What is Pre-Diabetes?

Diagnosis, Treatment, and Prevention
  -- By Liza Barnes & Nicole Nichols, Health Educators
Before developing the serious health condition of type 2 diabetes, a person will almost always have pre-diabetes beforehand. But pre-diabetes is a condition without symptoms, meaning that many people can have it without even knowing it. Left unchecked, pre-diabetes can lead to full-blown type 2 diabetes, heart disease and stroke. Luckily, pre-diabetes can be diagnosed with a simple test, and treatment can prevent many health problems and complications. Here's what you need to know to control pre-diabetes before it gets control of you.

Diabetes Basics
Under normal circumstances, the glucose (sugar) levels in your blood rise after you eat a meal or snack. In response, your body produces a hormone called insulin, which is needed for the body to convert the glucose in your bloodstream into usable energy. But if insulin isn’t available, or if the body isn’t using it correctly, your blood glucose will remain elevated, and that can be harmful to your body. This is a condition known as diabetes. People who have higher-than-normal blood glucose levels that aren’t quite high enough to be diagnosed as type 2 diabetes have pre-diabetes. In the past, individuals with pre-diabetes would have been considered "borderline diabetic."

Who's at Risk?
Over 50 million Americans over the age of 20 have pre-diabetes, according to the American Diabetes Association. If you have any of the risk factors for type 2 diabetes, including uncontrollable factors like age and race, and/or controllable risk factors like obesity and physical inactivity, then you are also at risk for pre-diabetes.

Most of the time, pre-diabetes is asymptomatic (shows no symptoms), but some people will experience some general diabetes symptoms like extreme thirst, frequent urination, fatigue and/or blurred vision.

If you fall into any high-risk categories or experience any of the symptoms above, then visit your health care provider for a blood glucose test as soon as you can. Early diagnosis and treatment are crucial steps, as they can prevent the development of type 2 diabetes and its serious health consequences. <pagebreak>

Testing & Diagnosis
There are two tests commonly used to diagnose diabetes and pre-diabetes: a fasting plasma glucose (FPG test) and an oral glucose tolerance test (OGTT). <pagebreak>
Treatment & Prevention
While pre-diabetes in itself isn’t necessarily dangerous, the fact is that many people with pre-diabetes will develop type 2 diabetes within 10 years.

If you have pre-diabetes, realize that you’re fortunate to have found out while there is still a lot you can do to prevent or delay the development of type 2 diabetes. Here are some preventative measures: If you have pre-diabetes, work closely with your doctor to create a plan of sensible lifestyle changes that will work for you. The complications of diabetes—heart disease, stroke, blindness, and more—can be avoided by taking these proactive steps today.
