Understanding blood sugar

 

Blood sugar can be measured at any time of day.  Understanding blood sugar can be hard, but it doesn't have to be!

Information you need to know:

isc clock

  1. It is important to know (and write down) what time of day you measured your blood sugar (for example, 3:15 PM).
  2. Also, write down how much time has passed since you last ate and drank (for example, "ate a turkey and cheese sandwich on white bread 2 hours ago").

***Knowing time of day and recent foods/drinks will help you understand your blood sugar.***

"Fasting" Blood Sugar...just a shapshot of your blood sugar control on an empty stomach

What is my "fasting" blood sugar goal? The goal for "fasting" blood sugar is often to be between 70 and 150 (mg/dL). Ask your doctor what your goal is.

"Post-Prandial" Blood Sugar...a shapshot of your mealtime blood sugar control

If you ate a meal about 2 hours ago, this is called a "2-hour post-prandial" blood sugar.  In people without diabetes, blood sugar is highest 1 hour after eating and is usually less than 140 (mg/dL). What is my "post-prandial" blood sugar goal? The goal for "2-hour post-prandial" blood sugar is often to be less than 180 (mg/dL). Ask your doctor what your goal is.

A1c...It's like a 3-month video of your blood sugar control

There is a way to measure your long-term blood sugar control.  It's called A1c. A1c is short for hemoglobin A1c.  A1c measures your sugar control over 3 months.  What is my A1c goal? The best goal for A1c is to be less than 6.5%. Ask your doctor what your goal is.
