Glucose consumption is measured by tracking the levels of glucose in your blood. Here are the primary methods:
Methods for Measuring Glucose Levels
Continuous Glucose Monitor (CGM)
- A CGM uses a tiny sensor that is inserted under the skin.
- This sensor continuously measures glucose levels throughout the day and night.
- The data is typically sent to a device or smartphone for monitoring.
- Example: A person can see patterns in their glucose levels after meals or during exercise.
Blood Sugar Meter
- A blood sugar meter is a portable electronic device.
- It requires a small drop of blood, usually obtained with a finger prick.
- The blood is placed on a test strip, which is inserted into the meter.
- The meter then displays the glucose level.
- Example: This is used for spot checks, such as before meals or before bed.
Comparative Table of Glucose Measuring Methods
| Feature | Continuous Glucose Monitor (CGM) | Blood Sugar Meter |
|---|---|---|
| Monitoring | Continuous, day and night | As needed |
| Data | Real-time glucose trends | Snapshot of glucose at a specific time |
| Invasiveness | Minimally invasive, sensor inserted under the skin | Requires a blood sample from a finger prick |
| User Experience | Provides ongoing data, helpful for identifying patterns | Simple to use for occasional checks |
The reference states, "You can use a device that measures your sugar levels throughout the day and night with a tiny sensor. This is called a continuous glucose monitor (CGM). Or you can test yourself as needed with a portable electronic device that uses a small drop of blood. This is called a blood sugar meter."
Both methods provide valuable information about how your body is processing glucose. Choosing one or the other, or both, can be based on your individual needs and health goals.
