Glucose Monitoring in Olympia


What is a continuous glucose monitor?

A continuous glucose monitor (CGM) is a new, FDA-approved device that can automatically test blood sugar levels throughout the day. A CGM is a highly advanced way to test blood sugar levels, compared to the traditional fingerstick method. With a personal continuous glucose monitor, individuals with diabetes can measure their current glucose levels, as well as see whether their glucose is rising or falling and how quickly. The sensor can provide nearly 300 glucose readings per day.

A personal CGM works similarly to an insulin pump in that it is programmed to automatically perform a function throughout the day, making the management of diabetes much more convenient. In fact, if you use an insulin pump, you may be able to link it to your CGM system for continuous care.

Why is continuous glucose monitoring used?

Continuous glucose monitoring is done by patients with type 1 diabetes or type 2 diabetes in order to effectively monitor blood sugar levels. Diabetes is a chronic disease that prevents the body from properly producing or using insulin, the hormone needed to allow sugar (glucose) to enter cells to create energy. As a result, diabetic patients frequently experience irregular blood sugar levels that must be monitored and corrected by administering insulin. Leaving these blood sugar levels unchecked can lead to serious health complications, and can even be fatal. A continuous glucose monitor is an effective tool that helps diabetic patients monitor and maintain a safe and healthy blood sugar level.

What types of continuous glucose monitoring do you offer?

At Shawna Purcell, MD, Diabetes & Weight Loss Center in Olympia, Washington, we offer two different types of continuous glucose monitoring.

  • Personal CGM sensor – A personal continuous glucose monitor uses a tiny sensor placed under the skin of your stomach. The sensor measures the amount of glucose found in the fluid inside your body and then transmits this information to a computerized device for the patient to view.
  • Professional, in-office CGM sensor – A professional continuous glucose monitor is used by patients for a set number of days, after which the device is brought back to the doctor’s office for analysis. Once the data is reviewed, your doctor will go over the results with you. With professional CGM technology, doctors are able to get more insight into a patient’s glycemic profile, which can inform changes in therapy and lifestyle recommendations.

What are the advantages of using a continuous glucose monitor?

A continuous glucose monitor is an effective tool for monitoring blood sugar levels with less impact on your day-to-day routine. Some of the many benefits of using a CGM include:

  • Predictable and precise glucose monitoring
  • Provides you with more complete, real-time information about your blood sugar levels than fingerstick testing
  • Reduces need for fingerstick testing
  • Sensor can be placed in a discreet location
  • In-office CGM allows your doctor to make informed decisions about your diabetes treatment
