A fever is higher-than-normal body temperature. It is a symptom caused by a variety of illnesses.
Every one of us has experienced the wave of chills and exhaustion that a fever causes. Fever usually occurs in response to an infection or inflammation. However, many other causes are possible, including drugs, poisons, cancer, heat exposure, injuries or abnormalities to the brain, or disease of the endocrine (hormonal) system.
A fever rarely comes without other symptoms. It is often accompanied by specific complaints, which may help to identify the illness causing the fever. This can help the doctor determine which treatment is necessary.
