Allergies: House dust mite allergy

House dust mite allergy is a hypersensitive reaction to proteins in the excrement of dust mites. These proteins can trigger an allergic reaction in the respiratory tract, thus causing the symptoms of asthma and hay fever.

Dust mites are microscopic organisms that thrive in humid and warm houses that have abundant food – animal and human skin and mold spores. The mites prefer to live in beds which has a lot of moisture along with the skin cells shed by the body.

Am I allergic to dust mites?

The excretion of dust mites contains a large amount of proteins. Once these get in touch with the skin or inhaled, the body releases IgE antibodies. On the next exposure, these antibodies start the release of histamine that causes swelling and irritation of the upper respiratory passages. Remember that the tendency for the allergy is usually hereditary.

Since dust mites are around throughout the year, they cause constant allergy or perennial allergy. The wastes by the mites dries out and spread into the air when sitting down a chair, walking over a rug or moving mattresses. These can trigger symptoms of dust mite allergy among allergic individuals.
