Diabetes and Glucose Control

Diagnosis Of Type 2 Diabetes

Conventional Diagnostic Approach

Conventional diagnostic criteria for diabetes include:

  • Fasting plasma glucose 126 mg/dL or greater (fasting glucose between 100 mg/dL and 125 mg/dL is considered “impaired fasting glucose” or “prediabetes”).
  • Non-fasting plasma glucose level 200 mg/dL or greater with diabetes symptoms.
  • Plasma glucose level 200 mg/dL or greater 2 hours after a 75-g oral glucose tolerance test.
  • Glycated hemoglobin (HbA1C) 6.5% or greater. An HbA1C of 5.7–6.4% is considered prediabetes.

Confirmation with a repeat or second test is necessary. A repeat of the same diagnostic test is preferred, though abnormal results on two different tests are also acceptable for diagnosis (O’Connor 2015; Inzucchi 2012b; Bansal 2015).

Life Extension’s Approach

A shocking number of people unknowingly suffer from chronic high blood sugar or frequent post-meal glucose surges. The longer or more frequently your blood sugar is elevated, the more time it has to cause cellular and tissue damage and promote insulin resistance, predisposing you to degenerative disease and accelerated aging. In fact, the toxic effects of excess blood sugar may be a leading cause of premature death (Nwaneri 2013; Seshasai 2011; Ding 2014; Kalyani 2013; De Tata 2014; Huang 2015).

Life Extension believes everyone should strive for optimal glucose control, regardless of whether or not they are diabetic. This means taking action to improve your glycemic control if your fasting glucose is over 85 mg/dL or your HbA1C is higher than 5.0%. Studies have shown the incidence of age-related disease begins to increase as fasting blood sugar levels climb above 85 mg/dL—a level currently accepted as normal by conventional medicine (Kato 2009; Muti 2002; Nichols 2008; Bjornholt 1999; Simons 2000; Meigs 1998; Tirosh 2005; Gerstein 1999; Coutinho 1999).
