Overview

Fever is generally a medical condition characterized by an elevation of body temperature above the normal range of 36.5-37.5 degree Celsius due to an increase in the temperature regulatory set-point. When body temperature increases, there is a feeling of cold despite an increasing body of temperature.

Signs and Symptoms

The most common fever symptoms are:

  • Shivering
  • Headache
  • Lethargy
  • Feeling dull
  • Sleepiness
  • Inability to focus

Causes

Fever is generally the result of an immune response by your body to a foreign invader. These foreign invaders may include viruses, bacteria, fungi, drugs, or other toxins.

Fever is a common symptom of most infections. In children, immunizations or teething may cause low-grade fever. Autoimmune disorders, medication reactions, seizures, or cancer may also cause fevers.

Treatment

Generally, if fever doesn’t cause any discomfort, the fever itself should not be treated. Your doctor may prescribe some fever-reducing medications to reduce the body temperature.
