Dust mites than they are harmful?

Why are dust mites harmful?

A close, if not invisible, interaction with dust mites is fraught with the emergence of an allergy to a person with a possible overflow into bronchial asthma. The allergen is not contained in mites, or in domestic dust, but in their excrement, more precisely in their component of the digestive enzymes Der p1 and Der f1. At the same time, the chitin of deceased parasites becomes the irritant of the mucous membrane of the respiratory tract.
If physicians distinguish three varieties of allergies, then barn mites cause them all, even individual manifestations of food:




• allergic rhinitis;
• allergic conjunctivitis;
• allergic dermatitis;
• Rhinoconjunctivitis;
• respiratory allergosis - with systemic inhalation of mites and their excrement;
• Acarodermatitis - with dust mite bites;
• deep acariasis - when ticks penetrate into the gastrointestinal tract;

• bronchial asthma and Quincke's edema as a neglected form of allergy.


Symptoms of the disease can be shortness of breath, wheezing in the chest, suffocating cough, watery discharge from the nose, frequent sneezing, itching, red eyes and watery eyes. Especially, these reactions are felt to house dust at night, in the morning after waking up or during the cleaning of the room. Self-diagnosis should not be the reason for buying all kinds of antihistamines, but should encourage a doctor to visit an allergist.

Symptoms of an allergic reaction are usually:

• labored breathing,

• wheezing in the chest,

• suffocating cough,

• watery discharge from the nose (so-called allergic rhinitis)

• frequent sneezing,

• Itching, redness of the eyes and lacrimation (with the risk of allergic conjunctivitis)

• itching and redness of the skin (with a risk of allergic dermatitis)

Especially acute are such reactions to house dust at night, in the morning after waking up or during the cleaning of the room.

The totality of unfavorable reactions of the human body to ticks and their excrement is combined into the concept of tick sensitization, in certain cases not only an unpleasant, but also a dangerous allergy requiring a professional approach to overcome.
