Remind me, what's hay fever?

Hay fever is attributable to exposure of the nose, eyes, and throat to a substance that an individual is allergic to, called an allergen.

Before someone shows symptoms of hay fever, their immune system has already been “sensitized” to a particular allergen, most frequently a grass pollen allergy. Exposure to those allergens means their immune system has made a special form of antibody (called IgE) against them.

During repeated or prolonged exposure to an allergen source equivalent to pollen, an individual's immune system may begin to reply to one other a part of the identical allergen, or to a different allergen throughout the pollen.

Numerous studies show People who've migrated from low- and middle-income countries to high-income countries could also be at greater risk of developing hay fever.

2. Hormonal aspects

Hormonal changes Puberty may additionally help drive the onset of hay fever. It could also be related to sex hormones, equivalent to estrogen and progesterone, Affected Histamine levels, immune regulation, and cellular responses in the liner of the nose and lower airways.

3. Genetic aspects

Our genes pin down Our threat of hay fever, and whether it and other related allergic diseases persist.

For example, children with the skin condition eczema (called atopic dermatitis). Three times the risk of developing hay fever (and asthma) later in life.
