How to Lower Your A1C Levels

What is an A1C?
An A1C is a laboratory test that measures average blood glucose, or blood sugar, control over a period of approximately two to  three months. Red blood cells are made of a molecule – hemoglobin – that picks up oxygen in the blood and gives the blood its color. Glucose sticks to the hemoglobin to make a 'glycosylated hemoglobin' molecule, called hemoglobin A1C.

In addition to your A1C test results, your doctor may now be reporting your Estimated Average Glucose, or EAG.

A1C LevelsThe American Diabetes Association A1C goal is less than 7%. The American Association of Clinical Endocrinologists (AACE) says to work toward a goal of 6.5% or less. However, these are just recommendations. Your individual goal may not be the same. This should be assessed by you and your healthcare provider according to your particular health conditions.

According to the Diabetes Control and Complications Trial (DCCT) conducted from 1983 to 1993 and the follow-up study, Epidemiology of Diabetes Interventions and Complications (EDIC), for every point you lower your A1C levels, you lower your risk of developing a variety of complications:

  • eye disease risk is reduced by 76%
  • kidney disease risk is reduced by 50%
  • nerve disease risk is reduced by 60%
  • any cardiovascular disease event risk is reduced by 42%
  • nonfatal heart attack, stroke, or risk of death from cardiovascular causes is reduced by 57%

Why Does the A1C Matter?
The effects of prolonged high blood sugar levels are not always immediately noticeable, but the signs of continued neglect can show themselves at any time. Potential complications include:

I can't believe it's over two weeks since I've written anything here. Right now, I'm struggling through some serious fatigue, after having spent the last three days in a Passover cleaning frenzy, the previous couple of weeks in a budgeting mess, and most of the past quarter with serious questions about our current lives and our distance from The Other Half's elderly parents. And in between all that, my first two training rides for this year's Tour de Cure. I need to...
