Prolonged Fever

A fever that persists for more than a week without a clear explanation, sometimes called fever of unknown origin. Body temperature may fluctuate throughout the day and is often accompanied by fatigue, poor appetite, and weight loss as the underlying cause continues undetected. The most common causes include: Tuberculosis; typhoid fever; urinary tract or other hidden infections; autoimmune diseases like lupus.

Prolonged 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 Prolonged 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 Prolonged Fever can often be managed with self-care: Stay well hydrated; rest adequately; and monitor temperature at regular intervals to track the pattern. Because prolonged fever usually has an underlying cause that needs proper diagnosis and specific treatment. However, if symptoms are severe, persistent, or worsening, always seek medical attention rather than relying solely on home remedies.

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

You should see a doctor if: See a doctor promptly if fever lasts more than five to seven days; is accompanied by significant weight loss; night sweats. Early evaluation by a healthcare professional ensures an accurate diagnosis and prevents complications.
