"Symptoms" redirects here. For other uses, see Symptom (disambiguation).
A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls",[1] from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease. A symptom is subjective,[2] observed by the patient,[3] and cannot be measured directly,[4] whereas a sign is objectively observable by others. For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic.
The term is sometimes also applied to physiological states outside the context of disease, as for example when referring to "symptoms of pregnancy".

Types
Symptoms may be chronic, relapsing or remitting. Asymptomatic conditions also exist (e.g. subclinical infections and, sometimes, high blood pressure).
Constitutional or general symptoms are those related to the systemic effects of a disease (e.g., fever, malaise, anorexia, and weight loss). They affect the entire body rather than a specific organ or location.
The terms "chief complaint", "presenting symptom", "iatrotropic symptom", or "presenting complaint" are used to describe the initial concern which brings a patient to a doctor. The symptom that ultimately leads to a diagnosis is called a "cardinal symptom".
Non-specific symptoms are self-reported symptoms that do not indicate a specific disease process or involve an isolated body system. For example, fatigue is a feature of many acute and chronic medical conditions, which may or may not be mental, and may be either a primary or secondary symptom. Fatigue is also a normal, healthy condition when experienced after exertion or at the end of a day.
Positive and negative
In describing mental disorders,[5][6] especially schizophrenia, symptoms can be divided into positive and negative symptoms.[7]
- Positive symptoms are symptoms present in the disorder but not normally experienced by most individuals. It reflects an excess or distortion of normal functions (i.e., experiences and behaviors that have been added to a person’s normal way of functioning).[8] Examples are hallucinations, delusions, and bizarre behavior.[5]
- Negative symptoms are functions that are normally found in healthy persons, but that are diminished or not present in affected persons. Thus, it is something that has disappeared from a person’s normal way of functioning.[8] Examples are social withdrawal, apathy, inability to experience pleasure and defects in attention control.[6]
Possible causes
Some symptoms 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 a significantly smaller number of possible causes than nausea does.
Some symptoms can be misleading to the patient or the medical practitioner caring for them. For example, inflammation of the gallbladder often gives rise to pain in the right shoulder, which may understandably lead the patient to attribute the pain to a non-abdominal cause such as muscle strain.
Symptom versus sign
A symptom can more simply be defined as any feature which is noticed by the patient. A sign is noticed by other people. It is not necessarily the nature of the sign or symptom which defines it, but who observes it.
A feature might be a sign or a symptom - or both - depending on the observer(s). For example, a skin rash may be noticed by either a healthcare professional as a sign, or by the patient as a symptom. When it is noticed by both, then the feature is both a sign and a symptom. In lists of features to expect in the history and physical examination, "rash" may be listed under both (constituting a symptom in the former, a sign in the latter).
Some features, such as pain, can only be symptoms, because they cannot be directly observed by other people. Other features can only be signs, such as a blood cell count measured in a medical laboratory, which most patients have no way to observe independently.
