthier, and being more active – changes that will help prevent or delay the onset of type 2 diabetes.

Here’s what you can do:

Go to DoIHavePrediabetes.org to take a 1-minute risk test. (Since January 2016, more than 2 million people have visited DoIHavePrediabetes.org, and close to 2 million people have completed the prediabetes risk test.)

Talk to your doctor about your prediabetes risk and get a blood test to confirm a potential diagnosis.

If you do have prediabetes, enroll in the CDC’s National Diabetes Prevention Program. (DoIHavePrediabetes.org shows them how to sign up.)

Prediabetes is reversible

The CDC says that prediabetes can be a health wake-up call for many and with early diagnosis, the condition can be reversed. And remember: anyone can be that 1 in 3.
