The differences between the terms signs and symptoms
Objectivity subjectivity vs.
Signs are objective, meaning they are more obvious and observable by doctors and others. Symptoms are subjective, which means that the patient perceives them. The signs usually include bruises, an open wound or a high temperature, while the symptoms include nausea, dizziness, diarrhea and chills.
Patients usually visit a doctor because of their symptoms. Because the symptoms are subjective, the patient should be as descriptive as possible so that the doctor can diagnose the problem. However, since the signs are visible, they will not need the same type of description because the doctor will already be able to notice them.
Because only the patient experiences symptoms, the doctor can not verify them. Symptoms such as fatigue, pain and dizziness are not measurable. Signs, however, may actually be measured by a physician. Increased heart rate, blood pressure and fever are examples of signs that the doctor can measure.
Visibility and Vagueness
Symptoms can be vague to the doctor, so that the signs can not be noticed or anything for the patient means. Signs are objective and visible indication of an illness or injury that the patient knows. These signs will allow the doctor to detect the problem.
