What Causes Fever?

Q:
What causes fever?

A:
Fever occurs when a part of the brain called the hypothalamus shifts the set point of your normal body temperature upward. When this happens, you may feel chilled and add layers of clothing or you may start shivering to generate more body heat. This eventually results in a higher body temperature.

There are numerous different conditions that can trigger fevers. Some possible causes include:

  • blood clots
  • extreme sunburn
  • food poisoning
  • infections, including the flu, common cold, and pneumonia
  • some immunizations, such as diphtheria or tetanus (in children)
  • some inflammatory diseases, including rheumatoid arthritis and Crohn’s disease
  • some medications, including antibiotics
  • teething (in infants)

If you go to see your doctor, he or she will probably perform a physical examination and medical tests. This will help them determine the cause of the fever and an effective course of treatment.
