Key Metrics to Monitor

Essential data points for optimal glucose control

1

Time in Range (TIR)

Track the percentage of time your glucose stays within your target range (70-180 mg/dL). This metric provides the clearest picture of your overall glucose control.

Excellent: 70%+ time in range
Good: 60-70% time in range
Needs improvement: <60% time in range
2

Glucose Variability

Analyze patterns in your daily glucose fluctuations. Consistent, moderate variations are normal, while extreme spikes indicate areas for lifestyle improvement.

Low variability: Smooth, gentle curves
High variability: Sharp spikes and drops
Focus: Reduce extremes
3

Post-Meal Response

Use your CGM to see how specific foods impact your glucose levels, helping you make better dietary choices and avoid problematic foods.

Normal peak: 1-2 hours after eating
Return to baseline: 3-4 hours
Target peak: <180 mg/dL
4

Exercise Impact

Monitor how physical activity affects your glucose levels in real-time, essential for planning workouts and understanding metabolic responses.

During exercise: May rise or fall
After exercise: Better sensitivity
Long-term: Improved control

Dietary Optimization

  • Identify foods causing glucose spikes
  • Test portion sizes and meal timing
  • Experiment with food combinations
  • Track macronutrient ratio effects

Exercise Planning

  • Understand exercise glucose effects
  • Optimize workout timing
  • Monitor recovery periods
  • Plan workout nutrition

Sleep & Stress Impact

  • Monitor sleep quality effects
  • Track stress-related changes
  • Identify routine patterns
  • Correlate lifestyle factors

Read Your CGM Data Like a Pro

Master the art of glucose pattern recognition

Daily Pattern Recognition

Morning (Fasting)

Look for consistent baseline readings between 70-99 mg/dL upon waking

Post-Meal Peaks

Normal peaks occur 1-2 hours after eating, ideally staying under 140 mg/dL

Overnight Stability

Glucose should remain relatively stable during sleep with minimal fluctuations

Warning Signs to Watch

Frequent Spikes Over 180 mg/dL

May indicate need for dietary adjustments or medical consultation

High Variability

Extreme ups and downs suggest need for lifestyle modifications

Prolonged Elevations

Glucose staying high for hours after meals needs attention

Insurance and HSA/FSA Eligibility

Current Coverage Status

Limited Insurance Coverage

Since these are over-the-counter devices, traditional insurance coverage is limited, creating potential access barriers based on economic status.

HSA/FSA Eligible

Dexcom Stelo, Lingo, and related adhesive patches are HSA/FSA eligible, providing some financial relief for users with health savings accounts.

Prescription vs. OTC Comparison

Prescription CGMs

Typically covered by insurance with copays ranging from $10-$60/month

OTC CGMs

No insurance coverage but no prescription barriers

Access Trade-off

Immediate access without healthcare provider involvement vs. potential high out-of-pocket costs

Value Proposition Analysis

For Type 2 Diabetes Management

The monthly cost of OTC CGMs represents a significant investment, but clinical data shows CGM use helps people:

  • Improve glucose control and lower HbA1c
  • Decrease diabetes-related hospital admissions
  • Improve quality of life and reduce diabetes burden
  • Enable proactive diabetes management

For Wellness and Prevention

For pre-diabetic individuals or those focused on metabolic health, the cost may be justified by:

  • Early intervention potential and prevention benefits
  • Lifestyle optimization and behavioral insights
  • Preventing progression to type 2 diabetes
  • Personalized nutrition and exercise guidance

ROI Calculation for Diabetes Management

Annual CGM cost: $1,200
Potential medical cost savings: $2,000-5,000
Quality of life improvement: Priceless

Net annual benefit: $800-3,800

Market Impact

The potential market includes approximately 96 million people with prediabetes in the U.S. and roughly 25 million people with type 2 diabetes who don't use insulin.

Troubleshooting Common Issues

Sensor Adhesion Problems

Issue: Sensor falling off before wear period ends

Solutions:

  • • Use additional adhesive patches (many third-party options available)
  • • Ensure skin is completely clean and dry before application
  • • Avoid lotions or oils in the application area for 24 hours before insertion
  • • Consider specialized CGM adhesive patches like Skin Grip products

Connectivity Issues

Issue: Bluetooth connection dropping or sensor not pairing

Solutions:

  • • Ensure phone stays within 20 feet of the sensor
  • • Restart the app and re-establish Bluetooth connection
  • • If pairing takes longer than 5 minutes, follow manufacturer troubleshooting guidelines
  • • Keep the app open and active for optimal data transmission

Data Accuracy Concerns

Issue: Glucose readings seem inconsistent or inaccurate

Solutions:

  • • Remember that CGMs measure glucose in interstitial fluid, not blood, creating a few minutes of lag time
  • • Avoid compression on the sensor site
  • • Note that factory calibration eliminates the need for fingerstick calibrations
  • • Contact manufacturer support if readings consistently seem off

Skin Reactions

Issue: Irritation or allergic reactions at sensor site

Solutions:

  • • Use hypoallergenic adhesive barriers
  • • Rotate sensor placement sites
  • • Clean area gently with mild soap after sensor removal
  • • Consult healthcare provider for persistent skin reactions

App and Software Issues

Issue: App crashes or data not displaying correctly

Solutions:

  • • Update to the latest app version
  • • Restart your phone
  • • Check device compatibility requirements
  • • Clear app cache and reinstall if necessary

Sensor Performance Issues

Issue: Approximately 20% of sensors may not last the full wear period

Solutions:

  • • Contact manufacturer for sensor replacement if failure occurs early
  • • Keep extra sensors on hand for continuity
  • • Document any premature failures for warranty claims
  • • Follow proper application procedures to maximize sensor life

Future of OTC CGM Technology

Revolutionary Developments on the Horizon

The introduction of over-the-counter CGMs represents just the beginning of a healthcare revolution. Abbott plans to build on their platform with additional biomarkers, including sensors that can measure glucose and ketones simultaneously.

Multi-Biomarker Monitoring

Future sensors will track multiple metabolic markers simultaneously, providing comprehensive health insights beyond glucose alone.

AI-Powered Insights

Machine learning algorithms will provide personalized recommendations based on individual glucose patterns and lifestyle factors.

Prevention Focus

Enhanced early intervention capabilities for pre-diabetic individuals, potentially preventing millions of type 2 diabetes cases.

Market Impact Projections

96 Million
People with prediabetes in the U.S.
25 Million
Type 2 diabetes patients who don't use insulin
121 Million
Total potential OTC CGM market

Industry experts predict that OTC CGM adoption will accelerate diabetes prevention efforts and enable earlier intervention for pre-diabetic individuals.

Making Your Decision: Key Takeaways

Choose an OTC CGM if you:

  • Have type 2 diabetes and don't use insulin
  • Want to understand your metabolic health without prescription barriers
  • Are committed to the monthly cost investment
