You’ve probably heard of diabetes. But what about prediabetes?

Like it sounds, if you have “pre-” diabetes, you don’t have type 2 diabetes yet. But the amount of sugar (glucose) in your blood suggests you may be headed in that direction. With prediabetes, blood sugar levels are slightly higher than normal (between 100 and 127 mg/dL). Between 70 and 100 mg/dL is considered normal.

If you are told you have prediabetes, consider it an early warning. It means you need to take steps to put your health first in order to stop or slow the onset of type 2 diabetes. Even at this early stage, higher than normal blood sugar levels can start to damage your heart and circulatory systems. In fact, people with prediabetes are more likely to develop heart disease or a stroke.

Commit to making smart lifestyle changes. Losing excess weight, being more physically active and not smoking can go a long way to getting your health back on track to avoid full-blown diabetes and related problems. Doing so will also help lower your risk of heart disease, too. Use this condition center to learn more about prediabetes, create a list of questions to ask your health care provider and get practical tips.
