What is the reason for frequent high fever

I believe that everyone is familiar with the symptom of high fever. This is a disease that often occurs among all kinds of people, especially those with low immunity. Although high fever is not difficult to treat, as long as certain nursing work is done and medication, injections or infusions are taken as prescribed by the doctor, it can be completely cured, but there are also many patients who often have high fever. So, what are the reasons for frequent high fever?

1. Why do children often have fever?

Children often have fever mainly because the nervous system of infants and young children is not yet fully developed, making them prone to high fever or the body temperature rising quickly after taking medicine to reduce the fever.

Many parents have also observed that their children are prone to having high fevers at night. This is because the water content in infants and young children's bodies is higher than that in adults. Even a slight lack of water will affect heat dissipation and make them prone to fever. When children are sick, they have less strength and sleep for a long time. If you don't eat or drink for a long time at night, your body temperature will naturally rise.

1. Non-disease factors:

The baby's body temperature is easily affected by the external environment: high temperature (heatstroke), wearing too many clothes, insufficient water intake, water loss (sweating, diarrhea), poor ventilation in the room, before and after strenuous exercise, the effects of certain special drugs, and other factors such as preventive injections may also cause fever. If the body temperature becomes unstable, the possibility of illness should be considered.

2. Disease factors:

(1) Fever in infants under 3 months old

Bacterial infection is the most common (such as group B streptococcus); other infections such as respiratory tract, urinary tract, gastrointestinal tract or otitis media can also cause fever. The most serious infectious disease is sepsis. Therefore, when a newborn has a fever, it is important to take the baby to a doctor for examination so that early diagnosis and treatment can be given.

(2) Fever in infants and young children older than 3 months

The most common ones are colds, otitis media, and urinary tract infections. Otitis media is usually caused by bacteria or viruses from a cold infecting the middle ear through the Eustachian tube. Except for severe otitis media where pus can be seen flowing into the ear, most abnormalities cannot be seen from the outside.

2. What should I do if my child often has a fever?

1. Physical cooling is the first choice for intervention when the body temperature is below 38°C

Fever is the most common symptom of infectious diseases in children. The treatment of fever can be roughly divided into "physical treatment" and "drug treatment". Generally speaking, when the child's body temperature is lower than 38°C, there is no need to use drug treatment, but choose the correct physical cooling method. For example, applying a fever-reducing patch, drinking plenty of water, and taking a warm bath can all help lower body temperature.

2. Infants and young children with a body temperature above 38.5°C need drug treatment

If you find that your child's body temperature has exceeded 38.5℃, parents should closely observe the child's condition so as to respond in time. For infants and young children, when their body temperature exceeds 38.5℃, they need to be given medication. For Chinese medicine, you can choose Bupleurum or Antelope Horn. For Western medicine, you can choose Painline, Tylenol or Motrin.

3. If the body temperature is above 39°C, medication should be taken under the guidance of a doctor.

When a child's body temperature exceeds 39°C and is considered a high fever, Western medicine treatment is usually chosen. Currently, ibuprofen and paracetamol are commonly used antipyretics in clinical practice. These two types of drugs are relatively safe. But one thing that must be made clear is that parents should use medication under the guidance of a doctor, especially paying attention to the dosage of the medication.

3. Care for children who often have fever

What parents can do on a daily basis is to provide adequate nutrition according to the child's age and physical development, and add complementary foods in a timely, reasonable and balanced manner.

After ensuring adequate nutrition, we can actively prevent and treat certain nutritional diseases, such as rickets, which is closely related to the occurrence and treatment effect of pneumonia. There are high incidences of diseases in every season, so we should pay attention to the prevention of pneumonia in spring.

A more effective way to prevent disease is to increase your own resistance, take your children out more often or urge them to participate in outdoor activities, and strengthen physical exercise to enhance their ability to adapt to cold climates.
