Understanding Fever: Causes, Symptoms, and Management Strategies

A fever, also known as pyrexia or febrile response, refers to a body temperature exceeding the normal range. Typically, a temperature of 100°F or higher signifies a fever.

Fever is generally a symptom rather than a standalone illness, often manageable at home with medications like paracetamol or ibuprofen. Healthcare professionals see it as your body's way of fighting infection, unless other risk factors such as age, medication use, or underlying health conditions are involved.

Infants require special attention; if they show symptoms like cough, cold, or sore throat, consulting a doctor is essential. For babies below 3 months, a temperature of 100°F warrants urgent medical care.

Fever results when the hypothalamus in your brain raises your body's temperature response to infection or inflammation. Common triggers include colds, inflammations, respiratory infections, ear or bladder infections, and sometimes reactions to medication or vaccines.

Other causes may involve hormonal imbalances, blood clots, or autoimmune conditions. The key to diagnosing fever is using a thermometer; a reading above 100°F indicates fever, often accompanied by lethargy or fatigue.

Fever types vary and can hint at underlying health issues:

• Continuous fever: Persistently high throughout the day, often indicating typhoid or pneumonia.
• Intermittent fever: Cycles between high and normal temperatures, typically seen in malaria or septicemia.
• Remittent fever: Fluctuates more than 1°C daily, associated with infections like brucellosis.

Most fevers resolve without medication; however, persistent high temperatures should be evaluated by a healthcare professional. Treatment includes medications like antipyretics, alongside home remedies such as sponge baths and hydration.

If fever persists or is accompanied by concerning symptoms, seek medical attention promptly to determine and treat the underlying cause effectively.
