Allergic reaction to dust mites

Causes of this the allergy include;

When your immune system reacts to foreign substances such as dust mite, you end up with an allergy. Your immune system produces an inflammatory response when you are in contact with an allergen.

This response is mostly in your lungs or nasal passage. The chronic inflammation which causes asthma is associated with too much exposure to an allergen.

There are two ways through which dust mites can cause allergies;

  • As they eat, dust mites produce waste. This waste is usually the allergen that causes the allergy for some people.
  • The body parts or bodies of these microscopic organisms are the other cause of allergies. When dust mites die with their bodies being left behind, you will still be in danger of getting dust mite allergies. Produced during their life cycle, the remains following death of dust mites are considered to be second allergen.[1]

Is everyone allergic to dust mites?

Although most people experience the irritation which comes with dust in the surrounding, only some people show a true allergic reaction to dust mites.

The allergic sensitivity varies from one person to another and that explains why not everyone will get an allergy when exposed to dust mites.

According to medical practitioners, these microscopic creatures prefer to feed on the skin of hypersensitive (allergic) individuals because the lipids in their skin are different from those of non-allergic people.

The rashes form when your immune system reacts to certain dust mite protein. Skin rashes that come as a result of dust mites are usually itchy and red, and they form small bumps.

Itching skin

Almost all dust mite allergy symptoms are associated with itchiness. The allergens causing the allergic reaction are responsible for the itching.

The itching can be on the skin, which is in case of skin rashes and hives, or even on your eyes, roof of your mouth or your nose.

Even if you are among the few people who do not portray serious allergic reactions upon exposure to dust mites, you may sometimes feel some itchiness on your body when you are in your house.

The itchiness disappears after a short while and you do not actually see what was causing the itching. In most cases, it is the microscopic dust mites that are crawling on your skin.


Among the many allergens that cause hives are dust mites. Hives are characterized by red blotchy patches which do not stay long on your skin before they disappear.

However, they have a tendency of coming back. Hives appear as raised itchy bumps on your skin.

The bumps that result from skin rashes discussed above may join to form hives. Hives are usually itchy and they can either be acute, that is lasting for days or weeks, or chronic; meaning they go on for months.[2]

Other symptoms associated with dust mites are as listed below and most of them are associated with your nasal passage inflammation;

  • Runny nose
  • Sneezing
  • Nasal congestion
  • Cough
  • Postnasal drip
  • Facial pressure and pain
  • Frequent rubbing of the nose in children
  • Blue colored skin under your eyes (the skin is swollen in most cases)
  • Itchy, watery and red eyes

Where dust mite allergy triggers your asthma, you are likely to portray the following symptoms;

  • Chest tightness and pain
  • Difficulty in breathing
  • Trouble in sleeping following wheezing, coughing and shortness of breath
  • A loud wheezing or whistling sound when you are exhaling

Although most of these symptoms of dust mite allergy may go away on their own, you should see your doctor if your nasal congestion is severe and if the wheezing is making it hard for you to sleep.[3]
