Dexcom ONE+:
A CGM for Type 2 Diabetes
Monitoring your blood sugar levels is an important part of looking after your overall health when living with type 2 diabetes. Continuous Glucose Monitoring (CGM) is one of the ways to see where your glucose levels are at, empowering you to make choices that help you manage your glucose and lower your HbA1C over time.1,2
CGM devices, like the Dexcom ONE+ CGM System, are a good option for those living with type 2 diabetes (T2D) who want to check their glucose levels without routine finger pricks*. It allows you to better understand what impacts your glucose so you can confidently take control of your diabetes management. CGM is also a helpful tool for people who might need extra support with their glucose management, such as children, pregnant women, and those who are hypo unaware.
Why is CGM More Common for People with Type 1 Diabetes?
Unlike T2D, people living with type 1 diabetes (T1D) are dependent on insulin because their body isn’t able to make its own. They must, therefore, carefully monitor their blood sugar levels to determine how much insulin they need and administer that insulin through a pump, a pen, or injections. CGM devices can make this process easier, more automated, and more convenient.
For these reasons, the National Institute for Health and Care Excellence (NICE) guidelines suggest that all people living with T1D be offered CGM technology to help them manage diabetes.3
Can I Use CGM For Type 2 Diabetes?
Although many people with T2D don’t need to be on insulin therapy, continuous glucose monitoring can still be a great option for those who want to keep a closer eye on their glucose levels or need extra support with everyday diabetes management, such as those living with disabilities or elderly people with reduced independence. Everyone’s needs are unique, so it’s important to discuss with your healthcare provider if adding CGM to your diabetes management is right for you.
The major international diabetes organisations recommend the use of CGM for all adults with diabetes (T1D and T2D) on multiple daily injections/CSII and basal insulin only with the highest level of evidence (ADA, AACE, EASD consensus guideline).4-6
Under some conditions, NICE also recommends CGM for children and young people living with T2D who may or may not require insulin therapy,7 as well as adults living with T2D who need multiple daily insulin injections.8 Some of these conditions include:
- Unable to engage in capillary blood glucose monitoring (CBGM) due to their mental health or if they’re living with a learning disability or cognitive impairment.
- Need to take glucose readings at least eight times a day.
- Experience frequent, severe hypoglycaemia.
- Adults who are regularly unable to recognise the symptoms of low blood sugar or hypoglycaemia (a condition known as hypo unawareness).9
CGM is also a recommended option for people living with T2D on insulin therapy who are pregnant. NICE states that CGM should be offered to pregnant women if they’re experiencing frequent hypoglycaemia or have challenges keeping glucose levels stable.10
How People Living With T2D Can Benefit From CGM
CGM might be especially useful for certain people depending on their needs and concerns. However, anyone living with diabetes can benefit from the added convenience and peace of mind that CGM provides.
1. Identify Glucose Levels Without Relying On Symptoms
Some people living with diabetes may struggle to identify symptoms of low or high glucose, such as children and older adults. About 10 to 15 percent of people with T2D also experience hypoglycaemia unawareness.9
Dexcom ONE+ allows you to set custom alerts that notify you whenever your glucose is higher or lower than your target glucose range—generally between 4-7 mmol/L before meals and under 8.5 mmol/L two hours after meals.11 This helps you stay aware of your glucose levels and make changes to avoid highs or lows—without having to count on your symptoms to warn you.
2. Make Proactive Treatment Decisions
When you’re keeping an eye on your glucose levels using a blood glucose monitor (BGM), you can only measure your blood glucose level the moment you prick your finger* and take a reading. This can make it difficult to figure out if you should prepare to treat a hypo or if something you’ve just eaten is about to cause a spike in your glucose levels. People who are hypo unaware or experience hypoglycaemia at night may find it hard to know when and how best to treat lows.
CGM systems can make it easier to see where your glucose levels are at and where they’re headed, so that you can take steps to manage them. Dexcom ONE+ sends glucose readings to your compatible smartphone† up to every five minutes, giving you insight into what’s going on in your body much faster than performing a finger prick‡ and waiting for the readings with a BGM. This—along with custom high and low alerts12—allows you to take action ahead of time and, in the process, improve your time in range (TIR), typically defined as between 3.9 mmol/L and 10 mmol/L .§,2,13-15
It's important to note that everyone’s recommended TIR thresholds may not be exactly the same, so you’ll need to determine with your diabetes care team what these are for you.
3. Improve Your Diabetes Management Habits
It’s not always easy to pinpoint what’s making your glucose levels go up and down throughout the day or what has the greatest impact on your HbA1C over time. CGM can help you get a better idea of what may be causing highs and lows, giving you the chance to make adjustments to your diabetes management plan based on hard data.
With Dexcom ONE+, you can see the impact of lifestyle decisions, like going for a brisk walk or having a snack, on your glucose levels in real time. You can also view up to 24 hours of glucose readings at a glance on your compatible smartphone.† Dexcom ONE+ can be used with Dexcom Clarity,|| an app that allows you to view glucose data over days, weeks, months, and even years—and share it with your healthcare provider.¶ This allows you to spot patterns in your glucose levels, so you can figure out how your routines affect your glucose management.
4. Remotely Monitor Your Loved One’s Glucose Levels
Dexcom CGM enables caregivers of people living with diabetes the ability to remotely monitor a person’s glucose levels throughout the day and night—whether they’re in the same room or across the country. While T2D diabetes is less common in younger individuals, remote monitoring is especially helpful for kids and teens who are at school or out with friends. It also works well for elderly people, adults who depend on others for care and those or those who are hypo unaware.9
The Dexcom Follow app# allows you to share your Dexcom ONE+ data with up to 10 Followers. These people can receive your glucose data wherever they have a wifi connection, even if they are miles away. Data shows that having one or more Followers on the Dexcom Follow app# correlates with more time-in-range and less hypoglycaemic events.**,16-18
5. Support Your Health During Pregnancy
Keeping your glucose levels stable throughout pregnancy is critical for the health of you and your child, especially if you have diabetes.19 While some people are already living with diabetes when they enter pregnancy, others can develop it for the first time during pregnancy—also known as gestational diabetes.
CGM systems like Dexcom ONE+ can give you a direct view into your glucose levels, helping you maintain stable glucose levels throughout pregnancy. It can also relieve some of the stress of glucose management because you don’t need to remember to perform BGM readings or worry about pricking your fingers throughout the day,* freeing you up to focus on taking care of your family and yourself.
Discover How CGM Can Improve Life With T2D
Managing T2D is about maintaining your health and ensuring that you have the resources you need to thrive. Dexcom ONE+ can help you understand your glucose levels and take proactive action to keep them in range, so you can feel your best more often. Talk to your healthcare provider about whether Dexcom ONE+ could help you support your diabetes management.
