What to do if the baby's fever goes away and then comes back again

The baby's fever comes and goes over and over again. Babies often have fever symptoms during the infant stage because their own immunity is growing, which can make mothers very heartbroken. In fact, fever is a manifestation of the body being invaded by harmful substances. Fever can also awaken people's instinctive resistance, kill germs and improve their own immunity. But what is the reason why the baby's fever comes and goes over and over again?

This is due to infection by various pathogens, including bacteria, viruses, Mycoplasma pneumoniae, fungi, rickettsia, spirochetes and parasites, which cause acute or chronic systemic or local infectious diseases. Such as common bacterial pneumonia, measles, typhoid fever, meningitis, leptospirosis and malaria. Infectious fever accounts for 50%-60% of the causes of fever. It can be seen that the vast majority of fevers in clinical practice are caused by infectious fever. Among infectious fevers, there are bacterial infections, viral infections, etc., which are all things we should pay attention to when using medications.

Fever that persists or is non-infectious

In addition to fever caused by bacterial or viral infection, there are many other factors that can also cause fever. That is to say, fever can occur even without "inflammation", which is medically called non-infectious fever.

1. Central fever

Central fever caused by dysfunction of the solid temperature regulation center, such as heat stroke, severe sleeping pill poisoning, cerebral hemorrhage, etc. The characteristics of fever are high fever without sweating.

2. Absorption of heat

Absorption heat caused by the absorption of sterile necrotic substances is seen in tissue necrosis and cell destruction caused by large-area burns, tissue damage after major surgery, visceral infarction (such as myocardial infarction, pulmonary infarction), leukemia, etc., and fever caused by absorption. 3. Allergic fever

Common causes of fever include rheumatic fever, drug fever, lupus erythematosus, and transfusion reactions.

4. Fever caused by endocrine and metabolic disorders

Common causes include: increased heat production during hyperthyroidism and reduced heat dissipation in severely dehydrated patients, which can all cause fever.

5. Fever caused by neurological disorders

Autonomic nervous system dysfunction affects the normal regulation of body temperature and can also cause fever. The fever caused by autonomic dysfunction is mostly low-grade fever, and is often accompanied by symptoms such as palpitations, dizziness, insomnia, and poor appetite.

6. Fever caused by heart failure or certain skin diseases

In chronic heart failure, the urine volume and skin heat dissipation are reduced, and the limb edema caused by heart failure acts as an insulator, which can increase the body temperature and cause fever. Some skin diseases, such as generalized dermatitis and ichthyosis, also reduce the heat dissipation of the skin and cause fever, but the fever at this time is mostly low-grade.

Fever that persists requires attention

The cause of fever of unknown origin is a worldwide problem, and the cause of nearly 10%%u7684FUO cases remains unknown. Fever itself can be caused by many types of diseases, such as infection, tumors, autoimmune diseases and blood diseases, and cannot be clearly classified. Therefore, if the fever recurs, you must seek medical attention in time to prevent the fever from being caused by influenza or other infections, which will have a serious impact on your body.
