[edit] Environmental factors inducing diseases
Apart from the true monogenic genetic disorders, environmental factors 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[quantify] personal-care products and household cleaners are common environmental factors that determine 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.
As an example of an environmental trigger, a component of a human's drinking water may activate (trigger) a change in a person's body. Such changes are mainly negative ones.[citation needed] Using this example, what is in the drinking water may affect one person entirely differently than another – someone may be affected greatly, whereas someone may not be at all.
Many cancers (osteosarcoma, etc.), along with a plethora of other diseases, are thought[by whom?] to be a result of environmental triggers.[citation needed]
Nitrates may be an environmental trigger for Alzheimer's, diabetes, and Parkinson's disease.[2]
Environmental triggers for asthma[3] and autism[4] have been studied too.
[edit] Other
Environmental factors such as the weather affect business interests.[citation needed]
