Continuous Glucose Monitoring: What You Should Know & Why Sensor Patches Matter

Continuous glucose monitoring (CGM) is transforming diabetes care by offering ongoing insights into how glucose levels fluctuate throughout the day and night. But for CGM to work well, the sensor needs reliable adhesion and skin protection. That’s where a high-quality medical adhesive patch comes in — like the one we develop at Ceeport.

In this post, we’ll cover:

1. Can you get a CGM without a doctor?
2. How Can I Get a CGM?
3. What Issues Could You Encounter While Using a CGM?

Let’s dive in.

Can I Get a CGM Without a Doctor?

Yes, you can get a continuous glucose monitor (CGM) without a doctor for certain models, such as the Dexcom Stelo and Abbott's Lingo system, which are approved for over-the-counter (OTC) use.

The Rise of OTC CGM

Historically, CGM devices have been prescription-only. In 2024, the FDA cleared the Dexcom Stelo as the first over-the-counter (OTC) integrated CGM system for people aged 18+ who do not use insulin.
This change opens access for individuals who want to track glucose trends without direct medical oversight. However, experts caution that interpreting CGM data without clinical context can be risky.

Important Considerations & Limitations

OTC CGMs may not include hypoglycemia or hyperglycemia alarms, making them unsuitable for high-risk users. U.S. Food and Drug Administration

For people without diabetes, CGM readings may not reliably correlate with HbA1c or long-term glucose control. A 2025 study found that CGM metrics aligned weakly with HbA1c in non-diabetic individuals. 

Using CGM without a doctor’s guidance may lead to misinterpretation, unnecessary anxiety, or incorrect decisions. Harvard Health+1

So yes, you can get a CGM without a doctor in some markets now — but you should do so cautiously and ideally with medical support.

How Can I Get a CGM?

Prescription Route

For many users, CGM is still obtained via prescription from a physician or endocrinologist, often bundled via diabetes care programs or insurance coverage.

OTC / Consumer Purchase

With devices like Dexcom Stelo, CGMs are becoming available over the counter for suitable populations. U.S. Food and Drug Administration+1
Still, OTC availability depends on local regulatory clearance, market availability, and whether the user meets eligibility criteria (e.g. non-insulin users).

What Issues Could You Encounter While Using a CGM?

• Skin Irritation & Adhesive Sensitivity
• Long-term contact with adhesives can cause irritation, rashes, or allergic reactions in some users. Choosing hypoallergenic, breathable adhesives is key.
• Sensor Detachment
• Sweat, movement, water exposure, or friction may cause adhesive failure, leading to sensor lift or detachment. A good protective patch layer can reduce this risk.
• Signal Loss or Data Gaps
• If the sensor loses contact or becomes dislodged, data may drop out or become less reliable.
• Interpretation & Calibration Challenges
• Some CGM systems still require occasional fingerstick calibration. Misplacement or poor adhesion can lead to sensor drift or errors. PMC

How Ceeport’s CGM Patch Helps (Integrating Medical Dressing Expertise)

Because CGM sensors must remain adhered for 10–14 days (sometimes up to 15 days depending on the system) and typically endure movement, sweat, water exposure, and skin stress, the overlaying patch must meet high standards.

Here’s how Ceeport’s medical adhesive CGM patch is designed to address these challenges:

By applying a robust, skin-friendly patch, the CGM sensor is more likely to remain stable and accurate throughout its wear period — even during exercise, showers, or daily life.

Final Thoughts & Call to Action

CGM is a powerful tool that gives continuous insights into glucose dynamics — and with the recent rise of OTC options, access is expanding. But even the best sensor is only as good as its adhesion and skin interface.

By marrying medical dressing technology with diabetes device needs, Ceeport’s CGM patch plays a crucial role in protecting the sensor, preserving data integrity, and minimizing skin issues.

If you or your users are considering CGM, make sure you pair it with a reliable, skin-compatible patch — and feel free to explore what we offer:
