Selfdiagnosis

Self-diagnosis refers to the process of identifying a health condition by oneself, based on symptoms, experiences, and information from various sources, without or before consulting a healthcare professional. It can occur in everyday life when mild symptoms arise, or in response to access difficulties, cost, or privacy concerns.

People may use symptom checkers, medical websites, mobile apps, social networks, or personal experiences to form an impression of possible conditions. Information quality varies; reputable sources include professional medical organizations, peer-reviewed literature, and clinical guidelines, while misinformation and anecdotal claims can mislead. Self-assessment may lead to triage decisions such as over-the-counter remedies, home monitoring, or seeking in-person care.

Risks include inaccurate conclusions, unnecessary worry or false reassurance, delayed diagnosis, inappropriate treatment, privacy concerns, and overreliance on non-professional sources. Complex or serious symptoms require professional evaluation; self-diagnosis is not a substitute for medical testing, differential diagnosis, or treatment planning.

When to seek help: new, severe, or worsening symptoms; red flags such as chest pain, trouble breathing, sudden weakness, speech difficulties, high fever, or severe pain. For ongoing or unclear symptoms, consult a clinician. When discussing results with a clinician, it can help to share consulted sources and a concise summary of observed symptoms to aid evaluation.
