Symptom evaluation is the process of assessing a patient's signs and symptoms to determine the underlying cause of their health issues. This involves gathering detailed information about the symptoms, including their duration, intensity, and any factors that may worsen or alleviate them. Healthcare professionals often use questionnaires and interviews to collect this information. Once the symptoms are documented, healthcare providers analyze the data to identify potential diagnoses. This may involve physical examinations, laboratory tests, or imaging studies. The goal of symptom evaluation is to create an accurate picture of the patient's health, guiding effective treatment options and improving overall care.
