Dust mites, from the arachnid family, can be found in household dust. Individuals with dust mite allergies experience a reaction to a specific dust mite protein. Keeping a house clean may reduce dust mites, but it does not guarantee that the mites will disappear. Symptoms of dust mite allergies are similar to those of hay fever and other environmental allergens. Treatment usually consists of special housekeeping methods and medications, such as antihistamine drugs.
Nasal Problems
Dust mite proteins are usually inhaled through the nose. Once inside the nasal passages, the allergen can irritate the tissues, causing a variety of nasal problems. Sneezing is the body's way of ejecting an unpleasant particle from the airways. This is a common symptom of dust mite allergy. The nose may begin to run, another natural defense, become itchy and even congested.
Eye Irritation
The eyes may become irritated by the dust mite protein, leading to itching, watering and redness. Swelling is possible in the tissues near the eyes. Blue discoloration may appear just below the eyes as a result of sinus pressure caused by congestion.
Throat and Sinus Symptoms
Coughing, hoarseness and sore throat are all possible symptoms of a dust mite allergy. Postnasal dripping from the extra production of mucus may also occur to help protect the sinuses. There may be pain or pressure in the face near the sinus cavities. This is the result of congestion and inflammation.
Other Symptoms
An individual may wake frequently from sleep as a result of the allergy. This can be due to a number of things, including the discomfort of the allergy symptoms. Individuals with asthma may notice an increase in breathing troubles. This can include difficulty taking a breath, tightening in the chest, pain in the chest, wheezing, coughing, whistling when exhaling or waking during sleep due to trouble inhaling, suggests the Mayo Clinic.
