What is Disease?
A disease is anything away from healthy state of mind and body.
it is an abnormal condition of an organism that impairs bodily functions, associated with specific symptoms and signs. It may be caused by external factors, such as invading organisms, or it may be caused by internal dysfunctions.
In many cases, the terms disease, disorder, morbidity and illness are used interchangeably...
Disease, Illness, and Disorder
Disease
This term broadly refers to any abnormal condition that impairs normal function.
Commonly, this term is used to refer specifically to infectious diseases, which are clinically evident diseases that result from the presence of pathogenic microbial agents, including viruses, bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions. An infection that does not produce clinically evident impairment of normal functioning is not considered a disease. Non-infectious diseases are all other diseases, including most forms of cancer, heart disease, and genetic disease..
Illness
Illness and sickness are generally used as synonyms for disease.
However, this term is occasionally used to refer specifically to the patient's personal experience of his or her disease.it is possible for a person to be diseased without being ill, (to have an objectively definable, but asymptomatic, medical condition), and to be ill without being diseased.
Illness is often not due to infection but a collection of evolved responses, sickness behavior, by the body aids the clearing of infection. Such aspects of illness can include lethargy, depression, anorexia, sleepiness, hyperalgesia, and inability to concentrate.
Disorder
In medicine, a disorder is a functional abnormality or disturbance.Medical disorders can be categorized into mental disorders, physical disorders, genetic disorders, behavioral disorders and functional disorders.
The term disorder is often considered more value-neutral and less stigmatizing than the terms disease or illness, and therefore is preferred terminology in some circumstances. However, the term disorder is also used in many other areas of medicine, primarily to identify physical disorders that are not caused by infectious organisms.
Medical condition & Morbidity
Medical condition
A medical condition is a broad term that includes all diseases and disorders, but also includes normal situations, such as pregnancy, that might benefit from medical assistance or have implications for medical treatments.
Additionally, the term medical condition is used as a synonym for medical state, where it describes a patient's current state, as seen from a medical standpoint.
Morbidity
Morbidity (from Latin morbidus: sick, unhealthy) refers to a diseased state, disability, or poor health due to any cause.The term may be used to refer to the existence of any form of disease, or to the degree that the health condition affects the patient. Among severely ill patients, the level of morbidity is often measured by ICU scoring systems.
Co-morbidity is the simultaneous presence of two medical conditions, such as a person with schizophrenia and substance abuse.
In epidemiology and actuarial science, the term morbidity rate can refer to either the incidence rate, or the prevalence of a disease or medical condition. This measure of sickness is contrasted with the mortality rate of a condition, which is the proportion of people dying during a given time interval.
