What Are The Advantages Of Using Cgm To Manage Diabetes

Continuous Glucose Monitor Blood Sugar App

Using a CGM device can make it easier to manage Type 1 or Type 2 diabetes. Some people use CGM for a week to understand their blood sugar patterns. Most use CGM long-term.

A CGM device can:

  • Show you a bigger picture of how diabetes affects you: CGM measures glucose levels every few minutes. That data shows a more complete picture of how your blood sugar levels change over time. This information can help you and your provider better understand how things like food, activity, stress and illness impact your blood sugar levels.
  • Lead to more personalized care: CGM doesnt give the whole story of all the ways diabetes affects you. It tells you when glucose goes up or down, not why. But your provider can download CGM data from your device and review it for patterns and trends. They can then personalize your care based on what they learn.
  • Alert you to highs and lows: Most CGM devices send an alert when your glucose levels rise or fall a certain amount. With this information, you can make changes quickly. You may be able to treat or prevent highs or lows before they turn into a big problem.
  • Reduce how many fingerstick checks you need to do: CGM significantly reduces how many fingerstick tests youll need to do each day.

How Do I Get A Cgm

As with most medical technology, you need a prescription to get a CGM. Your doctor can write a prescription for any of the above CGM devices.

But getting a prescription for a CGM is often not as simple as just walking into your doctors office and asking for one. Instead, youll likely need a prior authorization to get a CGM through your health insurance. A PA is form/process that your doctor has to go through to prove medical necessity to obtain approval from your insurance plan to cover the costs associated with the prescribed treatment .

At this point, most major insurers require a PA before extending coverage for CGM. Heres how to go about securing a PA, according to JDRF, a leading T1D research and support organization:

  • Check your insurance plans policy documents and formulary to see if any of your treatments require a PA. You may find these on the plans website. If you have Medicare coverage, check the Medicare & Youhandbook for more information.
  • If a PA is needed, locate your insurance providers process for submitting and obtain any required forms. This information is typically found on the plans website, or you may call the member services number found on the back of your insurance card.
  • Your doctors office is responsible for submitting PAs, so it will be important to work with your doctor or the staff member in the doctors office designated to handle the paperwork.
  • If the request is denied, you should plan to appeal the decision.

    Best Uses For Intermittently Scanned Cgms

    Intermittently scanned continuous glucose monitors are most often recommended to:1,3

    • People with pre-diabetes
    • People newly diagnosed with type 2 diabetes who are learning how food and exercise affect their blood sugar levels
    • People who need to check their blood sugar several times a day, such as women with gestational diabetes
    • People with diabetes who want more data
    • People who want an alternative to standard glucose monitors and the sticks they require

    Intermittently scanned CGMs may provide plenty of data to help people with less serious forms of diabetes or pre-diabetes. Doctors most often use these devices to help patients see the direct connection between what they eat and what happens with their blood sugar.1,3

    Several CGM models are available in the United States. The devices are being used by more and more people with type 2 diabetes and prediabetes. All CGMs display your glucose numbers on a small screen that you keep on or near your body. They also send your data to a smartphone or computer.1,3

    Why Dexcom Diabetes Cgm Technology Is So Hot

    Continuous Glucose Monitoring: Evolving Evidence for Technology

    Weve come a long way in continuous glucose monitoring technology since it first hit the market over two decades ago, and San Diego-based Dexcom has been leading the way on innovation for most of that time.

    Since the launch of its initial 3-day sensor in 2006, Dexcom has helped shape how the U.S. Food and Drug Administration views this tech and forged new paths in providing more options for people to keep tabs on their blood sugars with a quick glance at a receiver, mobile app, or smartwatch.

    Dexcom is not the only CGM maker, and it wasnt the first Medtronic launched the first-ever CGM way back in 1999. But from its earliest model to the latest mobile connected device, Dexcom has cemented its spot as the most popular full-featured CGM available.

    Everything changes quickly in the diabetes device universe, so its important to keep tabs on what the company is up to. Heres a deep dive into what Dexcom is offering in 2020 and beyond, along with a bit of its rich history.

    All About Continuous Glucose Monitors For People With Diabetes

    Diabetes is a serious and growing problem in the United States. According to the Centers for Disease Control & Prevention, approximately 30.3 million Americans have diabetes, or about one in 10 people. Thats up from about 26 million people in 2010.

    Diabetes is a broad term for a group of conditions in which the bodys blood glucose levels to rise higher than normal, known as hyperglycemia. In many cases, it can be effectively managed through diet, exercise, medication, and blood glucose monitoring. As a supplement to the traditional finger-prick technology that people with diabetes have relied upon for many years to check their blood glucose levels, continuous glucose monitors offer a more convenient and less painful way for people to track their blood sugar and make positive lifestyle choices.

    What Are CGMs?

    In 1991, the U.S. Food & Drug Administration approved the first continuous glucose monitoring system for home use by adults with diabetes. This technology offers an alternative to taking blood from the fingertips, where the sample is taken from tiny blood vessels called capillaries. According to Alison Wharton, MPH, RDN, CDE, LD, a diabetes and nutrition education specialist with UAB Medicine, CGMs track blood sugar levels 24 hours per day by measuring the amount of glucose in interstitial fluid, which is the fluid that surrounds blood vessels.

    CGM can sound an alarm if the glucose level is changing rapidly. A hypo or the trend towards a hypo can trigger an alarm alerting the user or family/carer to treat immediately. Hypo refers to hypoglycaemia, when the blood glucose level has dropped too low. Alerts can prevent a hypo before it happens and is particularly useful overnight when parents and children are in separate rooms.

    The New World Of Glycemic Measures

    For many years, there has been a tremendous focus on A1C as the preferred, and sometimes only, measure of glycemia and diabetes management. However, as it represents an average glucose level over approximately three months, it does not directly provide insight into high glucose levels, low glucose levels, or variability in between, though each of these can be quite important. For example, two patients can have identical A1C values, but one may have little variability, with only modest and infrequent hyperglycemia and hypoglycemia, while a second may have high degrees of variation, frequently shifting between profound hyperglycemia and hypoglycemia, while achieving the same average glucose level as the first patient. This is where the added metrics available from CGM can be especially useful.

    Assessing and documenting these few metrics in a systematic way can help you maximize the insights that CGM can provide and streamline your efforts. Simply summarizing them in a note can be very helpful in this regard. Below are some suggested smart text or macros for two popular electronic health record systems that can be used or adapted to other systems.
