A disease or medical condition is an abnormal condition of an organism that impairs bodily functions, associated with specific symptoms A symptom is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured and signs A medical sign is an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination of a patient.[1][2][3] It may be caused by external factors, such as infectious disease An infectious disease is a clinically evident illness resulting from the presence of pathogenic microbial agents, including pathogenic viruses, pathogenic bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions. These pathogens are able to cause disease in animals and/or plants. Infectious pathologies are also, or it may be caused by internal dysfunctions, such as autoimmune diseases Autoimmune diseases arise from an overactive immune response of the body against substances and tissues normally present in the body. In other words, the body actually attacks its own cells.The immune system mistakes some part of the body as a pathogen and attacks it. This may be restricted to certain organs or involve a particular tissue in.
In human beings, "disease" is often used more broadly to refer to any condition that causes pain Pain is the unpleasant and aversive feeling common to such experiences as stubbing a toe, burning a finger, putting iodine on a cut and bumping the "funny bone". The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or, dysfunction, distress, social problems Social issues are matters which directly or indirectly affect many or all members of a society and are considered to be problems, controversies related to moral values, or both, and/or death Death is the termination of the biological functions that define a living organism. It refers both to a particular event and to the condition that results thereby. The true nature of the latter has, for millennia, been a central concern of the world's religious traditions and of philosophical enquiry. Belief in some kind of afterlife or rebirth is to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries Injury or bodily injury is damage or harm caused to the structure or function of the body caused by an outside agent or force, which may be physical or chemical, and either by accident or intentional. Personal Injury also refers to damage caused to the reputation of another rather than physical harm to the body. A severe and life-threatening, disabilities The World Health Organization defines Disability as follows: "Disabilities is an umbrella term, covering impairments, activity limitations, and participation restrictions. An impairment is a problem in body function or structure; an activity limitation is a difficulty encountered by an individual in executing a task or action; while a, disorders, syndromes In medicine and psychology, the term syndrome refers to the association of several clinically recognizable features, signs , symptoms (reported by the patient), phenomena or characteristics that often occur together, so that the presence of one feature alerts the physician to the presence of the others. In recent decades the term has been used, infections An infection is the detrimental colonization of a host organism by a foreign species. In an infection, the infecting organism seeks to utilize the host's resources to multiply, usually at the expense of the host. The infecting organism, or pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss, isolated symptoms A symptom is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured, deviant behaviors Behavior or behaviour refers to the actions or reactions of an object or organism, usually in relation to the environment. Behavior can be conscious or subconscious, overt or covert, and voluntary or involuntary, and atypical variations Human variability, or human variation, is the range of possible values for any measurable characteristic, physical or mental, of human beings. Differences can be trivial or important, transient or permanent, voluntary or involuntary, congenital or acquired, genetic or environmental. This article discusses variabilities that characterize a person of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories.
