Fever
(Redirected from Fevers)
A fever, also known as pyrexia, is a temporary increase in body temperature above the normal range. While normal body temperature can vary from person to person, it is typically around 98.6°F (37°C). Although a fever is not a disease in itself, it is usually a sign that the body is fighting an illness or infection. This article provides an overview of the causes, symptoms, and treatment options for fevers.
Causes[edit | edit source]
There are various factors that can cause a fever, including:
- Infections: Most fevers result from viral or bacterial infections, such as the flu, a cold, or a urinary tract infection. The body raises its temperature to make it more difficult for the pathogens to survive and to activate the immune system.
- Medications: Some medicines, including certain antibiotics, blood pressure medications, and anti-seizure medicines, can cause fevers as a side effect.
- Heat illness: Overexposure to high temperatures or excessive physical exertion in hot weather can lead to heat-related illnesses, such as heat exhaustion or heat stroke, which may cause a fever.
- Cancers: Certain types of cancer, like leukemia and lymphoma, can cause fevers.
- Autoimmune diseases: Conditions like lupus, rheumatoid arthritis, and inflammatory bowel disease can lead to fevers due to the immune system attacking the body's own tissues.
- Immunizations: Some childhood vaccinations may cause a mild fever as the body responds to the vaccine.
Symptoms[edit | edit source]
In addition to an elevated body temperature, fevers can cause a range of symptoms, such as:
- Sweating
- Shivering
- Headache
- Muscle aches
- Weakness
- Loss of appetite
- Dehydration
- Increased heart rate
Diagnosis[edit | edit source]
A fever can be diagnosed using a thermometer to measure body temperature. Thermometers can be placed in various locations, including the mouth (oral), ear (tympanic), armpit (axillary), or rectum (rectal).
Treatment[edit | edit source]
The treatment for a fever depends on the underlying cause. In cases of mild to moderate fever, the following measures can help alleviate symptoms:
- Over-the-counter medications: Acetaminophen, ibuprofen, or naproxen can help lower a fever and relieve associated discomfort. Aspirin is an option for adults but should not be given to children with fevers, as it can cause Reye's syndrome, a rare but serious condition.
- Fluid intake: Drinking plenty of fluids, such as water, juice, or broth, can help prevent dehydration caused by fever and sweating.
- Rest: Adequate rest allows the body to focus its energy on fighting the infection or illness causing the fever.
When to Seek Medical Attention[edit | edit source]
It is important to consult a healthcare provider if:
- The fever is unusually high (over 103°F or 39.4°C) or lasts for more than a few days.
- The fever is accompanied by severe symptoms, such as difficulty breathing, chest pain, or a stiff neck.
- The person with the fever is very young, elderly, or has a weakened immune system.
Prevention[edit | edit source]
To reduce the risk of developing a fever, it is essential to take measures to prevent infections, such as:
- Washing hands regularly with soap and water
- Keeping up-to-date with vaccinations
- Maintaining good hygiene practices
- Avoiding close
- contact with individuals who are sick
- Practicing safe food handling and storage
- Staying hydrated and getting adequate rest to maintain overall health
