While you can learn a lot from looking at your blood sugar responses after eating individual foods and meals, what matters most is the overall shape of your curve over time.

Avoiding large, repeated blood sugar spikes and dips throughout the day is the ultimate goal!

Here are some things to look out for while you’re wearing your sensor:

  • The overall shape of your curve: Notice the overall shape of your curve over time. Does it look like the Rocky Mountains or the rolling hills of England?

  • Range: How much does your blood sugar vary throughout the course of your day? What is the range between your highest and lowest readings? In general, a smaller range is more desirable.

  • Fasting glucose: What are your blood sugar levels like when you wake up? Around 100 mg/dL (5.6 mmol/L) or lower is considered ‘normal’ for people without diabetes.

  • Clearance time: How long does it take your blood sugar to return to normal after a meal? For people without diabetes, blood sugar levels will generally return to baseline levels 2-3 hours after eating.

  • Spikes: When does your blood sugar spike? How high does it go? In general, we should aim to avoid increasing our glucose levels by more than 30 mg/dL (1.7 mmol/L) after eating.

  • Crashes/dips: Does your blood sugar dip below baseline after eating any foods or meals? Notice whether this leaves you feeling feel more hungry, tired, or irritable.
