Doctor Discussion Guide
This discussion guide gives you the information you need to speak up, ask questions, and get support.
Before your appointment
When you know what you want to talk about, it can make your time more useful and help you get the care that’s best for you.
What to bring
During your appointment
Being prepared can help you get the most out of your time with your healthcare provider. Here are a few tips for talking about CGMs, like FreeStyle Libre systems.
CGM = continuous glucose monitor(ing)
- Libre systems are covered by Medicare Advantage Part B as durable medical equipment (DME).
- You may need to get approval (prior authorization) from your plan before it covers certain services or supplies.
- Costs may vary depending on your plan.
- You may need to use your plan’s network of doctors to get a prescription.
Other key questions
- How can CGM help me make more informed food choices?
- How much could I lower my A1C if I started using a CGM?
- If a food makes my sugar go too high, what could I eat instead?
- What CGM data should I look at after I exercise?
Ask your healthcare provider for a Libre CGM systems prescription.
And don’t let cost stop you. Libre systems are the most affordable CGMs—even without insurance coverage†1.
Words to know
A1C test2
A blood test that shows your average blood sugar level over the past 3 months. It is also called the hemoglobin A1C or HbA1C test.
Basal insulin3
An intermediate- or long-acting insulin that works slowly throughout the day to keep blood sugar stable between meals and while you sleep.
Bolus insulin3
A fast-acting insulin taken at or before meals to help control the rise in blood sugar after eating.
Glucose (blood sugar)2
A type of sugar your body gets from food and uses for energy. It is the amount of sugar found in your blood.
Hyperglycemia (high blood sugar)2,4
What happens when blood sugar is over 180 mg/dL 1 to 2 hours after eating. It can cause thirst, frequent urination, tiredness, or blurry vision. If not treated, it can lead to serious health problems.
Hypoglycemia (low blood sugar)2
What happens when blood sugar is below 70 mg/dL. It can cause shakiness, sweating, hunger, headache, or confusion. If not treated, severe low blood sugar (below 55 mg/dL) can be dangerous.
Insulin2
A hormone your body makes (or is given as medicine) that helps your body manage blood sugar by allowing it to move from your blood into your cells, where it can be used for energy.
Insulin resistance5
When your body stops responding well to insulin, and it makes more insulin to try to keep up, but it can’t make enough. This causes blood sugar to stay high, which can lead to weight gain, prediabetes, or type 2 diabetes.
Time in range2
The amount of time your glucose stays between 70 mg/dL and 180 mg/dL when using a CGM. This shows how often your glucose is in a recommended range.
