Understanding Your G7 Readings
The Dexcom G7 provides real-time glucose readings that help you manage your diabetes. Your readings are displayed on the Dexcom app, which is available for iOS and Android devices. You can also view your readings on the Dexcom receiver, which is a separate device that you can purchase.
The G7 measures your glucose levels using a sensor that is inserted under your skin. The sensor sends your glucose readings to the transmitter, which then sends the readings to the app or receiver. The G7 is a continuous glucose monitor (CGM), which means that it provides readings 24 hours a day, 7 days a week.
Glucose Trends
The G7 app shows you your glucose readings in real time, as well as trends over time. You can use this information to understand how your glucose levels change throughout the day and how they are affected by different foods, activities, and medications.
To view your glucose trends, tap on the “Trends” tab in the Dexcom app. You will see a graph of your glucose readings over the past 24 hours, 7 days, or 30 days. You can also zoom in or out on the graph to see more or less detail.
Here are some of the different types of glucose trends that you may see:
| Trend |
Description |
| Stable |
Your glucose levels are staying within a narrow range. |
| Rising |
Your glucose levels are increasing. |
| Falling |
Your glucose levels are decreasing. |
| Spiking |
Your glucose levels are increasing rapidly. |
| Dropping |
Your glucose levels are decreasing rapidly. |
Understanding your glucose trends can help you to identify patterns and make changes to your diabetes management plan. For example, if you notice that your glucose levels are always high after eating a certain type of food, you may want to avoid that food or eat it in smaller portions.
