Some babies often have fever, runny nose, cough, so that parents are very worried, in fact, the baby often suffers from these diseases, in addition to the influence of the external environment, more related to the baby's own immunity, parents should know the baby's immunity, in order to do the necessary health precautions for the baby in the first time.
Babies up to 3 years old
Why is immunity low
Immunity is the body's own ability to defend and fight against various pathogenic bacteria, commonly known as resistance. Your baby's immune system is like a corps that fights germs, once the germs invade, they will fight back and fight back, so that the baby can grow and develop healthily.
However, in babies within 3 years of age, the organs and tissues of various systems of the body have not yet matured, especially the immune function is low, and the ability to resist foreign pathogenic microorganisms is relatively weak. Therefore, they are more susceptible than adults to various germs and various infections.

Baby immunocompromised
of three types
*Congenital immunity reduction
Also known in medicine as immunodeficiency, it is that one or more components of the immune system lose their original function due to genetic mutations and other factors, and immunocompromise occurs, and the condition is more serious. This type of disease is less common in immunocompromised babies, and generally gets sicker, lasts longer, or even lives.
*Acquired secondary immunocompromise
Immunosuppression due to acquired factors, such as infections, environmental pollution, drugs, malnutrition and other diseases, can cause immunodeficiency. When such diseases are removed from the cause of immunosuppression, immune function can often be restored.
*Physiological immunity decline
In fact, it is a gradual process of human growth and is not pathological. In general, children are more susceptible to disease than adults within the age of 7 years, because children's immune function is still mature. Physiological immunosupplexed manifestations are generally less severe than the above two types of immunocompromisedness, most often manifested as respiratory or gastrointestinal infections.
Your baby's immunity is low
of six manifestations
Easy to catch a cold, often sneezing in the morning and evening, runny nose, easy to sweat after movement or night sweats at night, pale face, weak pulses.
Frequent poor appetite, picky eating, anorexia, bad breath, weight and height are not up to standard, sleep restlessness, often have diarrhea or colds, thick tongue, weak pulse, easy fatigue, do not like to walk, like parents hug.
Your baby develops a serious infection after normal vaccination.
Each time the baby gets a more serious disease, the duration is also longer, the disease is pneumonia, kidney disease, urinary tract infection, sepsis, malignant tumors, etc., can have a family genetic history.
Your baby has a cold or tonsillitis more than 6 times a year, or pneumonia 3 or more times a year.
After the baby gets sick, the effective treatment effect is not good, and the disease does not heal for a long time.
Expert tips
When parents suspect that their baby is immunocompromised, it is necessary to find out which of the three immunodeficiency is. This requires a visit to the hospital for diagnosis, and the diagnosis of immunosupplement requires more systematic laboratory tests such as the determination of humoral immunity and cellular immunity to identify the type of immunosuppression, which is very important for the treatment of the disease.
