Allergy is a reaction of the immune system to an allergen. Its task is to protect against foreign contact that could harm our body. Why antibodies are formed in the body that bind viruses and microbes that have penetrated the body, as well as cancer cells.
Neutralized harmful agents are excreted from the body. An immune-protected body can resist infection for a long time. This ability to resist the disease is called immunity.
But if the immune system does not function properly, it can see a threat in components that pose no danger to the body at all. Having considered them pathogens, the body begins to actively form antibodies to them, as a result, the person feels that the body is struggling with the disease, although there are no real sources of the disease.
