By constant use the malevolent nature and the discomfort of sickness have commingled in the two words illness and disease. In many cases, terms such as disease , disorder, morbidity and illness are used interchangeably. The term disease broadly refers to any condition that impairs the normal functioning of the body. For this reason, diseases are associated with dysfunctioning of the body's normal homeostatic process. An infection that does not and will not produce clinically evident impairment of normal functioning, such as the presence of the normal bacteria and yeasts in the gut, or of a passenger virus, is not considered a disease.

By contrast, an infection that is asymptomatic during its incubation period, but expected to produce symptoms later, is usually considered a disease. Non-infectious diseases are all other diseases, including most forms of cancer, heart disease, and genetic disease. Illness and sickness are generally used as synonyms for disease. Illness is often not due to infection, but a collection of evolved responses—sickness behavior by the body—that helps clear infection. Such aspects of illness can include lethargy, depression, anorexia, sleepiness, hyperalgesia, and inability to concentrate.
Interestingly, the current use of the words, reverses the etymological implications with disease representing the objective nature, and illness representing the subjective experience of a malady. The difference is less in their actual meaning and more in their purported usage. In olden days, any ailment was a disease, but now 'known' or 'easily recoverable' ailment is considered illness and those that required severe, life-death type treatment are considered diseases.

So 'fever' is considered illness, while 'malaria' or 'jaundice' is disease. We see that Oald says the words illness and disease are synonyms, the University of Ottowa wants to see semantic differences, but I am sure that such distinctions are unknown to almost any speaker. My experience is that illness is preferred in spoken language and disease is often used in texts that have medical topics such as Alzheimer's disease. But you find illness in such texts as well.

The main effect of a disease is felt when a particular organ of the body or the body as a whole fails to maintain its condition of balance and stability. This condition is referred to in medical terms as homeostasis. It is important to note that both illness and disease result in more or less the same symptoms. However, an illness can be cured in most cases. For instance, cold , flu or gastrointestinal diseases can be cured by treatment. However, there are a number of diseases that cannot be cured.

I like this article because in this article the writer work so beautifuuly and teach the persons so nicely and huredly. Thank You so much for the information! Successful work You have done! Interesting article, but a bit simplistic. The presence of pathogens is not necessary for disease to occur, and knowing the cause of disease is not necessary to identify it as a disease.

In the case of disease, dysfunction is observed phenomenology , then one looks for the underlying mechanism for that dysfunction pathophysiology , and from there one attempts to identify the cause etiology. But, many diseases have unknown causes, and many have only partly understood mechanisms. Be mindful of this, because not all biomedical researchers carry the same assumption as the author of this article.
I wish people would stop making a simple explanation difficult. All a person has to do in this instance is call it a disease when there is an outside pathogen entering the body and an illness when there is NO outside pathogen. Why do they feel it demeaning to call alcoholism an illness and not a disease? What possible difference would it make if we used concrete pathogens for disease and everything else such as mental problems illnesses?
If mental illnesses were brain diseases — of known, or unknown, aetiology- they would be pathologies of the central nervous system, and not illnesses of the mind.

As such, they should be treated by neurologists, not psychiatrists, and all of psychiatry should be absorbed or absorbable by neurology. Not only does this show no indication of occurring, but it cannot occur. Psychiatrists do things that no neurologist does or can legally do -namely, to take and treat as a patient someone who wants nothing to do with him.
