Difference Between Signs And Symptoms

We often use the terms ‘signs’ and ‘symptoms’ interchangeably, which is wrong. They are two very different things which we must use correctly. It is quite common for a non-medical person to get these words wrong, but this article will help clear it. In other words, signs are something which doctors and other people observe. On the other hand, symptoms are something a patient notices on their word. While it is true that these terms are interrelated but there is a huge difference between signs and symptoms. One of the main difference is in terms of features. For instance, a doctor prescribes blood tests, x-ray, checking pulse rate, which indicate the signs of disease. And, the patient who feels body pain, fatigue, headache can term them as symptoms.

Definition of Sign

If we look at the general meaning of a sign, it will mean to denote or provide information about something. However, medically, the sign means to gain actual information about a certain disease or illness.

The doctors or health care professionals ask for symptoms from the patient as well as use other measurable methods like blood test, pulse rate check, X-ray and more. One can observe signs by feeling, hearing or seeing them and it is the objective evidence of disease.

For instance, swelling, bleeding, fractures, these all are examples of signs. Thus, signs physically demonstrate a disease which others are able to detect.

Definition of Symptom

Symptoms are something which only the patient can experience. In other words, it is like a type of report which the patient provides to the doctor. Consequently, based on that, the doctor diagnoses the patient.

Unlike signs which are objective, symptoms are subjective as only the person can feel it. For instance, headache, nausea, shivering, body ache, muscles fatigue, and more and all examples of symptoms.

In fact, one can also consider symptoms to be an indication of certain diseases. Most importantly, they are not visible to others. Regardless, it is important to not ignore them and take them seriously. If you notice any, it is advisable to consult a physician.
