Fever is a common condition that can arise due to various factors such as an infection, inflammation, or injury. It is an evolutionarily conserved response by the body to a stressor, which activates the immune system and promotes the healing process. However, fever can also be a sign of a serious underlying condition and requires medical attention. In this article, we will discuss the common symptoms associated with a fever and how to identify them.
What is fever?
Fever is a rise in body temperature above the normal range. In humans, the normal body temperature ranges between 36.5°C (97.7°F) and 37.5°C (99.5 °F). Fever is defined as a body temperature greater than 38°C (100.4°F). It is a common condition and affects people of all ages.
Common symptoms of fever
Fever is a symptom of an underlying condition and is often accompanied by other symptoms. The common symptoms associated with fever are:
1. High body temperature
The most common symptom of fever is a high body temperature. The body temperature can rise rapidly and may exceed 40°C (104°F) in some cases.
2. Shivering
When the body temperature rises, the muscles start to contract involuntarily, causing shivering. Shivering is the body’s way of generating extra heat to raise the body temperature.
3. Sweating
When the body temperature rises, the sweat glands secrete sweat to cool the body down. Sweating is a common symptom of fever.
4. Headache
Headache is a common symptom associated with fever. The rise in body temperature can cause headaches, which can range from mild to severe.
5. Muscle aches
Fever can cause muscle aches and fatigue. The muscles may feel sore and tender to the touch.
6. Fatigue
Fever can cause fatigue, which is a feeling of exhaustion or weakness. The body is expending energy to fight the underlying condition, which can lead to fatigue.
7. Loss of appetite
Fever can cause a loss of appetite. The body may divert energy towards fighting the underlying condition, causing a reduced desire to eat.
8. Irritability
Fever can cause irritability, which is a feeling of restlessness or agitation. This may be due to the discomfort caused by the fever.
9. Dehydration
Fever can cause dehydration, which is a condition where the body loses more fluids than it takes in. This can lead to dry mouth, thirst, and dark urine.
10. Rapid heartbeat
Fever can cause an increase in heart rate. The heart beats faster to circulate more blood to the body, which helps to regulate the body temperature.
Causes of fever
Fever can be caused by various factors, including:
1. Infections
Infections such as viral, bacterial, and fungal infections can cause a fever. The fever is the body’s way of fighting the infection.
2. Inflammatory conditions
Inflammatory conditions such as rheumatoid arthritis and lupus can cause a fever. Inflammation is a natural response by the body to injury or infection, and can cause a fever.
3. Medications
Some medications such as antibiotics and antihistamines can cause a fever as a side effect.
4. Heat exhaustion
Heat exhaustion is a condition where the body overheats due to exposure to high temperatures. This can cause a fever.
5. Cancer
Cancer can cause a fever, especially if it has spread to other parts of the body.
Diagnosing a fever
A fever can be diagnosed by taking a body temperature reading. The most accurate way to take a temperature is by using a digital thermometer. The thermometer should be placed under the tongue, in the ear, or in the rectum for accurate readings.
When to seek medical attention
Most fevers are harmless and go away within a few days. However, in some cases, a fever can indicate a serious underlying condition and requires medical attention. You should seek medical attention if you:
1. Have a high fever
A high fever can be a sign of a serious underlying condition and requires medical attention.
