Understanding Glucose Monitoringing Devices
Before diving into graph interpretation, it helps to understand how different glucose monitoring devices collect anddisplay data. The type of device you use determinates thee resolution of your graphs and the kind of trends you can observe.

Key Components of Glucose Graphs andd Charts

The Glucose Level Axis (Y- Axis)
The vertical axis shows glucose concentrations, usually in mg / dL (milligrams per deciliter) in thee United States or mmol / L (millimoles per liter) in many tear countries. Most graphs have a scale from about 40 mg / dL (2.2 mmol / L) to 400 mg / dL (22.2 mmol / L) in many teur / L). Understanding your target rangee relative to this axis is key. Look for horizontal lides or shar bands indicating the loold (often 70 md) hd (often 70 mg / dht hamboold (ofted (often 180d).
Wskaźniki Target Range
Mer most diults with diabetes, thee American Diabetes Association supportes a range of 70- 180 mg / dL. Time in range (TIR) is a metric many clinicians use - aiming for more than 70% of readings with rangin that zone.

Pie Charts or Time- in- Range Charts
Many CGM reports include a piee chart showing the vibrage of time spent in three zone: below targemia (hypoglycemia), in targemia (euglycemia), and above target (hyperglycemia).

Identify meals that cause excessive spikes. If your graph shows a sharp rise after breakfast, consider reducing carbohydates, choosing lower glycemic index foods, or adjusting the timing of yourr insulilin. Some contrille find that pre- bolusing (takting insulin 15- 20 minutes before eating) contriantly flatens post- meal curves. Experiment with one change at a time and note the effect on the graph over thee next fedays.
