The child has a low grade fever and the child has a persistent low grade fever, what is the cause of

Low-grade fever is a common manifestation of many diseases in childhood, and is generally called low-grade fever by axillary temperature, and the causes of low-grade fever are functional and organic, and attention must be paid to distinguishing them. Physiological low-grade fever children's body temperature fluctuates between day and night, slightly higher in the afternoon, but the fluctuation generally does not exceed 1, such as children's activities, crying, excessive clothing, high room temperature and other factors affect low-grade fever is a common symptom of many diseases in children, generally called low-grade fever by axillary temperature, the causes of low-grade fever are functional and organic, and attention must be paid to identification. Physiological low-grade fever children's body temperature fluctuates between day and night, slightly higher in the afternoon, but the fluctuation generally does not exceed 1, such as children's activities, crying, too thick clothing, high room temperature and other factors, so that children catabolism increases, excessive heat production and transient low-grade fever, called physiological transient low-grade fever, also known as physiological low-grade fever.

Constitutional hypothermia is a type of functional hypothermia. In particular, the body temperature in the morning is slightly higher than the body temperature at night, accompanied by hyperhidrosis, fatigue, poor appetite and other manifestations, there are no signs in the whole body, chest X-ray, blood sedimentation rate and other examinations are normal, and antipyretic drugs are ineffective when taking antipyretic drugs when low-grade fever, but low-grade fever can self-resolve. This type of constitution-low fever generally does not affect health.

My child has a persistent low-grade fever, what causes it?

1.It is believed that the infection in the child's body has not been effectively controlled, and he has been experiencing low-grade fever. It is recommended that parents take their children to the hospital for routine blood tests, and according to the results of the examination, symptomatic antibacterial or antiviral** will be given to improve the symptoms of low-grade fever.

Consider eating irregularly, often eating high-protein and high-fat foods, or overeating, which leads to symptoms of indigestion and food accumulation, so that the baby has symptoms such as low-grade fever and decreased appetite. For patients with recurrent respiratory tract infections, it is necessary to strengthen nursing, avoid going to crowded places, keep the home frequently ventilated, and frequently disinfect the room with vinegar fumigation.

2.If your baby has a persistent low-grade fever, the most common cause is that the infection is out of control. In addition to this infectious factor, which can cause persistent low-grade fever, persistent low-grade fever can also occur if non-infectious factors are not removed.

The most common infectious agent is the virus, and if left uncontrolled, a persistent low-grade fever may occur. Your child will need to eat a light diet if he or she has a low-grade fever. Poor digestive function after low-grade fever does not increase the burden on the gastrointestinal tract.

Eat something that is easy to digest and avoid spicy and greasy diets. The diet is based on pasta, and fruits and vegetables can also be eaten. Give your child plenty of water to replace lost fluids.

3.A child's long-term low-grade fever may also be physiological. This low-grade fever is mostly around the degree (axillary temperature).

The child had a good appetite, had no symptoms, and no abnormalities were found through various examinations. In the hot summer, or in a high temperature environment for a long time, such as poor indoor ventilation or children wear clothes that are not conducive to heat dissipation, etc. It is also possible that the body's heat dissipation function is limited, resulting in an increase in body temperature and a low-grade fever.

Observe your child's general condition, and if he is in good condition, can eat and drink normally, and has no obvious chills or drowsiness, he can be observed at home first. A low-grade fever is your child's body's normal immune response. You can first take a physical cooling method, let the child drink more warm water, apply antipyretic patches, or wipe the body with warm water, and give the child a warm bath.

After most physical cooling, their body temperature will gradually drop and return to normal.

I think the main reason for this situation may be because the baby's body has received, the virus infection, or because of the influence of some diseases of the baby, which will cause this to happen, it is recommended to help my mother should take the baby to the hospital for a detailed examination as soon as possible.

It may be because the baby's resistance is too weak, so this situation will occur, and the baby should be taken to the hospital for corresponding examinations in time.

It is very likely that the child has been infected with the virus. At this time, we must find the root of the problem and never neglect the health of the child.

Summary. Persistent low-grade fever in children can be caused by the following reasons: 1. The possibility of tuberculosis infection, because tuberculosis infection is a bacillus, unlike other bacteria that usually have respiratory tract infection, but a kind of medium and high fever, and tuberculosis usually has a low-grade fever in the afternoon; 2. Blood diseases, there are usually no other symptoms in the early stage, there may only be anemia, but parents do not notice, or some children have low-grade fever for a long time.

Therefore, it is also necessary to go to the hospital for a blood test, make a preliminary judgment, and observe the direction of consideration. If there is a significant abnormality in the blood, there may be a hematologic disorder, and other tests such as bone marrow aspiration should be done; 3. Infection with unknown pathogens may also cause fever, including infection with parasites, and may also cause low-grade fever symptoms in children, and the time will be longer.

1.Children who have always had a low-grade fever are mostly related to viral or bacterial infections, and long-term low-grade fever will have obvious adverse effects on physical health, so it is necessary to take the child to a regular hospital for pediatric examination as soon as possible.

2.If the child has a low-grade fever for more than two weeks, it is necessary to carry out targeted bone marrow imaging and immune disease examinations, and through a number of examinations, we can accurately know the cause of long-term low-grade fever, so as to formulate a reasonable and effective method.

3.During the symptomatic treatment, it is necessary to ensure that the child can reasonably increase the amount of water intake every day, and drinking more water can increase the circulation of body fluids, which is beneficial to the discharge of inflammatory substances in the body and the effect of the drug to play a role as soon as possible. The indoor area where you live should also be disinfected regularly to keep the indoor air fresh and circulating.
