Hay fever

Other names: Allergic rhinitis, Seasonal allergy

DEFINITION

Hay fever, also called allergic Rhinitis, causes cold-like signs and symptoms, such as a runny nose, itchy eyes, congestion, sneezing and sinus pressure. But unlike a cold, Hay fever isn't caused by a virus. Hay fever is caused by an allergic response to outdoor or indoor allergens, such as pollen, dust mites or pet dander.

SYMPTOMS

Hay fever signs and symptoms usually start immediately after you're exposed to a specific allergy-causing substance (allergen) and can include:

Time of year can be a factor

Your Hay fever symptoms may start or worsen at a particular time of year, triggered by tree pollen, grasses or weeds. If you're sensitive to indoor allergens, such as dust mites, cockroaches, mold or pet dander, you may have year-round symptoms.

CAUSES

During sensitization, your immune system mistakenly identifies harmless substances as harmful. When you come in contact with these substances again, your immune system releases chemicals like histamine causing Hay fever symptoms.

RISK FACTORS

Factors increasing the risk of Hay fever include having other allergies or asthma and a family history of allergies or asthma.

COMPLICATIONS

Complications associated with Hay fever include reduced quality of life, poor sleep, worsening asthma, sinusitis, and ear infections.
