Symptoms and Signs of Indoor Allergens

Doctor's Notes on Indoor Allergens

Indoor allergens like almost any other kind of allergen except that they are within the person’s home or workplace. Dust is the main allergen in indoor allergens. The usual symptoms and signs of indoor allergies are the same as for other allergens and include itching, stuffy nose, clear nasal discharge, I discomfort (itchy, watery, swollen), sneezing, scratchy or sore throat, cough, wheezing and occasionally more serious symptoms such as tightness in the chest or some difficulty breathing.

Causes of indoor allergens are exposure to substances like dust, dust mites, dander, molds, cockroaches and household chemicals, for example. These items can trigger the body’s immune response to overreact and secrete chemicals like the histamine that participate in producing the signs and symptoms.
