What are the causes of milk allergy in babies?

When the baby is young and cannot eat complementary foods, milk powder is one of the baby's staple foods. If the baby is allergic to milk powder, this is the most worrying and fearful thing for all mothers. There are many reasons for baby's milk allergy. When facing the baby's milk allergy, don't panic. It is the best way to go to the hospital in time to find out the cause of the baby's allergy. Let’s take a look at the causes of baby’s milk allergy.

Causes of milk allergy: 1. Changes in living environment: In industrialized cities, air pollution is becoming increasingly serious. Automobile exhaust is also the culprit of pollution. Chemical substances such as nitrogen compounds and sulfur dioxide and suspended particles in the air are pollutants that fill the atmosphere. Polluted air constantly irritates the baby's respiratory organs. If things go on like this for a long time, it will easily cause the baby's respiratory resistance to decrease.

2. Family genetic factors: Studies show that if both parents have a history of allergies, the baby’s chance of developing allergies is 60-80%. Even if only one parent has a history of allergies, the baby’s chance of developing allergies is 20-40%. The results of a large number of surveys and analyses show that babies without a family history of allergies have a relatively low risk of allergies (we call these babies low-risk children), but the chance of allergies can be as high as about 15%.

3. Immature immune system: The baby's immune system is immature: The human immune system has two directions, one is immune protection, and the other is prone to allergies.

4. Imperfect intestinal barrier function: The intestine is immature during infancy, and the intestinal mucosa is the natural barrier for infants to resist invasion by harmful external substances. Mature intestinal mucosal epithelial cells are arranged tightly, like a "wall" without any gaps, but the intestinal mucosal epithelial cells of young infants are not arranged tightly and there are gaps. Some food particles such as milk protein molecules can easily pass through this barrier and enter the blood from the intestinal cavity, causing allergies.

Recommendation: If your baby is found to be allergic to milk powder, you can choose anti-allergic milk powder. As the name suggests, it is a kind of milk powder that can effectively prevent or avoid milk protein allergies by adding a certain specific anti-allergic formula.

Don't worry if your baby is allergic to milk. The first thing we need to do is to determine what type of allergy your baby has. For example, some babies are simply not adapted to it. Of course, some babies are not adapted to the lactose in the milk powder. In the face of these problems, we mothers must first choose milk powder suitable for our babies, and it is best to buy it under the doctor's advice.
