Exogenousness can be deciphered as an external influence. The concept of "exogenous factors" is used in economics, mathematics, and medicine. Its meaning consists in external predetermination, the assignment of any parameters, regardless of the functioning of the model against which they are considered. Endogeneity is the opposite term that carries information about internal processes.
Determination of exogenicity in medicine
When describing exogenous factors, for example, in medicine, it is always taken into account that this effect is external. Thus, not only infections, the danger of injury, but also social conditions affect human health. After all, proper nutrition, a healthy lifestyle directly depends on the individual's income. This means that this is also one of the factors of external influence on the body.
Variations of exogenous factors affecting the state of health can be as follows:
- living conditions of a person in society, at home;
- the presence or absence of preventive actions;
- infections, injuries, medications.
Exo in Greek means "external," and genes means "generated." And most often this term is used in scientific works in the study of diseases or other problems. So, in biology, the exogenous layer of tissue is understood as the outer, superficial.
Studying the conditions for the formation of health problems
The manifestation of exogenous factors is the action or influence of pathogenic microorganisms on the human body, causing various pathologies. The reasons for the development of diseases are carefully studied, and the results of studies develop mechanisms to protect the patient from the influence of external adverse conditions. Thanks to preventive measures, dangerous pathologies are prevented.
External factors are divided into two groups:
- Indirect factors - this includes infections, viruses, diseases that lead to the inflammatory process, as a result of which the pathology in question is formed. Such, for example, is the effect of contaminated water on the appearance of oncology.
- Direct action factors are circumstances directly causing the pathology in question. Such are, for example, parasitic infections (echinococcus, which causes proliferating cysts in the lungs).
It all depends on the point of view
Exogenous and endogenous factors are relative definitions, the semantic meaning of which varies depending on the point of view of the situation. So, the state of the environment becomes an invariable external condition for a person. If we consider the conditions for the occurrence of diseases in a separate organ, then the external negative causes of the formation of pathology in it can also be disorders of the digestive system.
And the disruption of the endocrine system can be both an internal factor and external to any area of the body under consideration.
The influence of exogenous factors on the occurrence of complications
When considering any pathology of the body, external and internal conditions that lead to complication are always taken into account. Excluding possible risks, oncology, the spread of epidemics can be avoided, and the formation of incurable inflammations can be prevented.
In this area of research, exogenous resistance factors occupy an important place - or otherwise, the body's ability to resist environmental adverse conditions.
External causes of complications are:
- mechanical;
- physical;
- biological;
- chemical.
Exogenous and endogenous factors affect the nervous, endocrine, circulatory, lymphatic systems of a person. Immunity is the first to suffer, and its weakening makes it possible to develop a huge number of pathogens. Therefore, when studying the sources of diseases, it is important to consider all the possible risks of complications.
External causes of disease
Exogenous etiological factors include the social conditions of a person: nutrition, lifestyle, the presence of stressful conditions. The physical causes of the development of the disease include: the influence of electromagnetic fields and radiation, burns from sunlight, deterioration in well-being at elevated ambient temperatures.
To mechanical exogenous factors include: various damage to tissues and bones from direct contact with solid objects. Chemicals include poisoning by poisons, fumes of harmful gases, and poor food. Biological causes are the negative effects of pathogens.
The most common lesions of the body are parasites, bacteria, viruses, fungi. Infections most often cause dangerous diseases. Modern medicine takes into account the risk of exogenous penetration of microorganisms into the body of a healthy person. Preventive measures are being taken to combat their spread: vaccines, isolation, timely treatment, and literacy.
Internal causes of disease
When analyzing the risks of developing the disease, heredity is also taken into account. These are also exogenous factors. Examples of hereditary pathology transmission are very common. Often, chronic ailments are "written down" genetically. And in adulthood, such people are at a high risk of developing the diseases that their parents suffered.
An exogenous factor is a predisposition to the disease with allergies, color blindness, malformations of the internal organs, and vascular thrombosis. Dangerous are hereditary syphilis, HIV infection, parasites. Such a sick person can be a threat to others.
An internal factor that can influence the formation of chronic diseases is age, gender of a person, physical structure and body functions. Scientists share the causes of certain diseases in women and men. So, complications after pregnancy or sexual diseases in the stronger sex are considered in a separate vein.
Resistance to external threats
Given the causes of disease, it is important to compare exogenous risk factors with body resistance. Each person in a particular area of residence has a unique resistance to parasites and other infections. Throughout life, such people form a stable immunity.
Exogenous factors become the most important for the analysis of pathological conditions. Unfortunately, external stimuli cannot always be fully taken into account, which causes oncology, disability, and even death. But endogenous factors often lead to early death.
