The Asthma and Allergy Foundation of America states that over 20 million Americans have a dust mite allergy. Dust mites are small, microscopic insects that live mainly in dust, bedding and pillows. People with a dust mite allergy suffer from the mites waste, shedding and the mites themselves. Dust mites prefer to live in moderately humid conditions, between 70 and 80 percent humidity. Some of the most common symptoms of a dust mite allergy are nasal inflammation, asthmatic reaction and eye irritation. Many times dusting or vacuuming a room or a home can spark dust mite allergy symptoms.
Nasal Inflammation
The most-common dust mite allergy symptom is nasal inflammation. As the body releases high levels of histamine to ward off the dust mite byproducts, it can cause mild to severe nasal inflammation. When the sinus cavity becomes inflamed it swells, over-produces mucus and drains excessively. A person may experience a runny nose, bouts of sneezing and postnasal drip as a result of the nasal inflammation, according to the Mayo Clinic. If the nasal inflammation persists or worsens, an individual should seek medical advice. Nasal inflammation can lead to a sinus infection, which if not treated can lead to more serious complications.
Asthmatic Reaction
The American College of Allergy, Asthma and Immunology says that a dust mite allergy is believed to be a contributing factor in the development of asthma in children. A dust mite allergic reaction may cause the tightening of the chest, difficulty breathing and wheezing. A person may also react with bouts of coughing. If a person experiences these symptoms accompanied with dizziness, lightheadedness or nausea, she should seek medical attention. Minor asthmatic reactions are common but could cause a serious health threat, if not properly treated.
Eye Irritation
The eyes can become irritation from a dust mite allergy. If a person is sleeping on a bed or pillows infested with dust mites, he may experience more sever eye irritation. In young children it is common for them to rub their eyes and have difficulty sleeping. The eyes may feel itchy, dry and suffer a burning sensation. The surrounding areas of the eye can become inflamed and swollen. In severe cases, the swelling can turn black and blue, looking like a black eye. Complications from eye irritation can include an eye-socket infection. An individual with severe pain or disoriented vision should seek medical attention immediately.
