Abstract

Gerald C. Hsu

This article is an extension work of his previous research result of a “simple linear equation of predicted postprandial plasma glucose (PPG)” as shown below: Predicted PPG= (FPG * 0.97) + (carbs/sugar grams * M2) - (post-meal waking K-steps * 5) This article contains special research on the linear elasticity of glucose behaviors with his newly defined GH-modulus (M2) cited in References 7, 8, and 9. The author makes an analogy of stress, strain, and Young’s models from engineering strength of materials and theory of elasticity with carbs/sugar (carbs) intake amounts, incremental PPG (PPG delta) and GH-modulus of endocrinology and biomedical science. There are three parts to the study. In the first part, by using the 6 years of collected data, he attempts to prove a “linear elastic relationship” existing between carbs and PPG delta via the existence of GH-modulus as the “slope” of their straight-line linear relationship. For the second part, through 9-months data of two diabetes clinical cases, he discovered that the magnitude for the GH-modulus is proportional to the diabetes severity of the patients. This means that the GH-modulus is clearly “material” dependent on the patient’s conditions. In the third part, by examining 7- months data of three diabetes clinical cases, he uncovered the magnitude of GH-modulus varying month to month for all of these three patients. As a result, the GH-modulus is evidently “time” dependent as well.
