What are the symptoms of house dust mite allergy?

The symptoms happen when the immune system reacts to proteins from mites and their waste in household dust. They may continue through the year because mites live in bedding, mattresses, carpets and upholstered furniture. Symptoms can be worse after sleeping, cleaning, or spending time in a dusty room. Some people also develop wheezing or chest tightness, particularly if they have asthma. An itchy throat and frequent nose rubbing can accompany the nasal symptoms; fever is not a typical feature of an allergy.

Notice when symptoms appear and whether bedding, carpets, or cleaning brings them on. Reduce dust exposure by washing bedding regularly at a hot temperature suitable for the fabric, using mite-resistant covers, and keeping bedrooms well ventilated. A clinician can review your pattern and medicines, and may arrange Allergy Testing when the trigger is uncertain. Treatment may include an antihistamine or a nasal spray; use medicines according to professional advice.

Arrange medical advice if symptoms persist, disturb sleep, or interfere with work or school. Seek urgent help for severe breathing difficulty, rapidly worsening wheeze, swelling of the lips or tongue, faintness, or trouble speaking in full sentences. These signs need prompt assessment rather than home dust-control measures alone.

Could my symptoms be caused by house dust mites or another trigger? Which treatment suits my symptoms, and how should I use it? Do I need testing or an asthma review if I wheeze?
