What is PreDiabetes?

Prediabetes is a condition where blood sugar (glucose) levels are higher than normal, but not high enough for the diagnosis of diabetes. This is sometimes called “borderline” diabetes. Prediabetes is an early stage of diabetes. People with prediabetes often don’t have any symptoms at all. Many people with prediabetes will eventually develop diabetes unless they make changes in their eating habits and physical activity levels.


It is important to treat prediabetes because some health problems associated with diabetes may already be starting with prediabetes. 

The best treatment for prediabetes is improving your diet and exercising more.  This can return the blood glucose levels to normal. 

Sometimes a diabetes pill may be prescribed to help lower the blood glucose levels. 


A person with prediabetes WILL NOT automatically develop type 2 diabetes! 

Type 2 diabetes can be prevented by making small changes based upon your doctor's advice. Some examples of these changes include becoming more physically active, reducing the time spent sitting still, developing a plan for healthy meals and snacks and avoiding sugary drinks. 


A person with prediabetes should be checked for type 2 diabetes with lab tests every one to two years. Talk to the doctor about getting tested earlier if any of the symptoms of diabetes develop:

  • increased thirst
  • frequent urination (peeing more) – even during the night
  • blurred vision
  • frequent headaches
  • feeling very tired during the day
  • frequent infections
  • irregular menstrual periods (in girls who have already had their first period)
