Using GH-Method: Math-Physical Medicine, Fourier Transform, and Frequency Segmentation Pattern Analysis to Investigate Relative Energy Associated with Glucose

Corresponding Author: Gerald C. Hsu, eclaireMD Foundation, USA.

This paper provides research findings on glucose created relative energy by using sensor collected glucose data from a period of 376 days from 5/5/2018 to 5/15/20.  The dataset is provided by the author, who uses his own type 2 diabetes metabolic conditions control, as a case study via the “math-physical medicine” approach of a non-traditional methodology in medical research.

Math-physical medicine (MPM) starts with the observation of the human body’s physical phenomena (not biological or chemical characteristics), collecting elements of the disease related data (preferring big data), utilizing applicable engineering modeling techniques, developing appropriate mathematical equations (not just statistical analysis), and finally predicting the direction of the development and control mechanism of the disease.

The author was diagnosed with type 2 diabetes (T2D) in 1995.  He has measured his Finger glucoses four times a day since 2012.  He has uploaded his 10,760 Finger glucose big data of 7.5 years or 2,690 days on a cloud server.  On 5/5/2018, he applied a Sensor on his upper arm to collect 27,448 glucose data: 376 days from 5/5/2017 to 5/15/2019 with 73 data per day.

Based on this big dataset, various glucose patterns and their moving trends can be observed and analyzed through further mathematical and statistical operations, including time/series, spatial, artificial intelligence, and frequency domain analyses.  Finally, he utilized his acquired medical domain knowledge to link his mathematical results with biomedical interpretations in order to discover some hidden facts and their potential dangers to his health.

He applied the wave theory and Fourier Transform to transfer glucose waveforms from time domain (Time) to frequency domain (Frequency).

Here are three variable sets:

  • GT – glucose in Time
  • G2 – glucose square
  • AF – Amplitude in Frequency

Here are some of his research findings:

  1. The highest glucoses in Time are corresponding to the lowest amplitudes in Frequency. The same observation holds true for both FPG and PPG data diagrams.
  2. According to physics, energy associated with a wave is proportional to the square of the wave’s amplitude.  Through three pairs of high existing triangular correlation coefficients, it indeed proves that the amplitude in Frequency is the “relative” energy level of glucose in Time (Figure 1): 99.5% between GT and G2; 72.3% between GT and AF; and 70.8% between G2 and AF.
  3. The author further segmented the glucose/frequency data into four groups with different frequency ranges, 0-1, 0-5, 0-10, 0-15.  Through this frequency segmentation pattern analysis (Figure 2) of GT, G2, and AF, the more inclusion of lower glucose values in a particular segmented group.  Their corresponding averaged frequency number would increase, but their associate averaged energy level would decrease.

The author’s research work proves the amplitude of Frequency domain is associated with relative energy level carried by glucose of Time domain.   This energy is circulating inside the human body to provide the needed energy.  However, when “excessive” energy associates with “high” glucose in circulation, their impact will damage the internal organs, i.e.  diabetes induced complications such as CVD, stroke, foot ulcer, renal and eye problems.  This quantitative analysis not only provides mathematical proof of biomedical phenomena but also offers extra tools for estimating the risk probabilities of various diabetes complications.
