People with prediabetes have higher blood sugar than normal, but not high enough for an official diabetes diagnosis. Prediabetes puts you at increased risk of developing type 2 diabetes, heart disease, and stroke.

Prediabetes often goes unnoticed

You can have prediabetes for years wtihout symptoms. This means you likely won't know you have prediabetes until serious health problems show up. Talk to your doctor about getting your blood sugar tested if you have any of the risk factors for prediabetes, including:

• Being overweight
• 45 years or older
• Having a parent, brother, or sister with type 2 diabetes
• Being physically active less than 3 times a week
• Ever having gestational diabetes (diabetes during pregnancy) or giving birth to a baby who weighed more than 9 pounds.

Race and ethnicity are also a factor. African Americans, Hispanic/Latino Americans, American Indians, Pacific Islanders, and some Asian Americans are at higher risk.
