Image for glucose tests Just as pre-cancer may be detected and removed before turning into cancer, discovery of diabetes in its earliest stages can help prevent further development of the condition.

Blood sugar levels that are higher than normal, but not high enough to be called diabetes, are classified as prediabetes. Prediabetes is also called impaired glucose tolerance or impaired fasting glucose. Evidence indicates that people with prediabetes can take steps to return their blood sugar levels to a normal range. This can prevent or delay complications that are linked to diabetes.

If you have prediabetes, then you are at risk for type 2 diabetes and other serious conditions, like heart attack and stroke.

Other long-term health problems can result if you do not have good control over your blood sugar levels. Complications related to type 2 diabetes include but are not limited to:

  • Blindness
  • Impotence
  • Kidney disease
  • Nerve damage
  • Limb amputation
