A fever is one of the most common ailments that affect a normal human being. A fever, also known as pyrexia or controlled hyperthermia, occurs when the body's temperature rises above the normal range (97 to 99º F (36 to 37.2º C). This is the body's thermoregulatory set point which rises when there is any faulty mechanism like an infection or disease that affects the body. A low-grade fever usually keeps fluctuating i.e., it has the tendency to rise in temperature and then suddenly fall back down to normal or a low reading. This kind of fever does not rise above 101º F (38.5°C) and is not considered dangerous. The following article will deal with some of the causes of this form of fever and try to get to the root of the same.
There are quite a few conditions that lead to a low-grade fever. Since it is the body's way of dealing with the viruses that cause the infection, anything that threatens the smooth functioning of the body's mechanisms will lead to the same.
The common cough and cold are one of the most common causes of a low-grade fever. With the influx of parasites, viruses, and fungi into the body, the defense mechanism of the body goes into a defense mode and raises the body temperature to kill the invaders.
When there is a wound which causes an abrasion to the upper layer of the skin, many times, the opening in the skin leads to toxic invaders entering the body and causing pus, swelling, reddening of the skin, and thus brings about fever.
Tuberculosis is brought about by a bacterial infection that affects the lungs and is caused by the Mycobacterium tuberculosis bacteria. This leads to symptoms like a chronic cough that is sometimes accompanied by blood, and instances of bloody phlegm along with fever.
Measles, also known as rubeola, is caused by a virus that affects the throat, lungs and bronchial tubes, and the respiratory tract. It is highly contagious and brings in its wake a rash, fever, and sore throat.
This is caused by the rubulavirus and is a very contagious disease. It results in the swelling of salivary glands, pancreas, and sometimes, the ovaries and testes as well. This is a highly contagious disease as well.
Allergies are caused when there is a histamine that enters our body and to protect one from this, the body produces antihistamines. The body also produces pyrogens in response to the allergy that is caused, and a fever and headache is usually brought on.
Among the causes of chronic low-grade fever, stress is also taken as one of the main causes. Stress causes the body to go into overdrive and as a result, there are certain abnormal functions that begin to take place in the body. To deal with this, the body raises its temperature and a fever is brought on.
These are some other causes that could well bring on a low-grade fever.
- Overexposure to sunlight and heat.
- Hormonal imbalance
- Chronic abscess
- Rheumatoid arthritis
- Pelvic Inflammatory Disease (PID)
- Autoimmune diseases
