Environmental Disorders

In epidemiology, environmental disease is disease caused by environmental factors that are not transmitted genetically or by infection. Apart from the true monogenic genetic disorders, environmental diseases may determine the development of disease in those genetically predisposed to a particular condition. Stress, physical and mental abuse, diet, exposure to toxins, pathogens, radiation, and chemicals found in almost all personal care products and household cleaners are possible causes of a large segment of non-hereditary disease. If a disease process is concluded to be the result of a combination of genetic and environmental factor influences, its etiological origin can be referred to as having a multifactorial pattern.


There are many different types of environmental disease including:

Lifestyle disease

Such as cardiovascular disease, diseases caused by substance abuse such as alcoholism, and smoking-related disease

Disease caused by physical factors in the environment

Such as skin cancer caused by excessive exposure to ultraviolet radiation in sunlight

Disease caused by exposure to chemicals in the environment

Such as toxic metals
