How to Manage Fever of Unknown Origin? Complete Guide
Fever is the body’s natural defence mechanism — but when it lingers with no known cause, it can be worrying. This condition is medically known as Fever of Unknown Origin (FUO). It’s not just a difficult temperature spike — it could be a sign of a deeper issue, especially if it lasts for more than three weeks despite initial investigations.
At Sun Speciality Clinics – FeVac Centre, we often see patients struggling to get to the root of such fevers. In this guide, let’s understand how to approach, diagnose, and manage Fever of Unknown Origin — and when to seek help from a Fever Specialist in Coimbatore like Dr. A. Murali.
What is Fever of Unknown Origin (FUO)?
Fever of Unknown Origin refers to a fever that:
- Persists for more than 3 weeks,
- Has a temperature of 38.3°C (101°F) or higher,
- And remains undiagnosed after one week of hospital evaluation.
Fever of Unknown Origin is not a disease but a symptom — and it could be caused by infections, autoimmune diseases, cancers, or even certain medications.
Common Causes of FUO:
While the causes vary, the most common triggers include:
- Infections (like tuberculosis, HIV, endocarditis)
- Autoimmune disorders (such as lupus, vasculitis)
- Cancers (like lymphomas, leukaemia)
- Undiagnosed tropical diseases, particularly in South India
With Coimbatore’s climate and rising incidences of viral and tropical infections, it’s important to get evaluated by a qualified Fever Specialist in Coimbatore if your fever persists without explanation.
