What is Prediabetes?
Prediabetes is a condition in which blood glucose levels are higher than normal, but are not high enough to be considered for a diagnoses of diabetes. People with prediabetes are at an increased risk for developing type 2 diabetes and for heart disease and stroke. Other names for prediabetes are impaired glucose tolerance and impaired fasting glucose.
In 2012, 86 million Americans age 20 and older had prediabetes; this is up from 79 million in 2010
People with prediabetes are likely to develop Type 2 diabetes within 10 years.
Can Prediabetes Be Prevented?
Studies have shown that people with prediabetes can prevent or delay the development of Type 2 diabetes by 58%. Changes in lifestyle can help. These lifestyle changes include but not limited to:
Modest weight loss (by 5-10%)
Regular exercise or physical activity (30 minutes daily) at least 5 days a week.
How Do I Find Out If I Have Pre-Diabetes?
There are two types of glucose (blood Sugar) tests that are used to tell if you have diabetes or pre-diabetes. Both test require a fasting period.
I. Fasting Blood Glucose Test
Pre-Diabetes glucose level = 100-125 mg/dl
II. Oral Glucose Tolerance Test
Involves a special glucose drink and a blood test done two hours later.
Normal glucose level = is 139 mg/dl or below
Pre-diabetes glucose level = 140 - 199 mg/dl
It is normal for testing to be repeated to confirm diagnosis. Visit your doctor or healthcare professional to obtain a fasting blood test or glucose tolerance test to tell if you have diabetes or pre-diabetes.
