Let’s clear the air on a common misconception: Continuous Glucose Monitors are not just for people who use insulin. For years, this belief has kept a powerful tool out of the hands of those who could benefit most. The truth is, a cgm for non-insulin diabetes is a game-changer for anyone looking to proactively manage their metabolic health. It provides the real-time feedback you need to understand how your lifestyle choices directly impact your body. This isn't about reacting to a high A1c every few months; it's about making informed decisions every single day that can lead to better energy, stable moods, and long-term health.

Key Takeaways

• See the immediate impact of your choices: A CGM shows you exactly how your body responds to specific foods, workouts, and even stress in real time, taking the guesswork out of your health decisions.

• Go beyond reactive A1c checks: You don't need to be on insulin to benefit. A CGM empowers you to make small, daily adjustments that improve your health long before your next lab test, shifting you from a reactive to a proactive mindset.

• Turn data into a clear action plan: Raw data can be overwhelming; the real value comes from working with a care team to interpret your unique patterns and create a simple, personalized strategy for lasting change.

What is a Continuous Glucose Monitor (CGM)?

If you've ever felt like you're just guessing about your blood sugar, you're not alone. Traditional finger pricks give you a single number at a single moment, but what happens in all the hours between those checks? That’s where a Continuous Glucose Monitor, or CGM, completely changes the game. Think of it as watching the full movie of your glucose levels, rather than just looking at a few random snapshots.

A Continuous Glucose Monitoring (CGM) device is a small, wearable sensor that you place just under your skin. It stays there for several days, quietly tracking your glucose levels around the clock. This means you get a constant stream of data, showing you exactly how your body responds to the food you eat, the exercise you do, and even how well you sleep. Instead of just seeing a few high or low numbers, you can see the full picture: the peaks, the valleys, and all the subtle shifts in between. This isn't just about collecting data; it's about finally understanding the "why" behind your numbers. Why did you feel sluggish after lunch? Why did you wake up with more energy after a certain dinner? The CGM provides the clues. This continuous insight is the foundation for making meaningful, personalized adjustments to your lifestyle, empowering you to take control of your health in a way that simply wasn't possible before. It’s a tool that helps you become the expert on your own body.

How Does a CGM Actually Work?

It might sound complex, but the technology behind a CGM is surprisingly straightforward and designed to be unobtrusive. The sensor has a tiny, flexible filament, about the thickness of a human hair, that sits in the interstitial fluid just beneath your skin. This is the fluid that surrounds your cells, and its glucose level is closely related to your blood glucose level. The sensor measures the glucose in this fluid every few minutes, 24/7. From there, a small transmitter attached to the sensor wirelessly sends glucose readings to a display device, which can be your smartphone or a dedicated reader. You can see your current glucose level and trends at a glance, without a single finger prick.

CGM vs. Finger Pricks: What’s the Difference?

For years, finger pricks were the standard for checking glucose, but they only offer a brief glimpse into your body's activity. It’s like trying to understand a whole movie by looking at a few random screenshots; you miss the plot and the context. A CGM, on the other hand, provides the full story. By continuously measuring your glucose, it reveals important trends and patterns that isolated finger pricks can't possibly capture. You can see how your levels rise after a meal, dip during exercise, or change overnight. This rich data allows you to make much more informed decisions. It's important to know that a CGM doesn't always completely replace finger pricks. Your care team might still recommend an occasional finger-prick test to calibrate your device or to confirm a reading if your symptoms don't match what the CGM is showing.

Why Use a CGM If You're Not on Insulin?

It’s a common question: If I’m not taking insulin, why would I need to track my glucose all the time? The answer is simple: knowledge is power. A continuous glucose monitor (CGM) gives you a direct line of sight into how your body responds to your daily life, not just your meals. It’s about moving from a reactive state, where you only find out your A1c every few months, to a proactive one, where you can make small, effective changes every single day.

Think of it as a personalized roadmap to your metabolic health. Instead of following generic advice, you get to see exactly what a stressful workday, a poor night's sleep, or a brisk walk does to your glucose levels in real time. This data is the key to understanding your body’s unique patterns and making sustainable lifestyle adjustments that truly work for you. It’s not about restriction; it’s about discovery. By seeing the immediate cause and effect of your choices, you can finally build habits that lead to long-term health and even diabetes reversal.

See How Stress, Sleep, and Exercise Affect Your Glucose

Your blood sugar isn't just about the food you eat. It’s a sensitive indicator of your overall well-being, reacting to everything from a high-intensity workout to a looming deadline at work. A CGM helps you see these connections clearly. You might notice a glucose spike after a tense meeting or see how a restless night impacts your numbers the entire next day. These are insights you simply can't get from a few finger pricks. Understanding these non-food triggers is a huge step toward managing your health holistically. There are many misconceptions about wearing a CGM, but its ability to reveal these patterns is one of its most powerful features.

Connect the Dots Between Your Lifestyle and Your Numbers

Have you ever wondered if that "healthy" smoothie is actually working for you? A CGM takes the guesswork out of your diet and daily routines. It provides real-time data that shows you the immediate glucose response to a specific meal, a walk, or even your morning coffee. This instant feedback loop allows you to connect the dots between your actions and your body's reaction. You can see which foods keep your glucose stable and which ones send it soaring, empowering you to build a personalized nutrition plan based on your own biology, not a generic template. This is how you start making changes that stick.

Make Smarter, Data-Driven Health Choices

Living with type 2 diabetes can often feel like you're navigating without a map. A CGM changes that by putting concrete data in your hands. Instead of guessing what might work, you can make confident, informed decisions about your health every day. Studies show that using a CGM helps people with non-insulin-treated type 2 diabetes get better control of their blood sugar. When you see how your choices directly influence your glucose levels, you're more motivated to stick with positive habits. It transforms health management from a chore into an engaging, data-driven process where you are firmly in the driver's seat.

What Are the Real Benefits of Using a CGM?

Beyond just seeing your numbers, a continuous glucose monitor gives you the power to change them. It’s about turning a constant stream of data into real, tangible health improvements that you can see and feel every day. When you understand the immediate impact of your choices, you move from guessing what works to knowing what works. This isn't just about tracking; it's about taking informed, decisive action. It’s the difference between following a generic plan and creating one that’s perfectly tailored to your body’s unique responses. Let's look at what that actually means for you and your health goals.

Gain Better Control and Lower Your A1c

Your A1c is a key indicator of your average blood sugar over the past few months. Lowering it is a major goal in managing type 2 diabetes, but it can feel like a slow, abstract process. A CGM makes it concrete. By seeing your glucose levels in real time, you can make small, daily adjustments to your meals, activity, and stress levels that add up to big results. Research shows that this constant feedback loop works. Using a CGM leads to a significant drop in HbA1c, helping you gain a level of control that’s difficult to achieve with finger pricks alone.

Spend More Time in Your Ideal Glucose Range

Feeling your best often comes down to stability. The constant ups and downs of glucose spikes and crashes can leave you feeling tired, foggy, and irritable. The goal is to spend more "Time in Range" (TIR), which is the amount of time your glucose levels stay within a healthy target zone. A CGM is the best tool for this job. One study found that the time people spent with their blood sugar in a healthy range (between 70-180 mg/dL) increased from about 42% to 59% after a year of use. More time in range means more energy, better mood, and a healthier body overall.

Build Confidence in Managing Your Health

Living with type 2 diabetes can come with a lot of uncertainty. You might constantly second-guess your food choices or wonder if a workout was effective. A CGM replaces that doubt with data-driven confidence. When you see that a walk after dinner stabilized your glucose, or that a certain breakfast kept you steady all morning, you build trust in your own ability to manage your health. This isn't about perfection; it's about learning and adapting. Consistent CGM use has proven to be a valuable tool for managing type 2 diabetes because it empowers you to become the expert on your own body.

Spot Potential Issues Before They Become Problems

One of the most powerful features of a CGM is its ability to act as an early warning system. Instead of finding out your glucose is high hours after a meal, you can get an alert as it starts to rise, giving you time to intervene. These alerts for high or low glucose allow for proactive management. Maybe you need to take a short walk, drink some water, or simply note that a particular food combination didn't work for you. This shifts you from a reactive to a proactive mindset, helping you gently steer your glucose back into range before it becomes a bigger issue.

What Are Your CGM Options?

Once you’ve decided to try a CGM, the next step is figuring out which one is right for you. The good news is that you have more options than ever before. From prescription devices integrated into a full health program to new over-the-counter sensors, there’s a CGM that can fit your lifestyle and goals. Let’s walk through the main choices so you can feel confident in your decision.

How Heald Personalizes Your CGM Experience

A CGM is a powerful tool, but it’s most effective when you have support to translate its data into action. At Heald, we don’t just hand you a device and wish you luck. Your CGM is fully integrated into your personalized program. Our expert care team, including nutritionists and behavioral coaches, helps you understand what your numbers mean in the context of your unique life. We use this real-time feedback to fine-tune your plan, helping you make lasting improvements in blood sugar control. It’s about turning data points into sustainable habits that lead to real reversal.

Exploring Over-the-Counter CGMs

The world of glucose monitoring is changing fast, and one of the biggest shifts is the arrival of over-the-counter (OTC) CGMs. Devices like the Stelo wearable glucose biosensor are now available without a prescription, making this technology more accessible than ever. This is great news if you want to start tracking your glucose to understand your metabolic health without needing to schedule a doctor's visit first. It puts the power directly in your hands, allowing you to be proactive about your health on your own terms and timeline.

A Look at Popular Brands: FreeStyle Libre & Dexcom

As you explore CGMs, you’ll likely come across two major names: FreeStyle Libre and Dexcom. The FreeStyle Libre 3 is known for being the world's smallest and thinnest sensor, which you wear for 15 days while getting data sent straight to a smartphone app. The Dexcom G7 is another popular choice, praised for its high accuracy and ease of use in managing type 2 diabetes. Both are excellent tools, and the best one for you often comes down to personal preference, cost, and what your care team recommends.

Real-Time vs. Scanned: Which Is Right for You?

CGMs generally fall into two categories: real-time and intermittently scanned (also called "flash"). Real-time CGMs give alerts automatically, sending data to your phone or a reader around the clock. They’ll sound an alarm if your glucose gets too high or too low, which helps you act quickly. Intermittently scanned CGMs require you to manually scan the sensor with your phone to get a reading. While they don’t offer proactive alerts, they can be a more affordable option. Choosing between them depends on whether you prefer automatic, constant feedback or a more on-demand approach to checking your numbers.

What Does the Science Say About CGMs?

It’s one thing to hear stories about how a CGM can change your life, but it’s another to see the hard data. If you’re like me, you want to know what the research says before you commit to a new health tool. The good news is that the scientific community has been paying close attention to CGMs, and the findings are incredibly promising, especially for people with type 2 diabetes who aren't on insulin.

For years, the conversation around CGMs was almost exclusively focused on insulin-dependent diabetes. But that’s changing. A growing body of evidence shows that when people with non-insulin-treated type 2 diabetes use a CGM, they see real, measurable improvements in their health. Researchers are finding that the real-time feedback from a CGM empowers people to make more effective lifestyle choices, leading to better blood sugar control and a deeper understanding of their own bodies. It’s about moving from guessing to knowing, and the science backs it up.

The Proof: Lower A1c and Better Health Outcomes

The A1c test is one of the most important numbers in diabetes management, giving you a big-picture look at your average blood sugar over the past two to three months. Lowering it is a key goal, and this is where CGMs truly shine. Multiple studies have confirmed that using a CGM helps people with type 2 diabetes achieve better glucose control. A systematic review and meta-analysis found that CGM use leads to a significant reduction in HbA1c levels. This isn't just a minor tweak; it's a meaningful shift that points to better long-term health and a reduced risk of complications.

Beyond the Numbers: Long-Term Health Wins

While a lower A1c is a fantastic result, the day-to-day benefits are just as important. Think about how much better you feel when your glucose levels are stable. Research shows that long-term CGM use helps adults with type 2 diabetes maintain better blood sugar control over time. Specifically, people who use a CGM spend more time within their ideal glucose range and less time dealing with the energy drains and health risks of hyperglycemia (high blood sugar). This consistency is key to feeling your best each day and building sustainable habits that protect your health for years to come.

Is It Worth It? The Value of Using a CGM

So, is a CGM a worthwhile investment for your health? The evidence points to a clear yes. The data doesn't just show better numbers; it also shows an improved patient experience. When you have clear, immediate feedback on how your food, exercise, and stress levels affect you, you’re no longer flying blind. You can make confident, informed decisions. This is why a critical review of reported trials concluded that the evidence strongly supports CGM use for individuals with type 2 diabetes, even if they don't require insulin. It’s a valuable tool that empowers you to take an active, effective role in managing your health.

Common CGM Myths, Busted

Continuous glucose monitors can feel like a big step, and it’s easy to get held back by outdated information or common misconceptions. If you’ve been curious about using a CGM but have heard things that made you pause, let’s clear the air. Understanding the truth behind the technology is the first step toward using it to take control of your health. Let's break down some of the most persistent myths about CGMs so you can make a decision based on facts, not fiction.

Myth: "CGMs Are Only for People on Insulin"

This is one of the most common and outdated beliefs about CGMs. While they are an essential tool for people who use insulin, their benefits extend far beyond that. In fact, a growing number of people with diabetes not using insulin are using CGMs to manage their health. Why? Because a CGM gives you a direct window into how your body responds to your daily choices. You can see in real-time how a specific meal, a walk after dinner, or a stressful meeting affects your glucose levels. This information is incredibly powerful for making lifestyle adjustments that can help you manage or even reverse type 2 diabetes without medication.

Myth: "CGMs Are Too Expensive or Not Covered"

It’s true that cost can be a barrier, but access to CGMs is improving all the time. The idea that they are completely unaffordable is quickly becoming a thing of the past. Many major insurance companies now cover CGMs, and more are expanding their coverage every year. Plus, you can often use funds from a Flexible Spending Account (FSA) or Health Savings Account (HSA) to pay for the device and sensors. Think of it as an investment. The data you get can help you prevent costly health complications down the road, making it a valuable part of your long-term wellness plan.

Myth: "The Technology Isn't Accurate Enough"

Some people worry that a CGM won’t be as accurate as a traditional finger-prick test. It’s important to understand that they measure glucose in two different ways. A blood glucose meter measures glucose directly from your blood, while a CGM measures it from the interstitial fluid just under your skin. While there can be a slight lag between the two readings, measuring glucose from interstitial fluid is a scientifically reliable method for monitoring. The real power of a CGM isn’t in a single reading, but in the trends and patterns it reveals 24/7. This continuous data gives you a much fuller picture of your health than a few finger pricks ever could.

How to Turn Your CGM Data into Action

A continuous glucose monitor is more than just a piece of technology; it’s a storyteller. It tells you the story of how your body responds to every meal, workout, stressful meeting, and night of sleep. But having the data is only the first step. The real transformation happens when you learn how to translate those numbers into meaningful, sustainable lifestyle changes. This is where you move from passively tracking to actively taking control of your health.

Instead of guessing what works, you get a clear, personalized roadmap. You can see the immediate impact of swapping your usual breakfast for a protein-rich option or discover how a 15-minute walk after dinner can stabilize your evening glucose levels. This process isn’t about perfection or chasing a flat line. It’s about understanding your body’s unique language and using that knowledge to make smarter choices, one day at a time. With the right approach, your CGM data becomes your most powerful tool for building lasting habits.

Learn to Read Your Body’s Unique Patterns

Your CGM data is a rich source of information, but it can feel overwhelming at first. The key is to look for patterns, not just individual numbers. Your body has a unique rhythm, and your CGM helps you see it clearly. Start by noticing what happens to your glucose after you eat certain foods, when you exercise, or even after a poor night's sleep. Over time, you’ll begin to visualize glycemic patterns that are specific to you. For example, you might find that your glucose is more sensitive in the morning or that a stressful workday causes a bigger spike than a slice of cake. At Heald, our care team helps you interpret these trends, turning what looks like a random series of dots into a clear picture of your metabolic health.

Set Personalized Goals and Alerts

Once you start understanding your patterns, you can use your CGM to set personalized goals. This isn't about adhering to a generic "good" number; it's about defining what a successful range looks like for your body and your life. Most CGM systems allow you to set custom alerts for high and low glucose levels. Using these alerts can lead to lasting improvements in blood sugar control, especially if you set the high alert to a proactive level that nudges you before your glucose goes too far out of range. Think of these alerts not as alarms, but as gentle reminders. They’re your personal health assistant, tapping you on the shoulder to suggest a short walk or a glass of water, helping you stay on track with your goals.

Adjust Your Diet and Activity in Real-Time

This is where the magic happens. Your CGM gives you the power to make immediate, informed decisions. You can see in near real-time how your body responds to foods, exercise, and stress. Did your glucose spike after that bowl of pasta? Next time, you could try adding a source of protein and fiber or going for a walk right after your meal to see how it changes the curve. This instant feedback loop transforms your health journey into an experiment where you are the lead scientist. You’re no longer following a rigid diet plan; you’re learning to work with your body, making small, effective adjustments that add up to significant, long-term results.

Pair Your CGM with These Lifestyle Changes

A continuous glucose monitor is an incredible tool, but it’s not a passive fix. Think of it as your personal health detective, giving you clues about what’s happening inside your body. The real magic happens when you take those clues and turn them into action. Pairing your CGM data with intentional lifestyle adjustments is how you create lasting, meaningful change. It’s about moving from simply knowing your numbers to understanding the story they tell about your daily choices.

This is where you shift from being a passenger to being the driver of your health journey. When you see the direct impact of a meal, a workout, or a stressful day, you’re empowered to make small, effective changes. Instead of following a generic plan, you can build a routine that’s tailored specifically to your body’s unique responses. This combination of real-time data and responsive action is the foundation for reversing type 2 diabetes and building a healthier future. It's the difference between being told what to do and discovering for yourself what truly works. This process of discovery and adjustment is at the heart of sustainable health, helping you build habits that stick because you've seen the proof on your own screen.

Fine-Tune Your Diet with Instant Feedback

Ever eat something you thought was healthy, only to feel sluggish and tired an hour later? A CGM takes the guesswork out of nutrition by showing you exactly how your body responds to different foods in real time. That bowl of oatmeal or "healthy" smoothie might be causing a bigger glucose spike than you realize. This instant feedback loop is a powerful tool for learning. You can see which carbohydrate sources work best for you, how protein and fat help stabilize your glucose, and the ideal timing for your meals. It allows you to understand your metabolic health on a much deeper level, making it easier to build a sustainable eating plan that you actually enjoy.

Optimize Your Workouts and Manage Stress

Food isn’t the only thing that affects your glucose levels. A stressful work meeting, a poor night's sleep, or even a very intense workout can cause your blood sugar to rise. A CGM helps you connect these dots. You might notice that a morning walk keeps your glucose stable all day, while a high-intensity session causes a temporary spike. This doesn't mean intense exercise is bad; it just gives you information to plan around it, perhaps by having a protein-rich snack afterward. Similarly, seeing a glucose rise during a stressful part of your day can be the nudge you need to incorporate stress-management techniques, like a few minutes of deep breathing or a quick walk outside.

Improve Your Sleep and Build Healthier Habits

Your health doesn’t stop when you go to sleep, and neither does your CGM. By tracking your glucose levels overnight, you can uncover hidden patterns that impact how you feel the next day. You might discover that a late-night snack is disrupting your sleep and your morning glucose, or that getting a solid eight hours keeps your levels beautifully stable. This 24/7 data provides a much richer, more accurate picture of your health than a single lab test every few months. It helps you see how all your habits are interconnected, empowering you to build a holistic routine where better sleep leads to better food choices, which in turn gives you more energy for activity.

How to Make a CGM Part of Your Daily Life

Wearing a continuous glucose monitor is the first step. The real transformation happens when you learn how to weave its insights into your daily rhythm. Think of it less as a medical device and more as a personal health coach that gives you a constant, quiet stream of feedback. Integrating it into your life isn’t about obsessing over every number; it’s about building a new awareness of how your body responds to your choices.

The goal is to turn data into sustainable habits. Instead of guessing which foods work for you or how a stressful meeting impacts your body, you’ll have clear, immediate answers. This process helps you move from reacting to your health to proactively managing it. Making a CGM a true part of your life comes down to three key things: working with a team that can help you make sense of the data, creating a plan that isn't overwhelming, and finding the right motivation to stick with it for good. When these pieces fall into place, the CGM becomes a powerful tool for lasting change.

Partner with Your Care Team for the Best Results

You don’t have to become a data scientist overnight. A CGM provides a wealth of information, but the real value comes from interpreting it with an expert. Your care team, including doctors, nutritionists, and health coaches, can help you see the story your numbers are telling. They can distinguish a normal fluctuation from a pattern that needs attention and help you connect the dots between your glucose levels and your lifestyle.

At Heald, our team works with you to translate your CGM data into a personalized strategy. Research shows that long-term CGM use can lead to significant and lasting improvements in blood sugar control for adults with type 2 diabetes, and that success is amplified when you have professional guidance. It’s a partnership designed to help you understand your body on a deeper level.

Create a Simple, Actionable Plan

Getting flooded with data can feel just as confusing as having no data at all. The key is to focus on what matters most. Instead of trying to analyze every single data point, work with your care team to create a simple, actionable plan. This means having a structured approach to interpreting CGM data that feels manageable and leads to clear next steps.

Your plan might start by focusing on one thing, like understanding your post-meal glucose spikes. You can experiment with different foods or try a short walk after eating and see the immediate impact. The goal is to create simple "if-then" strategies. For example, "If I see a spike after breakfast, then tomorrow I'll try adding more protein." This turns overwhelming data into a series of small, achievable experiments that build powerful new habits over time.

Stay Motivated for the Long Haul

Let’s be honest: motivation isn't always easy to maintain. What makes a CGM so effective is that it provides instant feedback that reinforces positive choices. When you see your glucose line stay steady after a healthy meal or a workout, it’s a powerful, tangible reward that a number on a scale can’t always provide. This immediate validation keeps you engaged and proves that your efforts are working.

This tool helps you understand the why behind your health, showing you how your daily actions can fix the underlying metabolic health issues that may have felt out of your control. Seeing this direct cause-and-effect relationship transforms health management from a chore into a fascinating process of discovery. It fuels your curiosity and empowers you to keep making choices that serve your body well.

Ready to Get Started with a CGM?

If you’re considering a Continuous Glucose Monitor, you’re on the right track to taking a more active role in your health. The idea of seeing your glucose levels in real time isn’t just interesting; it’s a powerful way to connect your daily choices to your body’s unique responses. This isn't about chasing perfect numbers. It's about gathering personal insights so you can make smarter, more confident decisions about your food, activity, and well-being.

The science confirms that this approach works. Research highlighted by the National Institutes of Health shows that CGMs are highly effective for people with non-insulin-treated Type 2 diabetes, helping them gain better glycemic control. It’s a tool that provides the immediate feedback needed to build healthier, more sustainable habits. With modern devices sending readings directly to your smartphone, it’s never been easier to stay informed.

But data is only one piece of the puzzle. A CGM is an incredible tool, but its true power is revealed when you have a plan and a team to help you turn those numbers into action. At Heald, we pair CGM technology with one-on-one support from our expert care team. We help you understand what your data means for you and guide you in making small, consistent changes that lead to significant, long-term results. If you’re ready to move beyond guessing and start making data-driven progress, we’re here to help you get started.

Frequently Asked Questions

Does wearing a CGM hurt? This is easily the most common question, and the answer is, for the vast majority of people, no. The sensor is applied with a simple applicator, and the part that goes under your skin is a tiny, flexible filament about the thickness of a human hair. Most people feel a slight pressure during application and then completely forget it’s there as they go about their day, from working out to showering and sleeping.

Is a CGM really necessary if I'm not on insulin? Think of it less as a medical necessity and more as a powerful tool for discovery. If you're not on insulin, your goal is likely to manage your health through lifestyle. A CGM gives you the direct feedback you need to do that effectively. It shows you exactly how your body responds to your meals, your stress levels, and your sleep, empowering you to make personalized changes that you can actually see working in real time.

I'm worried about getting overwhelmed by all the data. How do I manage that? That's a completely valid concern. The goal isn't to obsess over every single number but to learn the story your body is telling over time. The best way to manage this is by focusing on one thing at a time, like your response to breakfast, and working with a care team. A coach or nutritionist can help you cut through the noise, identify the most important patterns, and turn those insights into a simple, actionable plan.

How accurate is a CGM compared to a finger-prick test? While both are useful, they measure glucose in slightly different ways. A finger-prick test measures glucose directly from your blood, while a CGM measures it from the fluid just under your skin. There can be a small lag between the two, but modern CGMs are highly reliable. Their real strength isn't in one single reading, but in showing you the trends and patterns throughout the day, which is something a finger prick can't do.

Are CGMs expensive, and will my insurance cover it? Cost and coverage are definitely important factors, but access to CGMs is getting better all the time. Many insurance plans now cover CGMs for people with type 2 diabetes, even those not on insulin. It's always best to check directly with your provider to understand your specific benefits. You can also often use funds from an FSA or HSA, which makes it a more manageable investment in your long-term health.
