What does subjective symptoms mean

These indicators can be the difference between normal function and dangerous diseases and conditions. Since the s, medical science has come on leaps and bounds in helping physicians clearly identify signs.

A range of devices is now available to help doctors identify and analyze signs that even the patient may not have recognized. During the 20th century, hundreds of new devices and techniques were created to evaluate signs.

Doctors can now see signs they would previously have relied upon patients to describe. By the modern definition, these would have been symptoms but are now classed as signs. Some conditions show no symptoms at all. For example, a person can have high blood pressure for years without knowing, and some cancers have no symptoms until the later, more aggressive stages.

These are known as asymptomatic conditions, and even though the idea of symptoms is often linked to discomfort or abnormal function, a condition without symptoms can be deadly. Many types of infection do not show symptoms. These are known as subclinical infections, and they can be contagious despite not causing noticeable symptoms in the person carrying the infection. The infection can still be transmitted to other people during the incubation period, or the period during which the infectious agent takes hold of the body.

Another danger of subclinical infections is that they can cause complications unrelated to the infection itself. For example, untreated urinary tract infections UTIs may cause premature births.

The first time a person will be aware of many asymptomatic conditions is during a visit to a doctor, normally concerning a different problem.

It is important to undergo regular health checks to identify any underlying problems that may not be obvious. Many cancers are asymptomatic during their early stages. Prostate cancer , for example, does not show symptoms until it has advanced to a certain point. This is what makes some cancers so dangerous, as early treatment is often crucial when treating cancer.

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.

Sometimes, a patient may not notice a sign, and it may not seem relevant. A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives. The sign is objective evidence of disease; a symptom, subjective. Symptoms represent the complaints of the patient, and if severe, they drive him to the doctor's office.

If not severe, they may come to light only after suitable questions. The patient perceives, for example, subjective pains and discomforts [Doctor, I have a bad headache], or disturbances of function [Doctor, I can't move my arm the way I used to], or some simple appearance [Doctor, I have had this rash for the past ten days and I'm worried about it].

But the physician, as a skilled observer, can discern what the patient cannot. He can look, palpate and percuss,. King LS. Signs and Symptoms. Coronavirus Resource Center. Brooks, MD ; Charles N.
