Knowing My Numbers

... Diabetes Management Numbers Explained

When you’re trying to manage your diabetes, it’s all about the numbers. While you might immediately think about your daily blood sugar numbers, there are additional numbers to know. By keeping track of important numbers, you lower your risk of serious complications in the future.

What numbers do you need to know? What do they mean? What should your numbers be? Here’s a closer look at the most important diabetes management numbers you’ll want to track.

Daily Blood Sugar Numbers

Daily blood sugar checks help you see how well you’re managing your diabetes. And managing your diabetes means you have a lower risk of developing more serious health problems.

When you check your blood sugar, you can start seeing what makes those numbers go down or up. You may notice when you’re more active, your blood sugar numbers go down. When you eat certain foods or get stressed, you may notice those numbers go up.

A blood glucose meter lets you check your blood sugar. Target blood sugar levels generally should be1:

Fasting or before-meal blood sugar: This is your blood sugar number before a meal. It is usually your lowest number. It is best between 4.0 and 7.0 mmol/L.

After-meal blood sugar: This is your blood sugar number two hours after a meal. It is usually your highest number. It is best for your blood sugar readings to be lower than 10.0 mmol/L.

Remember, your healthcare team may also have target goals they want you to work to meet. Talk to your doctor about your personal target blood sugar level.

HbA1c Numbers

An HbA1C test lets you see your average blood sugar level over the past two or three months. Here are a few important things to know about your HbA1C:

  • You should test your HbA1c test every 3-6 months2
  • You may need to have your HbA1c checked more often if your treatment changes or your number is above your target goal

Blood Pressure Numbers

Blood pressure refers to the force of blood that is pumping through your arteries when the heartbeats. People with diabetes are twice as likely to have high blood pressure3. When left untreated, high blood pressure can increase the risk of heart disease and stroke.

In general, your target blood pressure range should be 120/80 mmHG or lower4.  It’s important to talk to your healthcare team about your unique blood pressure goals.

Cholesterol Numbers

If you have diabetes, high cholesterol is another risk factor for heart disease you need to watch. Diabetes can worsen your cholesterol levels5. Even if you’re managing your blood sugar, you may have decreased good cholesterol and higher bad cholesterol levels.
