Continuous Glucose Monitoring (CGM) Therapy

Did you know that you can monitor your blood sugar level every minute of the day and night without pricking your fingers? You can do that when you use Continuous Glucose Monitoring (CGM). Ana Silva, DO, at Endocrine Help, offers CGM devices to patients with pre-diabetes, diabetes, insulin resistance and many other conditions in Florida. Dr. Ana teaches them how to use it, how to use this technology to make lifestyle changes, and provides ongoing diabetes management. To learn more about CGM, schedule a telehealth appointment online.



What is continuous glucose monitoring (CGM)?

CGM is done through an advanced medical device that does exactly what its name describes: It continuously measures your blood sugar and sends the information wirelessly to a monitor or your smartphone.
Anytime you need to check your blood sugar, you only need to look at the monitor. Day or night, you can feel confident that your blood sugar is well-controlled without numerous finger sticks.

Who needs CGM?

CGM is primarily used by children and adults who are diagnosed with Type 1 diabetes. However, the device is increasingly used to give real-time feedback about blood sugar and to support behavior changes in patients with prediabetes and Type 2 diabetes.

Dr. Silva may recommend CGM if you:

  • Are on intensive insulin therapy

  • Don’t recognize the signs or symptoms of low blood sugar

  • Have frequent episodes of hypoglycemia

  • Often have low or high blood sugar

  • If you struggle to control your diabetes

Patients who need to maintain tight blood sugar control can wear the CGM all the time. Others may only need the support for a short time as Dr. Silva adjusts their diabetes care plan.

How does CGM work?

Dr. Ana recommends one of three CGM devices: Dexcom G6, FreeStyle Libre, or Medtronic. All three use a sensor that’s placed on your skin, typically on your tummy or arm. Placing a sensor is easy to do at home after training and is virtually painless. The sensor detects and measures glucose levels in the fluids surrounding the cells.

Some CGMs transmit your blood sugar levels wirelessly to a monitor, while others collect the information when you swipe the monitor over the sensor. The monitor may be an integral part of an insulin pump, or it could be a separate device that you carry in a purse or pocket. 

You can also get a CGM that sends the information to your smartphone or tablet, allowing you to use your personal device as a monitor.

Whichever type of monitor you use, a graphic displayed on the screen shows whether your glucose levels are rising or falling, and how quickly the levels are changing. With this immediate, real-time information you can quickly take action to restore your targeted glucose level.

What special features can CGM have?

Most CGMs include features such as sounding an alert when your blood sugar drops below or rises above your targeted range. You can also share your information with family or friends, so they get the same alerts and can connect with you to ensure you’re taking action to stabilize your blood sugar.

The data collected also shows patterns in blood sugar fluctuations that can help you better control your diabetes. This information is securely transmitted to Dr.Ana so she can review them with you and make precise recommendations to improve your diabetes control.  Some CGMs can be integrated with insulin pumps, automatically tuning your insulin dose based on the real-time CGM measurements.

If you suffer from insulin resistance, pre-diabetes, diabetes, Dr. Ana offers the help you need through telehealth services, and direct texting options are available. You can easily schedule an appointment at your convenience using the online booking tool.
