symptomer

Symptomer are subjective experiences described by a patient that indicate a deviation from normal function. They are distinguished from signs, which are objective findings observed by a clinician through examination or tests. Symptoms can alert clinicians to disease processes, but they require interpretation in the context of history, physical examination, and diagnostic results.

Symptoms vary in duration, onset, intensity and localization. They can be acute (short-term) or chronic (long-lasting), local (affecting a specific area) or systemic (involving the whole body). Common ways to characterize symptoms include location, quality or character (sharp, dull, burning), severity, timing, and aggravating or alleviating factors.

In medical practice, symptom assessment starts with patient history. Clinicians summarize reported symptoms and use them to generate differential diagnoses, guide testing, and monitor response to treatment. Patient-reported outcomes and symptom checklists are increasingly used in research and routine care to quantify burden and track change over time.

Examples of symptoms include pain, fever, cough, fatigue, nausea, dizziness, and rash. Some symptom patterns may indicate urgent conditions requiring prompt evaluation, such as chest pain suggesting possible cardiac or pulmonary causes, or sudden weakness with facial droop suggesting stroke. Red flags warrant timely medical attention.

While symptoms provide essential information, they are subjective and may vary according to individual perception, mood, and language. Corroboration with signs, tests and clinical judgment is important for accurate diagnosis. Patients are encouraged to report all relevant symptoms and changes, even if they seem minor.
