What is a Fever?
Your body temperature is controlled by the hypothalamus, a part of your brain. The hypothalamus can reset your body’s temperature in response to illness, infection, or other causes. A fever is a sign of something going on inside your body.
Fevers aren’t generally dangerous but it is worth talking to your doctor if you have any concerns.
- A temperature of 103 is considered to be the ideal adult temperature
- Very young infants (under 3 Months) have a rectal temperature of 100.4 or more. Call your doctor immediately or go to an urgent care center.
- A 3-3-6-month-old child has a higher-than-normal rectal temperature, is irritable, or sleepy. Call your doctor immediately
- A 3-month-old child has a rectal temperature of 102 or more
- A fever of more than 102 degrees for at least one day in a 6- to 24-month-old child, or other symptoms like a cough or diarrhea, is a sign that the child has a fever.
- If a child is older than 2, he or she has a fever. It can be severe and include rash, real discomforts, irritability or listlessness.
- A seizure occurs in an infant or child
- A child could experience seizures if they have a temperature above 104
- A fever that develops after someone has been exposed to high temperatures can be an indication of heat stroke.
- Even if you take the prescribed doses of ibuprofen, your fever does not go away.
- You have been in touch with someone with COVID-19
Fevers can be a sign of an infection or illness. These symptoms may also be present if you are suffering from an infection.
- Shivering or chills
- Feeling weak
- Being irritable
- Losing your appetite
- Being dehydrated
Fever can indicate a variety of health conditions that may need medical attention.
Fever is caused by infections like colds or stomach bugs (gastroenteritis). Others include:
- Infections to the ear, bladder, bladder, kidney, skin, lung, skin, and throat
- Heat exhaustion
- Conditions that can cause inflammation such as rheumatoidarthritis
- Side effects of medication
- Vaccines, immunizations
- Blood clots
- Autoimmune conditions like Lupus and IBS (inflammatory bowel disease) can be caused by autoimmune disorders.
- Hyperthyroidism and other hormone disorders are examples.
- Illicit drugs like cocaine and amphetamines are illegal
- A mild, low-grade fever can occur when babies are tethered (not more than 101 degrees).
A fever can be easily measured with a thermometer. However, it can be difficult to determine the cause. Your doctor will also ask you about your medical history, including any medications and recent travels to areas where there are infections. For example, a malaria infection can cause a fever that usually comes back. There are certain areas in the United States that are particularly susceptible to Lyme disease or Rocky Mountain spotted fever.
You may experience a “fever with unknown origin” from time to time. Sometimes, you may experience a “fever of unknown origin”. This could be due to an uncommon or undiagnosed condition, such as cancer, connective tissue disorders, chronic infections, or other problems.
Fever is often associated with discomfort. Most people feel better if a fever can be treated. You may need medical treatment depending on the cause of the fever. Experts believe that fever is a natural defense against infection. However, there are many other causes of fever that are not infectious.
The cause of the fever will determine the treatment. A bacterial infection, such as strep-thorphritis, would require antibiotics.
Over-the-counter medications such as acetaminophen or nonsteroidal anti-inflammatory drug such as naproxen and ibuprofen are the most commonly used treatments for fever. Aspirin is linked to Reye’s syndrome, which can be fatal for children and teens.
There are several ways to lower your fever at home:
- Drinking lots of fluids like water, broth, juices, or a rehydration beverage.
- Take a lukewarm shower
- Keep cool by wearing lightweight clothing and bedding.
