Fever Discharge Information

What is a fever?

Fever is defined as a body temperature that is 1 or more degrees higher than normal. Normal body temperature varies from person to person, by age, by the time of day, and by the part of the body where it is measured. Other factors such as strenuous exercise, medicines, or even excitement can also affect body temperature.

Different types of thermometers are available to measure your temperature in different parts of your body. For example, there are thermometers that measure temperature in the mouth, ear, armpit, or rectum or on the forehead. Temperatures measured in the different areas may be different by one-half to 1 degree.

Fever can be a sign that the body is fighting an infection or that you have a medical problem, such as dehydration, a hormone disorder, certain cancers, an immune system problem, or a reaction to certain medicines that you are taking. Most often, the fever is associated with other symptoms of illness. Sometimes, the cause of the fever may not be known.

How can I take care of myself when I go home?

How long it takes to get better depends on the cause of your fever, your treatment, how well you recover, your overall health, and any complications you may have.
