Is it hereditary that a 6 and a half year old still has low immunity?

In the eyes of many people, people often cannot distinguish between resistance and immunity. In fact, there is a difference between immunity and resistance. Low immunity refers to low immunity to many bacteria, and resistance is the body's own ability to defend against the outside world. Many people still have low resistance at the age of 66. It is not ruled out that this is due to weak constitution caused by genetics.

In the eyes of ordinary people, they often cannot distinguish the specific meanings of terms such as immunodeficiency and immune deficiency, and thus confuse them.

In fact, low immune function in infants and young children can be divided into three types: congenital immunodeficiency (also known as immunodeficiency), acquired secondary immunodeficiency and physiological immunodeficiency.

Congenital immunodeficiency, also known as immunodeficiency in medicine, is caused by the loss of original function of one or more components of the immune system due to factors such as gene mutation, resulting in immunodeficiency. Xiao Ming is one of these people. When suffering from this type of disease, the condition is generally serious and lasts for a long time. The main manifestations are: recurrent infectious diseases; poor treatment response after infection and long-term disease recovery; serious infection after normal vaccination; similar family history; and easy to develop tumors. Common immunodeficiency diseases include antibody deficiency, T cell deficiency, etc.

Acquired secondary immunodeficiency, as the name suggests, is immunodeficiency caused by other factors. Common causes of acquired secondary immunodeficiency include: malnutrition; use of immunosuppressants, such as hormones, anti-tumor drugs or exposure to radiation; infection with the human immunodeficiency virus (HIV); etc.

Both congenital immunodeficiency and acquired secondary immunodeficiency are pathological and require special treatment.

Physiological immunodeficiency is actually a physiological phenomenon and is not a pathological condition. Similar to human intellectual development, no one can expect children to have the same intelligence as adults. Likewise, we cannot expect young children to have the same immunity as adults.

For children with low immunity, the first thing to do is to find out which condition they are in. This requires an experienced doctor to make a diagnosis with the help of effective examinations. At present, some institutions in China have carried out genetic diagnosis of several common congenital immunodeficiency diseases. If it is congenital immunodeficiency, early diagnosis is very important to improve the prognosis of the child. The treatment of congenital immunodeficiency requires different measures according to the condition, and the treatment time is longer. The key to acquired secondary immunodeficiency is to eliminate the causes of the immunodeficiency. As long as the infected lesions can be effectively cleared, the immune function will gradually recover.
