Fever | Causes, Symptoms, Types, Diet & Home Remedies

What is Fever ?

Fever is a common disease. Often people have fever for one reason or the other. The normal human body temperature is 98.6o Fahrenheit. This condition is medically known as pyrexia or hyperthermia. When the temperature of the body starts increasing more than the normal condition, then that condition is called fever. Howevere , sometimes it may happen that your temperature may increase and this fever can become a serious problem. 

Fever occurs in both children and adults. Fever usually occurs when the immune system detects the presence of an infection-causing pathogen in the body. The immune response involves increasing the body temperature to eliminate the pathogen. Many micro-organisms such as bacteria, viruses, fungi and other types of microbes enter the human body, almost every day. The immune system usually fights off these micro-organisms, which keeps them from causing any major problems within the body. However, there may be times when the immune system cannot fight them all and eliminate them from the body. When a person’s immune system fails to stop these harmful viruses, they usually cause infections in the body. Later it presents in the body as a fever. Therefore the term viral fever can be used for a variety of infections caused by viruses. 

Many other factors can also affect body temperature. Eating, exercising, sleeping, time of day, etc. can cause slight changes in body temperature. A slight increase in body temperature or sometimes a fever usually goes away on its own without any medication. However, a very high rise in body temperature can be a symptom of a serious medical condition. A person with high or recurring fever should consult a physician immediately. Let us know in this article the causes, symptoms, diagnosis and treatment of fever.

Diagnosis of Fever

Diagnosis of fever is generally a simple process. In which the patient’s temperature is taken, and if the temperature is above a level, then it is called fever. While measuring the temperature, keep in mind that the affected person is in a state of rest. Because any type of physical activity can increase our body temperature. A person is said to be suffering from fever when :

  • The temperature in the mouth exceeds 37.7 °C (99.9 °F).
  • The temperature in the rectum (anus) is greater than 37.5-38.3 degrees centigrade (100-101 Fahrenheit).
  • The temperature under the arm or inside the ear is greater than 37.2 °C (99 Fahrenheit).
