We use Physics ideas and equations to explain and to provide quantitative results of a possible measurement of the charges of albumin in the human kidney. Basically we use the diffusion equation and it is interpreted as a charge density fluxing through out the last layers of the kidney in the urine formation space. This study is a combination of Physics ideas to solve and face concrete problems of global diseases by which the presence of novel and alternatives ideas would serve to tackle the possible complications of type-2 diabetes progress. Therefore the comprehension of the why of the progress of certain diseases might be seen from the Physics angle and thus to provide new alternatives to improve the quality of life of people.
