How common is blocked nose in house dust mite allergy?

House dust mites are tiny organisms found in household dust, particularly in soft furnishings and bedding. In a sensitised person, exposure can trigger inflammation that makes the nasal lining swollen and congested.

Other allergy symptoms may include sneezing, an itchy nose, watery eyes, or clear discharge. Congestion can be more noticeable after time spent indoors, but these symptoms are not exclusive to mite allergy.

Record where and when symptoms occur, including whether they change in the bedroom or around upholstered furniture. This information can help a clinician decide whether allergy assessment would be useful.

Regular cleaning and reducing dust accumulation may be practical steps. Discuss any proposed medicines with a pharmacist or clinician, especially for children, pregnancy, breastfeeding, glaucoma, or high blood pressure.

Make an appointment if nasal blockage is frequent, affects sleep, triggers wheeze, or is not controlled by avoiding obvious irritants. A clinician can look for other causes and explain treatment options.

Seek urgent help if you develop difficulty breathing, swelling of the face or throat, dizziness, or widespread hives soon after exposure. These symptoms can signal a serious allergic reaction.

Ask which aspects of your history support house dust mite allergy, whether testing is appropriate, and how to use nasal medicines properly. Bring a list of treatments already tried and note any asthma symptoms.
