Symptoms are subjective, meaning that other people only know about them if informed by the individual with the condition. This MNT Knowledge Center article will look at the implications of signs and symptoms as well as their history. The piece will also introduce the different types of sign and symptom and their uses in medicine.
Any objective evidence of a disease, such as a skin rash or a cough, is a sign. A doctor, family members, and the individual experiencing the signs can identify these. However, less obvious breaks in normal function, such as stomachache, lower back pain, and fatigue, are symptoms and can only be recognized by the person experiencing them.
A medical sign is a physical response linked medical fact or characteristic that is detected by a physician, nurse, or medical device during the examination of a patient. They can often be measured, and this measurement can be central to diagnosing a medical problem.
