Signs and symptoms of a dust mite allergy

Dust mites are common tiny bugs that live in household dust. They are also an allergen for some. A dust mite allergy causes inflammation of nasal passages and shares symptoms with hay fever, like runny nose and sneezing. Some may also experience signs of asthma, such as wheezing and difficulty breathing, according to the Mayo Clinic.

“Dust mites, close relatives of ticks and spiders, are too small to see without a microscope,” explains the Mayo Clinics. “Dust mites eat skin cells shed by people, and they thrive in warm, humid environments. In most homes, such items as bedding, upholstered furniture and carpeting provide an ideal environment for dust mites.”

Though reducing the number of mites in your home can help with the allergy, sometimes medications or other treatments are necessary to alleviate symptoms and manage asthma.

Symptoms can range from mild to severe, with mild cases experiencing only an occasional runny nose, watery eyes and sneezing. In more severe cases, the condition may be chronic, with persistent cough, sneezing, congestion, facial pressure or severe asthma attack.

“If symptoms persist for longer than one week, you might have an allergy. If your signs and symptoms are severe — such as severe nasal congestion, wheezing or difficulty sleeping — call your doctor. Seek emergency care if wheezing or shortness of breath rapidly worsens or if you are short of breath with minimal activity.”
