CGM Interpretation: Time in Range, Targets & What They Mean
CGM interpretation explained: target range is 70 to 180 mg/dL, aim for over 70% time in range, based on at least 14 days of sensor data.

CGM Medication-Driven Changes: How GLP-1s, Metformin, SGLT2s, and Other Drugs Shift Your Continuous Glucose Monitor Readings
A guide to how common medications change continuous glucose monitor (CGM) readings, what normal and optimal CGM ranges look like, and how to interpret medication-driven glycemic shifts in real time.
CGM Rate-of-Change Interpretation: What Your Arrows Actually Mean
A guide to reading CGM trend arrows, understanding rate-of-change data, and using real-time glucose velocity to make safer, smarter decisions about food, exercise, and medication.
CGM Sex- and Cycle-Related Differences: What Your Continuous Glucose Monitor Readings Really Mean
How sex hormones and the menstrual cycle affect continuous glucose monitor (CGM) readings, normal ranges by sex, optimal targets, and what clinicians recommend for women on HRT or hormonal contraceptives.
Continuous Glucose Monitor (CGM) Interpretation by Decade of Life
How to read CGM data at every age, what target ranges come from guidelines versus clinical practice patterns, and a decision framework for choosing the right target tier based on age-related hypoglycemia risk.
Continuous Glucose Monitor (CGM) Longevity-Medicine Target Ranges
What CGM numbers actually predict long-term health, and what is still unproven. Evidence-based context for time-in-range, mean glucose, glycemic variability, and fasting glucose in non-diabetic adults using CGM for longevity purposes.
Continuous Glucose Monitor (CGM): Normal vs. Functional Optimal Ranges
Standard CGM reference ranges miss early metabolic dysfunction. Learn the difference between 'normal' and functionally optimal glucose targets, what the data shows, and how to act on your CGM readings.
Continuous Glucose Monitor (CGM): Nutrition and Fasting Impact
How food choices, meal timing, and fasting protocols change your CGM readings. Learn what normal and optimal glucose ranges look like, which nutrients spike glucose most, and how to act on CGM data to improve metabolic health.
Continuous Glucose Monitor (CGM): Training and Exercise Impact
How exercise changes CGM readings, what glucose ranges to target during training, and how to use real-time data to improve performance and metabolic health. Evidence-based guide prepared by the HealthRX.com Editorial Team.
Continuous Glucose Monitor (CGM): What This Test Actually Measures
A CGM tracks interstitial glucose every 1 to 5 minutes, generating up to 288 readings per day. Learn what it measures, normal ranges, key metrics like Time in Range, and how clinicians use CGM data to guide treatment.
Drugs That Distort CGM Readings: Medications That Cause False Highs and Lows
Acetaminophen, vitamin C, hydroxyurea, and other medications can produce inaccurate continuous glucose monitor readings. Learn which drugs interfere with CGM sensors and how to protect your data.
Evidence-Based Ways to Improve Your Continuous Glucose Monitor (CGM) Numbers
Clinically supported strategies to optimize CGM readings, reduce glycemic variability, and maintain time-in-range targets backed by ADA, AACE, and Endocrine Society guidelines.
