symptoms of dust mite allergies
When you breathe in the waste products of dust mites, your immune system kicks into high gear, producing antibodies against the normally harmless substances. This overzealous immune response causes the symptoms associated with a dust mite allergy, such as sneezing and runny nose. According to the Asthma and Allergy Foundation of America (AAFA), this type of allergy affects about 20 million people in the United States.
1 Dust mite allergies are immune responses to microscopic bugs called dust mites. These bugs live in households and cause reactions like sneezing, itching, congestion, and wheezing.  Allergy medications can help prevent symptoms, but those with more severe allergies may require allergy shots.
Dust mites are tiny insects that are scientifically known as Dermatophagoides. These insects cause allergic reactions in susceptible humans, resulting in hay fever, asthma and other respiratory symptoms. Dust mite allergy is the most common cause of year-round allergy and asthma in the United States. Millions of Americans have dust mite allergy. Dust mites are found in most areas of the world. Symptoms of dust mite allergy in humans develop through breathing and touching waste products of the mites.
