Causes of undiagnosed fevers

• Infections: Such as common cold, malaria, dengue, typhoid, chikungunya, tuberculosis, pneumonia, urine infections meningitis, and abscess to name a few.
• Viruses: Some viruses, such as Epstein-Barr virus and cytomegalovirus, can cause fever apart from the common ones like influenza.
• Autoimmune disorders: These conditions occur when the body’s immune system attacks healthy tissue. Examples include lupus and rheumatoid arthritis.
• Cancer: In some cases, fever can be an early symptom of cancer.

What to do if you have an undiagnosed fever?

If you have a fever that lasts for more than a few days or is accompanied by other symptoms, it is important to see a doctor. Your doctor will likely ask about your medical history and perform a physical exam. They may also order tests, such as blood tests, imaging studies, and cultures.

In some cases, it may take several weeks to determine the cause of an undiagnosed fever. This is because some tests may take time to come back, and your doctor may need to evaluate systematically to rule out a number of possible causes.

Basic tips:

• Get adequate rest
• Drink plenty of fluids
• Eat a healthy diet
• Get regular exercise
• Manage stress
• Get enough sleep
• See your doctor for regular checkups, and if you develop fever or if you experience other concerning symptoms

By following these tips, you can help to boost your immune system and reduce your risk of developing an undiagnosed fever.

Undiagnosed fevers can be a source of stress and anxiety. However, it is important to remember that there are many possible causes of fever, and not all of them are serious. By working with your doctor, you can find the answers you need and get the treatment you deserve.
