Many people feel that babies are more likely to get sick than ** in the face of germs, which is due to the fact that babies’ immunity is not as strong as **. Before the baby is 6 years old, his immunity is called “physiological immune deficiency state”, at this time the baby’s immunity is not sound enough, therefore, the baby will be more likely to get sick. So, what is the cause of the baby’s low immunity? 1, suffering from immune deficiency Some babies suffer from immune deficiency, which is due to the baby’s congenital lack of certain types of antibodies or synthetic enzymes, thus causing infectious diseases, if there is such a suspicion, should go to the hospital for immune examination. 2, abuse of antibiotics Some parents rush to give their baby antibiotic drugs as soon as they see him sick, so that the baby develops drug resistance and disrupts the balance of the baby’s body. 3.Unauthorized use of hormones Some parents always want their babies to get better quickly, so they give them hormones, the long use of hormones will seriously affect the baby’s immunity. 4, lack of micronutrients If the baby is not fully nourished for a long time, lack of calcium, iron, zinc, etc., it will cause malnutrition in the baby, thus reducing resistance. 5, unclean environment Due to serious pollution situation, or passive inhalation of second-hand smoke, a large amount of unclean air is inhaled by the baby, which affects the lung function. 6, suffering from congenital diseases Some babies suffer from congenital diseases, such as congenital heart disease, etc., will lead to low immunity. 7, self-medication after the baby is sick, should follow the doctor’s instructions to take drugs, if the treatment course is not enough to stop the drug, the virus is in a hidden state, it is easy to induce disease again. 8, bad habits Some babies habitually eat or drink milk before going to bed, which can also easily trigger a cold, and babies who do not brush their teeth or rinse their mouth before going to bed can easily cause throat inflammation, which can also cause the baby’s immunity to decline. Knowing the causes that induce low immunity in babies, parents should pay attention. First of all, keep your baby away from the environment with bad air, secondly, you must go to the hospital to check and prescribe medicine when you are sick, you cannot take medicine by yourself, and again, your baby should brush his teeth or rinse his mouth before going to bed. If your baby has a strong immune system, the chances of being infected by germs in a crowd will be much less. Therefore, instead of being anxious after your baby gets sick, it is better to advance your baby’s immunity. Improve your baby’s immunity so that your baby can grow up without any worries.
