Known medically as pyrexia, elevation of body temperature above the average level of 37 degrees in the mouth and 0.6 degrees lower in the axilla (armpit). A fever can be accompanied by symptoms such as headache, thirst, sweating, shivering, unusually fast breathing, and a flushed face. Delirium or confusion occasionally arises with a fever, particularly in elderly people. A high fever can cause seizures in a child under five years of age.
Many fevers are caused either by viral infection, such as influenza or bacterial infections, such as tonsillitis. In these cases, proteins called pyrogens are released when the white blood cells fight the microorganisms that are responsible for the infection. Pyrogens act on the temperature-controlling centre in the brain, causing it to raise the temperature of the body in an attempt to kill the invading microorganisms.
Fever can also arise in other conditions where infection is not present. These conditions include thyrotoxicosis (a condition that occurs from over activity of the thyroid gland), dehydration, lymphoma (a tumour of the lymphatic system), and myocardial infarction (heart attack).
Drugs such as aspirin, and other nonsteroidal anti-inflammatory, or paracetamol can be administered to diminish fevers caused by infections. Aspirin should not be given to a child under the age of sixteen, except on the instruction of a doctor, nor should it be consumed by women who are pregnant or breast-feeding. Otherwise treatment is directed at the underlying cause; for example, antibiotic drugs are given to treat a bacterial infection. These drugs do have very strong side effects such as causing damage to you liver, kidney’s and can cause stomach ulcers in the case of asprin so they should not be used for any great length of time and one would need to get to the root of the underlying problem in a natural way.
