In March of the previous year, DexCom secured FDA clearance for its over-the-counter CGM, named Stelo. Shortly after, in June, Abbott followed suit, earning approval for two of its own over-the-counter CGM systems. This marked a significant turning point, making real-time glucose data available to anyone interested in tracking their metabolic response to diet, exercise, and other lifestyle factors.But with wider availability comes the need for a deeper understanding of how to interpret the data generated by these devices.
New Research Examines CGM Accuracy Across Different Groups
Researchers at Mass General Brigham in Boston undertook a study involving 972 participants aged 40 and older to evaluate the reliability of CGM readings. The study group encompassed individuals with type 2 diabetes (421 participants), prediabetes (319 participants), and normal blood sugar levels (232 participants). The findings, recently published, indicate that while CGMs perform accurately for those with diabetes, their readings are less consistent in individuals with prediabetes or normal glucose metabolism.
Key Findings Summarized
| Group | Diabetes | Prediabetes | Normal Glucose |
|---|---|---|---|
| Average Glucose Accuracy | High | Moderate | Low |
| Time in Range Accuracy | High | Moderate | Low |
| Predictive Value for Long-Term Health | Established | Unclear | Unclear |
According to Dr. Jorge Rodriguez, an internal medicine physician involved in the research, the value of CGMs for those without diabetes currently lies in tracking short-term effects. “CGMs can definately help individuals observe how specific foods, exercise routines, and sleep patterns influence their glucose levels in real-time,” he explained. he shared a personal anecdote about discovering the unexpected impact of rice noodles in a soup on his own glucose levels while using an over-the-counter CGM.
Did You No? According to the Centers for Disease Control and Prevention, over 37.3 million Americans have diabetes, and 96 million adults have prediabetes. CDC Diabetes Statistics.
The Need for Longitudinal Studies
The current study was cross-sectional, meaning data was collected at a single point in time. Dr. Rodriguez emphasized the need for long-term studies to determine whether CGM patterns in non-diabetic individuals can effectively predict the risk of developing conditions like diabetes, heart disease, or stroke. More thorough research is essential to fully understand the clinical implications of CGM data in a wider population.
Pro Tip: If your considering using a CGM without a diabetes diagnosis, consult with a healthcare professional to discuss potential benefits and limitations, and to ensure proper interpretation of the data.
Understanding Glucose Monitoring: A Deeper Dive
Glucose monitoring, whether through customary blood tests or newer continuous monitoring systems, plays a crucial role in managing overall health. By tracking glucose levels,individuals can gain insights into their metabolic function and make informed lifestyle choices. The accuracy of these measurements is paramount,which is why recent research focusing on the reliability of CGMs is so vital.
Beyond diabetes, understanding glucose fluctuations can be valuable for athletes, individuals focused on weight management, and anyone interested in optimizing their energy levels and overall well-being. However, it’s crucial to remember that glucose levels are influenced by a myriad of factors, including diet, exercise, stress, and sleep.
Frequently Asked Questions about Continuous Glucose monitors
- What is a continuous glucose monitor? A CGM is a small device worn on the body that continuously tracks glucose levels throughout the day, providing real-time data.
- Who can benefit from using a CGM? Traditionally used by people with diabetes,CGMs are now being explored for use by individuals without diabetes who are interested in tracking their metabolic health.
- Are over-the-counter CGMs accurate for everyone? Research suggests that CGMs are highly accurate for individuals with diabetes but less reliable for those with prediabetes or normal blood sugar levels.
- Can a CGM predict future health risks? More research is needed to determine if CGM patterns can predict the progress of chronic diseases like diabetes or heart disease in non-diabetic individuals.
- Should I consult a doctor before using a CGM? Yes, it is recommended to consult with a healthcare professional to discuss the potential benefits and limitations of using a CGM.
- What is the difference between average glucose and time in range? Average glucose provides an overall snapshot of blood sugar levels, while time in range indicates the percentage of time glucose levels fall within a target range.
- How do lifestyle factors affect glucose levels? Diet, exercise, sleep, and stress all have a significant impact on glucose levels and can be tracked using a CGM.

What are Over-the-counter Continuous Glucose Monitors (CGMs)?
Traditionally, continuous glucose monitoring (CGM) systems were exclusively available to individuals diagnosed with diabetes. These devices track glucose levels throughout the day and night, providing a dynamic picture of blood sugar fluctuations – far beyond what conventional finger-prick testing offers. Now, with the rise of wellness technology, several companies offer over-the-counter CGMs (OTC CGMs) marketed towards individuals without diabetes. These devices aim to provide insights into how diet, exercise, and lifestyle impact glucose levels, empowering users to optimize their health. The core technology,leveraging principles of machine learning (as explained here), allows for increasingly accurate and personalized data analysis.
understanding Glucose Variability in Non-Diabetic Individuals
Even without a diabetes diagnosis, maintaining stable blood sugar control is crucial for overall well-being. Significant glucose variability – large swings in blood sugar – can contribute to:
* Energy crashes and fatigue: Frequent spikes and dips can leave you feeling sluggish.
* Cognitive impairment: Brain function relies on a steady glucose supply.
* Mood swings and irritability: Blood sugar fluctuations can impact neurotransmitter balance.
* Increased risk of chronic diseases: While research is ongoing, emerging evidence suggests a link between glucose dysregulation and conditions like heart disease and neurodegenerative disorders.
* Inflammation: High glucose levels can promote systemic inflammation.
OTC CGMs offer a way to see these fluctuations, providing data that traditional blood tests might miss. This is particularly relevant for those interested in biohacking, personalized nutrition, and preventative healthcare.
How Do OTC CGMs Differ from Medical-Grade CGMs?
While both types of CGMs measure glucose levels in interstitial fluid (the fluid between cells), key differences exist:
| Feature | Medical-Grade CGM | Over-the-Counter CGM |
|---|---|---|
| Intended Use | Diabetes Management | Wellness & Optimization |
| Accuracy | Higher, FDA-approved | Generally less accurate |
| Alerts | Hypoglycemia/Hyperglycemia Alerts | Typically fewer alerts |
| Data Reporting | Detailed, shareable with healthcare providers | Often simplified, app-focused |
| Cost | Higher (often insurance covered) | Lower upfront cost, ongoing subscription |
It’s important to note that OTC CGMs are not intended to diagnose or treat any medical condition. they are designed for informational purposes only. Accuracy can vary between brands, and users should be aware of potential limitations. Look for devices with published accuracy studies and understand the sensor accuracy specifications.
