Over a big group dinner the other night, I found out that there is a considerable amount of confusion about both what CGM is and the differences between CGM and insulin pumps. Hopefully this blog will help shed some light on these questions!
1. What information will I get from Continuous Glucose Monitoring (CGM)?
CGM measures glucose in the tissue fluid throughout the day and night, about every five minutes, and sends the collected data to a receiver, phone, or insulin pump. This information can tell you how your glucose levels are trending, so you can make better decisions about your insulin dosing.
2. How can CGM help me manage diabetes better?
A continuous glucose monitor is a small wearable device system that tracks your glucose throughout the day and night, notifying you of highs and lows so you can take action. A CGM system consists of 3 parts:
- Small, under-the-skin sensor that measures glucose levels
- Transmitter that attaches to the sensor and transmits data
- Receiver that displays real-time glucose information
3. Are there additional benefits of CGM?
Continuous glucose monitoring can help you make the best possible decisions since you'll be able to see your trend data provided by the CGM instead of basing choices only on a number from a blood glucose meter reading. You can also set thresholds for high and low numbers, and the CGM will alert you when it senses your glucose levels have moved out of the safe range you set.
4. Is CGM covered by insurance?
Yes, CGM is covered by many insurance plans. Our Insulin Pump & CGM Therapy Team can help you obtain a prescription from your doctor, navigate the insurance verification process, and place your CGM system order. They also help customers with CGM supply refills.
5. What is the difference between CGM & insulin pumps?
Continuous glucose monitoring collects information on your blood glucose levels. This information can be used for proper insulin dosing through your insulin pump. CGM and insulin pumps can be used separately (a person can use just one or the other) or together.
