Definition of Symptom

Medically reviewed by Min Clinic Staff | Updated: January 2026

Symptom: Any subjective evidence of disease. In contrast, a sign is objective. Blood coming out a nostril is a sign; it is apparent to the patient, physician, and others. Anxiety, low back pain, and fatigue are all symptoms; only the patient can perceive them.
