Allergic To Dust Mites

How do you become allergic to dust mites?

An allergy is an over reaction of your immune system to a normally harmless substance called an allergen. If you are allergic to dustmite, you are sensitive to a very common inhaled allergen trigger, house dust mites and their faeces.

Other common inhaled allergen triggers include dust, pollen, animal dander from cats and horses, mould and mildew, feather and down, chemical smells. Ingested allergens include a wide variety of foods, peanuts, dairy, wheat, eggs and a plethora of others. Another group of allergy triggers include medications, latex and insect stings.

On your first exposure, the inhaled allergen enters the nasal passages lined with mucous membrane.

Here the allergen is taken up by the antigen presenting cell which presents it to the T cells, recognising the allergen as a foreign body.

These T cells instruct the B cells, type of white blood cell, to release antibodies called IgE (immunoglobulin E) against the allergen.

These IgE antibodies sit on the surface of the mast cells. The mast cells have granules containing chemical mediators like histamine and prostaglandins.

On exposure, the allergen binds to the IgE antibodies present on the mast cells, cross linking them. T cells, B cells and mast cells combine to ignite the body’s immune system response to an allergen.

When you are re-exposed to the same allergen, it attaches itself to antibodies that are stuck outside the mast cells.

This results in the release of histamine, prostaglandins and other mediators into the surrounding tissue, communicating between immune cells.

The histamine binds to receptors on the blood vessels. These histamine mediators cause dialation of the surrounding blood vessels, increase their permeability and causes swelling, redness and inflammation.

The results are nasal stuffiness, runny nose, itchy, watery eyes, sneezing and mucous discharge of allergic rhinitis, wheezing and shortness of breath, unable to stop coughing, hives, headache and fatigue.

Primarily, histamine is responsible for what causes asthma and other allergy related symptoms. They are responsible for skin reactions to allergens such as chemicals found in personal care products, make up and off the shelf skin care products.

Antihistamines work by blocking the action of histamines, neutralises, at its receptors and thus decreasing the body’s reaction to the allergen.
