One cannot complete the theme of medicine by generalizing and interpreting the achievements of science and practice, as they are continuous like life itself. One could only assess its specific period, which, in turn, should be continued. Therefore, the conclusion here is a preface at the same time: both a conclusion and an introduction to the future.
It should be noted that it is especially difficult to formulate a general theory on human processes in normal and pathological conditions, which must meet many common criteria and, accordingly, do the following:
► formulate an answer to the question of the essence of two categories, i.e. human health and disease, based on natural and scientific knowledge as well as philosophical and sociological concepts;
► proceed from dialectical and materialistic understanding of the social essence of man, to consider health and illness as manifestation of the person's life occurring in optimum conditions of his activity and functions performed by him in the state of health and in the conditions of constrained, violated, and limited freedom of such an activity in case of illness;
► claim that health is determined the effect of environmental factors (natural and social) and internal biological factors (hereditary and genetic, which are, however, environmental factors recorded in the chain of generations);
► prove the direct impact of lifestyle on health; emphasize the importance of adverse lifestyle factors, i.e. risk factors for emergence and development of diseases;
► in case of diseases, which are the most characteristic forms of pathology in modern conditions in economically developed countries, i.e. for mainly chronic diseases, to recognize multiplicity of causes, i.e. risk factors related to the features of environment and lifestyle of the population;
