Living in Range

When you find your mind wandering—thinking about the future—what do you see? Whether you dream about taking photos somewhere amazing, starting a family, or simply having more daily energy and sleeping through the night, keeping your blood glucose in line can help you achieve it.

Living in Range

Sometimes it can seem like diabetes is all about the numbers. But your efforts to stay within your target glucose ranges before and after meals, as well as meeting your HbA1c goal, are ultimately about feeling your best today and for years to come.

Self-Checks, CGMs, and HbA1c: Why You Need a Complete View
To track your self-care progress, your healthcare provider will look at multiple metrics side-by-side to get a complete clinical picture.1

  • Finger-Stick Self-Checks (BGM): A traditional finger prick shows your blood glucose level at a single, exact point in time. You can plot individual results to see immediate patterns, such as how a specific breakfast impacts you.
  • The HbA1c Test: This lab test measures the percentage of glycated hemoglobin in your red blood cells, reflecting your average blood glucose over the past 2 to 3 months to provide a broader, long-term view.1
  • Time in Range (TIR): Because HbA1c is strictly an average, it cannot show daily fluctuations on its own. Modern diabetes care uses Continuous Glucose Monitors (CGMs) to measure TIR—the percentage of time your blood sugar stays within your safe target zone (typically 70 to 180 mg/dL).2

The Danger of a Deceptive Average
Consider this example: A person whose blood sugar wildly swings from 50 mg/dL to 250 mg/dL throughout the day could have an average blood glucose of 150 mg/dL. This translates to an HbA1c of right around 7%.2

On paper, a 7% A1C looks very healthy. In reality, a daily "roller coaster" is not safe. A drop to 50 mg/dL is dangerously low (hypoglycemia), and spiking up to 250 mg/dL causes exhaustion, extreme thirst, and brain fog.[1] Tracking your Time in Range reveals these dangerous spikes and dips that an A1C average hides.

Better Today and Better Tomorrow
Controlling your blood glucose means significantly lowering your risk of chronic health complications years down the road, but you do not have to wait decades for your efforts to pay off.

Effectively managing your daily blood glucose and minimizing extreme swings means you will experience more consistent energy, sleep better, and enjoy a more stable mood every single day.3 Staying steady "in range" keeps you feeling your best so you can comfortably tackle whatever is on your bucket list—whether that is learning to play golf, starting your own business, or going dancing this Saturday night.
