First, let’s figure out what “often gets sick” means. Child can hurt 8 times a year or more. It’s not about immunity: kindergartens in winter are unventilated rooms with central heating, where the temperature is like in a solarium. The mucous membranes of the respiratory tract dry out and cease to serve as a barrier to respiratory infections. Together with a child, a family can get sick in a circle, especially if adults also have dry, hot air at home and in offices.
What signs can alert:
- long-term infections that do not respond to treatment. For example, a child has severe sinusitis three times a year, or SARS due to time in time flows into pneumonia, while antibiotics are ineffective;
- severe purulent skin diseases;
- treatment-resistant fungal diseases of the oral cavity, skin;
- allergic reactions.
By the way, another typical situation: a parent complains of frequent illnesses in a child, a constant cough and stuffy nose. During the survey, it turns out that this is a seasonal story, and the tests confirm the allergy. This suggests that the immune system is not weak, but too strong. In this case, it should not be stimulated, on the contrary, it is necessary to “calm” it with means that inhibit the excessive activity of the immune system. This is far from being the first line of therapy, but it is possible if other treatments do not work.
In adults, the situation is generally similar. If there are no severe infectious, autoimmune, oncological diseases, then, most likely, it is not necessary to influence the immune system. In a normal healthy person, it works fine without our intervention.
