Fever

Fever is a temporary rise in body temperature above the normal range (37°C/98.6°F), usually a sign that the body's immune system is fighting an infection. It is often accompanied by chills, sweating, headache, and muscle aches, and may fluctuate over the day depending on the underlying cause. Most fevers in adults are short-lived and resolve within a few days as the body clears the underlying illness. The most common causes include: Viral infections (flu; common cold); bacterial infections; urinary tract infections.

Fever becomes an emergency when it is unusually severe, sudden in onset, accompanied by other serious symptoms (chest pain, difficulty breathing, fainting), or occurs in vulnerable individuals such as infants, the elderly, or people with serious chronic conditions.

Diagnosis of Fever begins with a detailed medical history and physical examination of the whole body. Your doctor may order blood tests, urine analysis, imaging studies (X-ray, ultrasound, MRI), or refer you to a specialist depending on suspected causes. Early diagnosis leads to faster, more effective treatment.

Mild cases of Fever can often be managed with self-care: Rest; drink plenty of fluids to stay hydrated; use a lukewarm sponge bath to help lower temperature. However, if symptoms are severe, persistent, or worsening, always seek medical attention rather than relying solely on home remedies.

Fever is typically classified as acute. Acute forms usually resolve within a few days to weeks with appropriate care. Chronic or recurrent fever may persist for months and requires longer-term management by a healthcare professional.

You should see a doctor if: Seek immediate medical attention if fever exceeds 103°F (39.4°C); lasts more than 3 days; or is accompanied by severe headache. Early evaluation by a healthcare professional ensures an accurate diagnosis and prevents complications.
