Fever in Adults – An Overview
Fever also is known as pyrexia, is a situation where body temperature is higher than normal. This symptom can be caused by a large variety of illnesses.
Anyone within any age range may have it. That notwithstanding, fever in adults is, however, been put into focus.
Exhaustion and chills caused by a fever are being experienced by everyone. It often manifests in reaction to infection such as viruses that bring cold, flu, strep throat bacterial infection.
Others are inflammation that occurs with tissue injury or disease. However, there are other many causes of fever, which include drugs, poisons, heat exposure, injuries or abnormalities to the brain. As well as the disease of the endocrine (hormonal or glandular) system.
It is possible for a fever to come without other symptoms. Fever is mostly followed by particular complaints, which may help to identify the illness causing it. This can make it easy for the doctor to come up with a
Body Temperature in Adults
Depending on a different individual, normal body temperature may vary at any time of day, and weather as well. For many adults, a temperature of 98.6F or 37C or Celsius is considered to be normal.
Hypothalamus is the part of the brain that controls the temperature. It functions as a thermostat for the body. It is also responsible for maintaining a normal temperature.
This is processed through heating mechanisms, such as shivering and increased metabolism. Other processes include, cooling mechanisms, such as sweating and dilating blood vessels close to the skin.
Fever usually come-up in the body when the immune response is triggered by pyrogens, which is a fever-producing substance. Pyrogens is usually originated from a source outside the body.
It stimulates the production of additional pyrogens in the body. There is an increase in the temperature setpoint when the pyrogens alert the hypothalamus. Hence, the body begins to shiver in response and the blood vessels also constrict.
At this point, we get under the covers in an attempt to reach the new temperature that is higher than normal. More so, the body is capable of producing other pyrogens and this is usually a response to inflammation.
This process that takes place in the body is referred to as cytokines also known as endogenous pyrogens.
Fever producing substances known as pyrogens from outside the body and these include the following:
The Measurement of Body Temperature
There are different points through which the body temperature is measured. The body temperature is usually measured with a thermometer which is inserted on or into the rectum, mouth, under the armpit, skin, or ear.
A major and most common way of measuring body temperature has always been with a mercury thermometer. In recent times, because of glass breakage and the possibility of subsequent mercury contamination, many countries now use digital thermometers.
This enables temperature measurement from all the body regions in the above list. Also, you can use disposable sensitive temperature strips to measure the skin temperature
In adults, oral temperature measurement is most commonly used. In another instance, the rectal temperatures are known to be the most accurate because environmental factors that increase or decrease temperature measurements. This to a very large extent have the least effect on the rectal area. The variation in the measurement of rectal temperatures, when compared to oral temperatures taken at the same time, is about 0.6 C higher. Consequently, an accurate measurement of body temperature of 38 C or above is considered to be a “fever” and the person has a febrile illness.
Some of the new alternatives include a temperature-sensitive infrared device that measures the temperature in the skin. This work by simply rubbing the sensor of the device on the body. You can buy these devices in most pharmacies
