Dexcom’s continuous blood glucose monitoring system helps people living with diabetes track their blood sugar levels. People may find it more convenient than a traditional blood glucose monitor. The device connects to a person’s skin and provides continuous feedback to an app they can download onto their phone or tablet.

Brand overview and reputation

Founded in 1999,

Dexcom

released its first continuous glucose monitor (CGM) in 2006. The company has since made changes and upgrades to its designs. The Food and Drug Administration (FDA) and

Medicare

have approved the system and devices for various uses.

Dexcom claims their system can continuously provide updates and feedback about a person’s

blood sugar levels

. The person can then use the information to help manage their

diabetes

.

A person will require a prescription from their doctor.

Though Dexcom highlights positive reviews from several influencers’ on their website, all are “paid spokespersons.”

Trustpilot

ratings suggest the brand has a poor reputation. Out of over 30 reviews, they currently have a rating of 2 out of 5 stars. Reviewers mainly complain about poor customer service. Several also mention that the sensors are inaccurate and need constant calibration.

The

Better Business Bureau (BBB)

has a similar response from users. Out of over 140 reviews, they have a rating of 1.1 out of 5 stars. The reviews on BBB also mention poor service and inaccurate readings. The company has closed over 160 complaints in the past 3 years.

Products and services Dexcom offers

Dexcom’s CGM system pairs with companion apps to display data in real-time. Their products and services include:

G6 CGM System

The G6 CGM System is Dexcom’s primary product. It includes everything a person needs to monitor their blood sugar levels, including:

sensors

transmitters

applicator

a small device to display data

app connectivity

The G6 CGM system works by attaching a monitoring device to the skin. The system does not require a person to use finger sticks to get results. Instead, they can access their current levels anytime through the app.

CLARITY App

Dexcom also has an app for use on both Android and Apple devices. The Clarity Reporting software app displays live data and collects information to display in graphs.

The app also allows the person’s healthcare provider to log in to the individual’s accounts to look at the recorded data.

The app can show data such as:

glucose average

how often the person’s blood sugar remained in good or bad ranges

trends, such as when levels spike or dip

custom alerts

A person can download the CLARITY app on their phone through their app store or

Dexcom’s website here.

How to order

Dexcom no longer directly sells their G6 CGM System on their website. They are available at several brick-and-mortar pharmacies, such as Walgreens or CVS, or online at various retailers.

First-time buyers have to create a user account and supply a range of information, including insurance, medical, billing, and shipping details.

Diabetic Warehouse sells both combination transmitter and sensor packs. They also sell a G6 Receiver, which is what Medicare requires. A person can choose to order them separately or in a combination pack. At the time of publication, the combination pack costs around

$1,100

A person can order a pack of three sensors from Walmart for a little under

$300

. Each sensor can last up to 10 days.

Alternatives

Continuous blood glucose monitoring is a relatively new technology, but Dexcom is not the only company that offers it. Other devices include the

Freestyle Libre

, which the FDA has approved for people who are 18 and older. This device does not require calibration. The Freestyle Libre requires a prescription.

Another alternative is the

Medtronic Guardian Connect

. This device is approved for people aged 14–75 years but needs calibration 3 to 4 times a day. It also requires a prescription.

Some people may not want to use a CGM to manage their diabetes. If this is the case, a person can use a

blood glucose meter

. This device requires that a person pricks their finger to get a blood sample that they use to test their blood sugar levels.

Diabetes and health

A person living with diabetes needs to continually monitor their

blood glucose levels

to prevent blood sugar from going too high or too low. A CGM, like Dexcom, may help a person manage the condition.

In a

2017 review of studies

, researchers found that CGM systems can be safe and effective in monitoring blood sugar levels. The review notes that they can help with:

improving quality of glycemic control

reducing the risk of

hypoglycemia

permitting selection of lower target levels for average glucose and HbA1c

In other words, a CGM can help someone know when they need more

insulin

or when they need to eat more to help elevate their levels.

Diet and exercise can also play an essential role in keeping blood sugar at a safe level. The

National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

recommends a person base their diet on the following groups of food:

lean proteins

low fat dairy products

fresh vegetables and fruit

whole grains

A person should avoid foods that are high in salt, sugar, and saturated fat.

Exercise can play an important role in helping a person maintain a moderate weight and manage their blood sugar levels. Physical activity can lower a person’s overall blood sugar levels for up to

24 hours.

For people with a regular exercise routine, a CGM can show how the routine affects their sugar levels, allowing them to make diet adjustments as needed.

When to see a doctor

A person will need to talk to their doctor before ordering the Dexcom G6 CGM System. Medicare and insurance require a doctor’s prescription.

If a person experiences any unusual symptoms, they should talk with their doctor.

A person should contact Dexcom support if their symptoms and blood sugar readings do not match. This could be a sign the device is not working correctly.

Summary

Dexcom’s continuous blood sugar monitoring system allows people to follow their blood sugar trends. It also warns people of potentially dangerously high and low blood sugar levels.

The device is a convenient way for people to monitor their blood sugar, but it can be quite costly even with insurance. A person should talk with their doctor before ordering the device. A doctor can help them better determine if a CGM device like Dexcom’s can help.
