A symptom is a sign made by the body in response to a disease or condition. Diseases are typically responsible for many different symptoms, which can be identical from one disease to the next, hence the need to cross-check all the symptoms and conduct supplementary examinations in order to more meticulously investigate the symptoms and their suspected causes. There are, nevertheless, some diseases that manifest with no symptoms whatsoever, which are called asymptomatic diseases. A symptom is generally distinguished from a clinical sign in that the symptom is subjective, as it is described by the patient, and the clinical sign objective, as it is reported by the doctor.
