CGM vs Inflammation Monitoring: Two Different Signals
Continuous glucose monitors like Levels, Lingo, and Stelo show how your body handles food, hour by hour. Sensa shows how much inflammation your body is carrying, week by week. Here is what each signal actually tells you.
A continuous glucose monitor (CGM) and an inflammation monitor measure different things, so one cannot replace the other. A CGM tracks blood glucose minute by minute, showing your metabolic response to meals, exercise, sleep, and stress. Sensa measures C-reactive protein (CRP), the standard marker of systemic inflammation, which no CGM measures. Glucose tells you how you responded to lunch; CRP tells you the inflammatory load your body has been carrying over recent days and weeks. Many people track both for a fuller picture of their health.
The CGM Boom, and the Signal It Misses
Continuous glucose monitoring has moved from diabetes care into mainstream wellness. Over-the-counter sensors like Abbott's Lingo and Dexcom's Stelo, and programs like Levels built on top of them, let anyone watch their glucose respond to a bowl of pasta or a bad night of sleep in near real time. It is genuinely useful feedback, and it made continuous biomarker tracking a normal consumer habit.
But glucose is one axis of health: the metabolic one. Inflammation is a different axis. It is the immune system's background activity level, and chronically elevated inflammation is linked to cardiovascular risk, mood, recovery, and aging. You can have flat, healthy glucose curves and still carry elevated inflammation from poor sleep, chronic stress, or a smoldering issue you cannot feel.
No CGM measures inflammation. CRP is the marker clinicians actually use for that, and until recently the only way to check it was a blood draw. Sensa makes CRP trackable at home the way a CGM made glucose trackable, just on the cadence that fits inflammation: repeat spot checks over days and weeks rather than a continuous stream.
Different Timescales, Different Questions
Glucose swings in minutes, so it needs continuous measurement. A CGM answers: "How did my body handle that meal, that workout, that night of sleep?"
CRP moves over hours to days and settles into a baseline over weeks. Regular spot checks answer: "Is the way I am living pushing my inflammation up or down?"

Not competitors so much as two different instruments. Here is how they differ.
| Continuous Glucose Monitor (Levels, Lingo, Stelo) | Sensa At-Home CRP Device | |
|---|---|---|
| What It Measures | Blood glucose (metabolic response) | C-reactive protein (systemic inflammation) |
| What It Tells You | How your body responds to meals, exercise, sleep, and stress in real time | The inflammatory load your body has been carrying over recent days and weeks |
| How You Use It | A sensor worn on the arm, applied with a spring-loaded needle, replaced every 1 to 2 weeks | An on-demand saliva test, no wearable and nothing under the skin |
| Measurement Cadence | Continuous readings around the clock while the sensor is worn | Spot checks whenever you choose, matched to how CRP actually changes |
| Ongoing Cost | New sensors every 2 weeks, often plus an app subscription, commonly $50 to $100+ per month | One device plus affordable strips, no sensor replacement cycle |
| Detects Inflammation | No. Glucose is not an inflammation marker | Yes. CRP is the standard systemic inflammation marker |
| Best For | Metabolic awareness: meal responses, glucose stability, energy management | Inflammation awareness: recovery, lifestyle impact, long-term inflammatory baseline |
Which Signal Do You Need?
If you are choosing where to start, match the tool to the question you are asking about your body.
A CGM answers questions like...
- Which foods spike my glucose, and which keep it stable?
- Why do I crash mid-afternoon, and how do I fix it?
- How do exercise timing and sleep affect my metabolic response?
- Am I trending toward better or worse glucose control over months?
- How does alcohol or a late meal change my overnight readings?
Sensa answers questions like...
- Is my baseline inflammation in a healthy range?
- Is my new diet, exercise routine, or stress practice actually lowering my inflammation?
- Am I recovering from hard training, or quietly accumulating inflammatory stress?
- Did that period of poor sleep or high stress show up in my body?
- Is my inflammation trending down over the months I have been making changes?
What Your CRP Number Means
High-sensitivity CRP (hsCRP) is measured in milligrams per liter (mg/L). These widely referenced cardiovascular risk ranges are educational and not a substitute for a healthcare provider's interpretation.
| hsCRP level (mg/L) | Category | What it typically reflects |
|---|---|---|
| Below 1.0 | Low risk (optimal) | Low inflammatory activity |
| 1.0 to 3.0 | Average risk | Common range; may reflect diet, stress, or sleep |
| Above 3.0 | High risk | Meaningful inflammatory activity |
| Above 10.0 | Acute | Often an active infection or injury; consult a provider |
Ranges based on high-sensitivity CRP standards from the American Heart Association. Sensa is a general wellness product; these values are educational and not medical advice.
How Sensa Measures CRP at Home
Sensa uses a saliva-based lateral flow assay to detect CRP concentration. No wearable sensor, no needles, no subscription treadmill.
Collect a Saliva Sample
Use the collection tool included with your Sensa kit. No preparation needed. The whole process takes about 30 seconds.
Insert the Test Strip
Apply your sample to the Sensa test strip. The strip uses a lateral flow assay to detect CRP concentration in your saliva.
Read Your Result in the App
Scan the strip with the Sensa app to get your CRP reading in minutes. Your results are logged automatically so you can track trends over time.
Frequently Asked Questions
Does a CGM measure inflammation?
No. A continuous glucose monitor measures glucose in the interstitial fluid under your skin, which reflects your metabolic response to food, activity, and sleep. Inflammation is measured with markers like C-reactive protein, which requires a different kind of test. Sensa measures CRP from saliva at home.
Are glucose and inflammation related?
They influence each other. Chronically elevated glucose and frequent large spikes are associated with higher inflammatory activity, and chronic inflammation can in turn worsen insulin resistance. But the relationship is loose enough that one cannot stand in for the other. Stable glucose does not guarantee low inflammation, which is why they are worth tracking separately.
Why is Sensa not continuous like a CGM?
Because CRP does not need continuous measurement. Glucose swings meaningfully within minutes, so a CGM samples constantly. CRP changes over hours to days and forms a baseline over weeks, so regular spot checks capture the trend that matters without wearing a sensor. The cadence of the tool matches the biology of the marker.
Should I use a CGM and Sensa together?
If you want a fuller picture, they pair well. A CGM shows the short-term metabolic effects of your choices, and Sensa shows the longer-term inflammatory effects. The same lifestyle levers, diet quality, sleep, exercise, and stress management, tend to improve both signals, so seeing them move together is powerful feedback.
You Track Your Glucose. Now Track Your Inflammation.
Sensa adds the signal your CGM cannot see: a simple, painless CRP reading at home, logged automatically so you can watch your inflammatory baseline respond to how you live.
