What is a CGM?
A CGM is a small, wearable device that measures your blood glucose levels throughout the day and night. It consists of a sensor that is inserted under your skin and a transmitter that sends your glucose readings to a receiver or your smartphone. CGMs can be very helpful for people with diabetes, as they can help them to manage their blood sugar levels and prevent complications. However, CGMs can also be beneficial for people without diabetes who want to track their blood glucose levels for various reasons.
Why Would Someone Without Diabetes Want a CGM?
There are several reasons why someone without diabetes might want to get a CGM. Some of the most common reasons include:
- To track their blood sugar levels for fitness or weight loss. CGMs can help people to track their blood sugar levels in response to different foods and activities. This information can be helpful for people who are trying to lose weight or improve their fitness.
- To monitor their blood sugar levels during pregnancy. CGMs can help pregnant women to monitor their blood sugar levels and prevent gestational diabetes.
- To manage other health conditions. CGMs can be helpful for people with certain health conditions, such as Polycystic Ovary Syndrome (PCOS) or prediabetes.
How to Talk to Your Doctor About Getting a CGM
If you’re interested in getting a CGM, the first step is to talk to your doctor. Your doctor will be able to assess whether a CGM is right for you and help you to get started.
Here are some tips for talking to your doctor about getting a CGM:
- Be prepared to answer questions about your health history. Your doctor will want to know about your overall health, including any medical conditions you have, medications you’re taking, and lifestyle factors.
- Explain why you want a CGM. Let your doctor know why you’re interested in getting a CGM and what you hope to gain from it.
- Be open to feedback. Your doctor may have concerns about you getting a CGM. Be open to listening to their feedback and discussing alternative options.
What to Expect During the CGM Process
If your doctor decides that a CGM is right for you, they will prescribe one for you and give you instructions on how to use it. You can expect to wear the CGM for 10-14 days. During this time, the CGM will measure your blood glucose levels and send the data to a receiver or your smartphone.
You will need to check your CGM readings regularly and record them in a logbook. You will also need to calibrate the CGM every few days. Your doctor will provide you with specific instructions on how to do this.
Different Types of CGMs
There are several different types of CGMs available. The type of CGM that is best for you will depend on your individual needs and preferences.
Here are some of the different types of CGMs available:
- Real-time CGMs. Real-time CGMs send your blood glucose readings to a receiver or your smartphone every few minutes. This allows you to see your blood sugar levels in real time and make adjustments to your diabetes management plan accordingly.
- Intermittent CGMs. Intermittent CGMs take your blood glucose readings every 5-15 minutes. The data is stored on the CGM device and can be downloaded to a computer or smartphone later.
- Patch CGMs. Patch CGMs are small, adhesive patches that are worn on the skin. They measure your blood glucose levels and send the data to a receiver or your smartphone.
