A haigussümptom is a manifestation or indication of a disease or medical condition. It is an observable or a felt sign that something is wrong within the body. Symptoms can vary widely in their nature, intensity, and duration depending on the underlying illness. They are the subjective experiences of a patient, meaning they are what the person feels or notices, such as pain, nausea, fatigue, or dizziness.

In contrast to signs, which are objective findings that can be measured or observed by a healthcare professional (like a fever, rash, or abnormal blood pressure), symptoms are personal perceptions. For example, while a doctor might measure an elevated body temperature (a sign), the patient experiences this as feeling hot or shivery (a symptom).

Understanding symptoms is crucial for diagnosis. Doctors ask patients about their symptoms to gather information and form a hypothesis about the cause of their illness. A single symptom might be indicative of multiple conditions, while a combination of symptoms often points more specifically to a particular disease. Effective communication between patient and healthcare provider about symptoms helps in accurate diagnosis and the subsequent development of an appropriate treatment plan. The presence, absence, and characteristics of symptoms are key elements in the medical assessment process.
