In reference to human beings, "disease" is often used broadly to refer to any condition that causes [[Pain and nociception|discomfort]], [[dysfunction]], [[distress]], [[social problems]], and/or [[death]] to the person afflicted, or similar problems for those in contact with the person. In this broader sense, disease sometimes includes [[injury|injuries]], [[disability|disabilities]], [[disorders]], [[syndrome]]s, [[infection]]s, isolated [[symptom]]s, deviant [[behavior]]s, and atypical [[human variability|variation]]s of structure and function, while in other contexts and for other purposes each of these may be considered its own distinguishable category. |

A disease is an abnormal condition of an organism that impairs the organism's function in whole or in part and is identified by characteristic signs or symptoms. In reference to human beings, "disease" is often used broadly to refer to any condition that causes discomfort, dysfunction, distress, social problems, and/or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, disease sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes each of these may be considered its own distinguishable category.
While many diseases are biological processes with observable alterations of organ function or structure, others primarily involve alterations of behavior associated with an abnormal condition of the mind.
Causes of diseases, both physical and mental are various, including infectious agents such as bacteria and viruses, environmental poisons, genetic defects, poor diet, unhealthy habits like smoking or overeating, physical or mental stress, auto-immune reactions, a combination of these factors, and, from an Eastern perspective, imbalance among the body's systems and organs.
Some diseases are preventable through the exercise of personal responsibility in the pursuit of health and wellness. Among factors important for prevention of such diseases are good nutrition, exercise, stress management, a healthy environment, wise use of medical resources, good human relationships, a positive outlook on life, and having a spiritual or religious dimension to ones life. Alternative and Eastern medical approaches—whether for humans, animals, or plants—place primary emphasis on models and methods of health maintenance while including diseases and their treatment as a subset of that larger medical model.
Pathology is the study of diseases, and nosology is the systematic classification of diseases. The body of knowledge about human diseases and their treatments is the territory of allopathic or Western medicine. The study of diseases affecting domestic animals, wildlife, livestock, and exotic animals is veterinary medicine. Plants as well can suffer from a variety of afflictions such as infection, nutrient deficiency, or deleterious mutation. Plant pathology is the study of diseases affecting plants.
For diseases with known causes, disease prevention is a matter of personal responsibility according to the safety precautions and lifestyle choices one makes. Individuals with a religious orientation tend to emphasize spiritual well-being as a factor in health promotion and disease prevention. Religions recognize various spiritual laws such as to love, to give, and to live for the sake of others, which are important to one's spiritual health. When one is self-centered, one violates such universal principles, leading the body to be more apt to be susceptible to disease. Following such spiritual principles is also fundamental to having good human relationships and a positive attitude in life.
Classifying a condition as a disease is a social act of valuation, and may change the social status of the person with the condition (the patient). Some conditions (known as culture-bound syndromes) are only recognized as diseases within a particular culture. Sometimes the categorization of a condition as a disease is controversial within the culture.
Syndromes, illness, symptoms, and signs
Medical usage sometimes distinguishes a disease, which has a known specific cause or causes (called its etiology), from a syndrome, which is a collection of signs or symptoms occurring together. The distinction between disease and syndrome, however, is ambiguous, as many conditions whose causes have been identified, continue to be referred to as syndromes, while numerous conditions of unknown etiology are referred to as diseases.
Illness, although often used to mean disease, can also refer to a person's perception of personal health, regardless of whether the person in fact may have a disease. A person without any disease may feel unhealthy and believe he has an illness. Another person may feel healthy and believe he does not have an illness even though he may have a disease such as dangerously high blood pressure, which may lead to a fatal heart attack or stroke.
Symptom
The term symptom (from the Greek syn = con/plus and pipto = fall, together meaning co-exist) has two similar meanings in the context of physical and mental health:
- Strictly, a symptom is a sensation or change in health function experienced by a patient. Thus, symptoms may be loosely classified as strong, mild, or weak. In this medically-correct sense of the word, a symptom is a subjective report, as opposed to a sign, which is objective evidence of the presence of a disease or disorder. Examples of symptoms are fatigue/tiredness, pain, or nausea. The symptom that leads to a diagnosis is called a cardinal symptom. In contrast, elevated blood pressure, or abnormal appearance of the retina, would be a medical sign indicating the nature of the disease.
- A symptom may loosely be said to be a physical condition that shows one has a particular illness or disorder (see Longman 1995). An example of a symptom in this sense of the word would be a rash. Such a visible symptom could also be considered to be a sign.
A sign or symptom, then, is not necessarily defined by its nature, but rather by who observes it. The same feature may be noticed by both doctor and patient, and so is at once both a sign and a symptom. Some features, such as pain, can only be symptoms. A doctor can not feel a patient's pain (unless he is the patient). Others can only be signs, such as a blood cell count measured by a doctor in his/her laboratory.
Some symptoms (e.g. nausea) occur in a wide range of disease processes, whereas other symptoms are fairly specific for a narrow range of illnesses: for example, a sudden loss of sight in one eye has only a very limited number of possible causes. Some symptoms can be misleading to patients or the medical practitioner caring for them. For example, inflammation of the gallbladder quite often gives rise to pain in the right shoulder, which might (quite reasonably) lead a patient to attribute the pain to a non-abdominal cause such as muscle strain, rather than the real cause.
Transmission of disease
Some diseases, such as influenza, are contagious or infectious, and can be transmitted by any of a variety of mechanisms, including coughs and sneezes, sexual transmission, by bites of insects or other carriers of the disease, from contaminated water or food, and so forth.
Other diseases, such as cancer and heart disease, are not considered to be due to infection, although microorganisms may play a role.
Social significance of disease
The identification of a condition as a disease, rather than as simply a variation of human structure or function, can have significant social or economic implications. The controversial recognitions as diseases of post-traumatic stress disorder, also known as "shell shock"; repetitive motion injury or repetitive stress injury (RSI); and Gulf War syndrome have had a number of positive and negative effects on the financial and other responsibilities of governments, corporations, and institutions towards individuals, as well as on the individuals themselves.
A condition may be considered to be a disease in some cultures or eras but not in others. Oppositional-defiant disorder, attention-deficit hyperactivity disorder (ADHD), and, increasingly, obesity are conditions considered to be diseases in the United States and Canada today, but were not so considered decades ago and are not so considered in some other countries. Lepers were a group of afflicted individuals who were historically shunned and the term "leper" still evokes social stigma. Fear of disease can still be a widespread social phenomenon, though not all diseases evoke extreme social stigma.

Exercise has been shown to reduce risks for diseases such as heart disease, high blood pressure, diabetes, obesity, and colon cancer. In addition, exercise has been shown also to reduce risks for some mental diseases, such as depression.
Good stress management can also reduce the risk of and/or prevent disease. Stress can be a contributing or even primary factor to a number of pathologies or combination of pathologies including cardiovascular disease, mental diseases, internal organ diseases, or musculoskeletal diseases.
