Abstract:
Introduction: This paper discusses glucose measurement results from two
different methods, finger piercing and testing strip (Finger) and Libre’s continuous
glucose monitoring system (Sensor).
Method: The author has been collecting a total of 9,490 glucose data by finger
measurement, including both fasting plasma glucose (FPG) once a day
since 1/1/2014 (1,825 days) and postprandial plasma glucose (PPG) three
times a day since 1/1/2012 (2,555 days). Recently, he has further collected
17,046 glucose data by applying a sensor on his upper arm to collect his
glucose values continuously. This sensor measurement is conducted in parallel
with his routine finger measurements. During the period of 5/5/2018
to 12/31/2018 (241 days), he has recorded his sensor glucose values about
71 times per day. The measurement rate is approximately every 15 minutes
during the day and every hour during the night. In summary, he has collected
a total of 964 waveforms- 241 FPG and 723 PPG. Other waveforms
generated between meals or from eating snack/fruit are not included in this
analysis.
Results: Sensor’s time of peak glucose: 60 minutes after first-bite; PPG rising
speed: 33 mg/dL per hour; PPG decaying speed: 20 mg/dL per hour (~60%
of rising); Finger’s average FPG/PPG: 110/116 mg/dL (as 100% baseline); Sensor’s
peak PPG & % over finger: 159 mg/dL & 138% (+43 mg/dL); Sensor’s
average PPG & % over Finger: 135 mg/dL & 117% (+19 mg/dL); FPG (periodfrom
00:00 to 07:00): Average FPG: 112 mg/dL; Peak (crest): 122 mg/dL; Valley
(trough): 106 mg/dL; Period of trough (from 3am to 5am).
Conclusion: In average, PPG peak occurs one hour after first-bite of meal, not
two hours after; PPG decaying speed is almost twice as slow than its rising
speed; Averaged sensor’s PPG is 16% higher (+19 mg/dL) than the Averaged
finger’s PPG; Peak sensor’s PPG is 36% higher (+42 mg/dL) than the Averaged
finger’s PPG; FPG wave is much calmer than PPG wave and FPG’s lowest
trough range occurs during the deep sleep stage (from 3am to 5am).
Biography:
Gerald C Hsu has completed his PhD in Mathematics and has been majored in Engineering at MIT. He has attended different universities over 17 years and studied seven academic disciplines. He has spent 20,000 hours in T2D research. First, he studied six metabolic diseases and food nutrition during 2010-2013, then conducted research during 2014-2018. His approach is math-physics and quantitative medicine based on mathematics, physics, engineering modeling, signal processing, computer science, big data analytics, statistics, machine learning and AI. His main focus is on preventive medicine using prediction tools. He believes that the better the prediction, the more control you have.
