What is Prediabetes?

Prediabetes is a condition identified by a blood test your doctor orders.  Many people find out through a routine physical. If your doctor tells you your blood glucose values are higher than normal, but not high enough to be diagnosed as having diabetes.   It can be diagnosed by 3 different blood tests in the laboratory–fasting glucose test in which someone has not eaten for at least 8 hours, a 2 hour (75 gram) glucose test when you are asked to drink a sugary solution and then a blood is taken to see how your body handles a load of “sugar”, or an A1C or estimated average glucose test which does not have to be performed in a fasting state and reflects the average glucose levels over a 3 month period.
