A fever is not just a rise in body temperature but a signal from your body that something requires attention, whether it’s an infection, an inflammatory condition, or another health issue. While most fevers are harmless and resolve quickly, it’s important to monitor the symptoms and seek medical advice if necessary.
A fever occurs when your body temperature rises above the normal range. It’s not an illness in itself but a symptom indicating an underlying health condition. Typically, a fever signals that the body is responding to an unusual process, such as an infection. While fevers can cause discomfort in both children and adults, they are usually not a cause for alarm and often resolve within a few days. However, in some cases, the underlying condition may require timely medical attention.
If you have a fever, it’s essential to identify the cause. You can book an online consultation with experienced general physicians in Bangalorethrough Apollo for reliable advice. Continue reading to explore the common symptoms and potential causes of fever.
Symptoms of a Fever
The average body temperature typically falls between 97.5°F and 98.9°F (36.4°C to 37.2°C), with variations throughout the day—lower in the morning and higher in the evening. A fever is generally defined as a temperature of 100.4°F (38°C) or higher. Along with an elevated temperature, fever-related symptoms can vary based on the underlying cause and may include:
- Chills and shivering
- Sweating
- Headache
- Loss of appetite
- Muscle aches
- Irritability
- General weakness
- Dehydration
What Does a Fever Indicate?
A fever can be caused by a variety of factors, most commonly due to illnesses or infections. To better understand the cause of your fever, it’s advisable to schedule an online consultation with the best doctors in Bangalore through Apollo. Here are some of the most frequent causes of a fever:
1. Infections
Infections, whether bacterial, fungal, or viral, are among the most common causes of fever. When the body detects foreign invaders, it raises the temperature to create an environment that makes it harder for these pathogens to survive. Some infections that typically cause fever include:
- Bronchitis
- Ear infections
- COVID
- Pneumonia
- Tuberculosis
- Sinus infections
- Flu
- Tonsilitis
- Kidney and urinary tract infections
2. Inflammatory Conditions
Autoimmune disorders and inflammatory conditions can trigger long-term inflammation as part of the body’s immune response. These disorders occur when the immune system mistakenly attacks healthy cells, potentially leading to symptoms like fever. Common autoimmune conditions include:
- Celiac disease
- Lupus
- Multiple Sclerosis (MS)
- Rheumatoid arthritis
- Type 1 diabetes
3. Immunisations
Vaccination helps the body develop immunity against specific illnesses by triggering an immune response. After receiving a vaccine, the body produces antibodies to protect against infections. A mild fever may occur for a day or two post-vaccination, particularly in infants and young children. This is common with vaccines for conditions like mumps, measles, and polio. The fever indicates that the vaccine is working effectively, stimulating the immune system to build protection.
4. Certain Medications
Some medications can cause a fever, though the exact reason is often unclear. Drug sensitivities or their effects on the body’s temperature regulation could be contributing factors. Medications commonly associated with fever include antihistamines, antibiotics, blood pressure medications, and anti-seizure drugs. If you suspect that a medication is causing your fever, consult your healthcare provider for guidance.
5. Heat-Related Illnesses
Heat-related illnesses, grouped under the term hyperthermia, occur when the body struggles to cool itself effectively. This can lead to a dangerously high temperature. The most severe form is heat stroke, characterised by a body temperature of 106°F or higher, which requires immediate medical attention to prevent serious complications.
When Should You Consult a Doctor?
For adults, fevers below 103°F (39.4°C) are generally not a cause for alarm. However, if your temperature exceeds this threshold, it’s advisable to contact your healthcare provider for further evaluation and treatment. You can also seek advice from leading general physicians in Bangalore online through Apollo for quick consultation.
For children, it’s important to consult a healthcare provider if:
- The temperature exceeds 104°F (40°C).
- The fever persists for more than five days.
- Fever-reducing medications like acetaminophen or ibuprofen fail to lower the fever.
- The child’s behavior seems abnormal or concerning.
- They exhibit difficulties with breathing or urination.
A fever is a natural response of the body, often signaling an underlying condition such as an infection, inflammation, or reaction to medication or immunization. While most fevers resolve without complications, some cases require prompt medical attention, particularly if symptoms persist or worsen. Understanding the cause of your fever is essential to address it effectively.
