What is 14-Day Glucose Monitoring?

14-day glucose monitoring uses a small, discreet sensor (such as the FreeStyle Libre 14 Day system) worn on the back of your upper arm.

• The sensor continuously measures glucose levels in the interstitial fluid every minute and records readings every 15 minutes.

• After a 1-hour warm-up period, you can scan the sensor with a reader or smartphone app to view current glucose levels, trends, and an 8-hour history.

• No fingerstick calibrations are required.

• The sensor is waterproof and can be worn for up to 14 days.

This technology gives you and your doctor a complete picture of your glucose patterns throughout the day and night — including highs, lows, and how your levels change over time.

Why 14-Day Glucose Monitoring is Important

Traditional fingerstick testing only provides single-point snapshots. In contrast, 14-day CGM reveals trends and patterns that help identify:

• How specific foods affect your blood sugar

• The impact of exercise and stress

• Nighttime glucose fluctuations

• Effectiveness of your current diabetes medications

This data allows for more precise, personalized treatment adjustments and better long-term blood sugar control.

Importance of Follow-Up with Your Physician

The real value of 14-day glucose monitoring comes from reviewing the data with your doctor. At Suntree Internal Medicine, we strongly recommend scheduling a follow-up appointment after your monitoring period.

During this visit, your physician will analyze the glucose reports with you and make targeted recommendations to improve your diabetes management, reduce risks, and enhance your overall health. 

Consistent follow-up helps ensure the insights gained from CGM lead to meaningful improvements in your care.
