The Environmental Protection Agency (EPA) states that a dust mite allergy can cause asthma in children who have previously not suffered from asthma. Dust mites are microscopic insect-like creatures that are invisible to naked eye and can cause serious health complications, such as blocked airways, according to MedlinePlus. Blocked airways typically need to be assessed by a medical doctor.
Cause
An allergic reaction to dust mites causes the body to produce histamine, a hormone responsible for allergy symptoms. In some people, a dust mite allergy causes the airways to constrict and become inflamed, leading to difficulty breathing. Even if someone has no prior history of asthma, a dust mite allergy can cause restriction in the airways, according to the Mayo Clinic.
Symptoms
Blocked airways from a dust allergy typically will be accompanied with other allergy symptoms, according to Mayo Clinic. Common dust mite allergy symptoms include coughing, chest tightness, chest pain, wheezing, sneezing, eye irritation, nasal congestion and facial pressure and pain, according to MedlinePlus. In some cases, a severe allergic reaction to dust mites can cause the person to become dizzy or faint. This is a serious sign that the allergic reaction is more serious. If this happens, call 911 for immediate medical attention.
Risk Factors
Certain people are at higher risk of developing blocked airways from a dust allergy, according to the Mayo Clinic. Those with a family history of allergies or asthma are at a higher risk. Consistent exposure to dust mites can increase one's chances of developing serious complications from dust mites. Young children and adolescents are more likely to develop a dust mite allergy.
Treatment
Over-the-counter antihistamines are used to prevent an allergic reaction to dust mites. Antihistamines restrict the body from producing histamine, resulting in reduced allergy symptoms. A doctor may recommend participating in immunotherapy, or allergy shots, if breathing difficulty is a chronic problem. Immunotherapy slowly desensitizes the immune system to dust mite proteins and can have significant results.
Prevention and Maintenance
Preventing exposure to dust mites is the best way to prevent blocked airways from a dust mite allergy, according to MedlinePlus. Remove all carpet from the home, use a HEPA air filter system and purchase dust mite covers for all bedding and pillows. Wash bed sheets once a week in hot, soapy water to reduce the amount of dust mite infestation. Keep a clean house, free of excessive dust. Use a face mask while dusting and cleaning.
