Fever is the body's natural response to infection or inflammation. Generally, a fever will improve within a few days once the underlying cause is addressed. However, what if a fever recurs without a clear cause? This condition requires attention as it could be a sign of a more serious health problem. Recurrent fevers should not be taken lightly, especially if they occur over a long period of time or are accompanied by other symptoms.
What is Recurrent Fever?
Recurrent fever is a condition where the body temperature increases (≥38°C) and reappears after improving, or occurs intermittently over a certain period.
This fever can last for several weeks or even months, depending on the underlying cause.
Causes of Recurrent Fever
Some conditions that can cause recurring fever include:
1. Chronic Infection
Infections such as tuberculosis (TB), urinary tract infections, or other infections can cause recurring fevers.
2. Autoimmune Diseases
Autoimmune disorders occur when the immune system attacks healthy tissue, triggering inflammation and fever.
3. Immune System Disorders
Disorders of the immune system can make the body more susceptible to repeated infections accompanied by fever.
4. Cancer
Some types of cancer, such as blood cancer, can cause fever that has no clear cause and lasts a long time.
5. Certain Viral Infections
Some viral infections can cause intermittent fever, especially if they have not fully healed.
Symptoms to Watch Out For
Recurrent fever needs to be checked immediately if it is accompanied by:
- Weight loss without cause
- Excessive night sweats
- Easily tired
- Pain in certain parts of the body
- Persistent cough
- Swollen lymph nodes
These symptoms can be an indication of a certain disease that requires medical treatment.
The Importance of Further Investigation
To find out the cause of recurring fever, doctors will usually carry out a series of examinations, such as:
- Blood test
- urine test
- X-ray or radiological examination
- Additional examinations as indicated
A thorough examination helps determine the appropriate diagnosis and therapy.
When Should You See a Doctor?
Immediately consult an internal medicine specialist if:
- Fever lasting more than 3 days without improvement
- Fever often recurs within a few weeks
- Accompanied by other disturbing symptoms
- The body condition is getting weaker
Don't Ignore Recurring Fever
Recurrent fevers are a signal from the body that something needs further investigation. Early treatment is crucial to prevent the condition from becoming more serious.
With proper diagnosis and appropriate therapy, various causes of recurrent fever can be optimally managed, so that health is maintained and daily activities are not disrupted.
