Viscoelastic and Viscoplastic Glucose Theory (VGT #19): Applying Theories of Viscoelasticity and Viscoplasticity from Engineering and Energy Theory from Physics for Three PPG Cases to Compare the Energy Loss in Loading-Unloading Process via Three Hysteresis Loop Areas Along with Comparing Three PPG Associated Energies via Time-Domain and Frequency-Domain Based on the GH-Method: Math-Physical Medicine (No. 598)

Abstract

Recently, the author applied theories of elasticity, plasticity, viscoelasticity, and viscoplasticity from engineering along with the theories of wave and energy from physics to conduct his research on output biomarkers (symptoms or behaviors) resulting from a suspected or identified input biomarkers (causes or stressors). As a result, he has written a series of 18 different articles. In this research, he studies two related topics of glucose energy utilizing a continuous glucose monitoring (CGM) sensor device that collected postprandial plasma glucose (PPG) from 4,168 meals during the period from 5/5/2018 to 2/6/2022. The first one is the energy loss of hysteresis loops via VGT analysis. The second one is the PPG associated relative energy level in time-domain (TD) and frequency-domain(FD) through wave theory and energy theory of physics. He then compares his 3 respective energy results corresponding to 3 PPG cases: PPG between 0 mg/dL to 400 mg/dL, PPG < 120 mg/dL, and PPG >160 mg/dL.
