Causes of dust allergies?

Allergies arise the moment the immune system acts against foreign substances, which may well be pet hair, pollen or dust mites. Because of this, the immune system will produce antibodies, which will protect the body from invasive agents. Thus preventing infections from appearing.

When having allergies, the immune system will make the antibodies take care of identifying the allergens as something harmful, even though they do not cause any damage. Once contact is made with an allergen, the immune system will produce inflammatory responses in both the lungs and the nasal passages. Regular or prolonged exposure to allergens causes chronic inflammations that are associated with asthma.

Organic matter is food for dust mites, as in the case of dead skin cells, and instead of consuming water, they absorb any moisture from the environment. Inside the dust are present excrement and also the decomposed bodies of dust mites. Being the proteins found in these wastes, which cause allergies to dust.

The specialist will instruct the patient to take medications to improve the symptoms of this condition, and these may be the following:

Antihistamines: They are responsible for reducing the production of certain chemical substances in the immune system, which are active in allergic reactions. They are medicines that help control some of the symptoms, as in the case of sneezing. These antihistamines are usually prescribed as a nasal spray. However, there are also over-the-counter tablet forms, such as fexofenadine and loratadine.

Corticosteroids: Generally administered as a nasal spray, which reduces inflammation and maintains control of symptoms. Examples of these medications are fluticasone, triamcinoline, among others. The side effects generated by nasal corticosteroids are minor, compared to those that are administered orally.

Decongestants: They can be of great help to decrease inflammation in the nasal passages, and make breathing easier.

And make sure to disinfect the irrigation bottle once it is used, and letting it air dry.

Immunotherapy: There is the possibility of training the immune system to decrease sensitivity to allergens. A measure like this is done through a series of allergy shots, called immunotherapy. The person will be exposed to the dust through two vaccinations per week. Gradually the dose will increase, and the treatment is carried out for six months. Maintenance vaccinations will be required every month for about five years.
