Pollen Allergy

Pollen is one of the most common triggering factor for seasonal allergies. This seasonal allergy if often referred to as “seasonal allergic rhinitis” or hay fever.

In different season, mainly in spring, summer and fall, several plants release tiny pollen grains to fertilize other plants of the same species.

Pollens mainly come from

Grasses: Grasses are the most common cause of seasonal allergy.

Trees: some species of trees, including birch, cedar and oak, highly allergenic pollen.

Weeds: Ragweed is a main cause of weed allergies. Other sources of weed pollen include sagebrush, pigweed, and tumbleweed.

Pollens are wind pollinated. This means that these small tiny pollens are travel by wind.

Skin prick testing (SPT) or Prick skin testing (PST), is a widely used, high quality, low risk allergy test to demonstrate immediate IgE-mediated allergy. The test is cost effective. The test should be performed by a trained person.

Allergen specific IgE testing- Blood testing for allergen-specific IgE is usually performed when the skin prick test is contraindicated. They can also be done in extreme of age i.e., an infant and elderly patients where skin prick test is not appropriate.

Treatment for Pollen Allergy

The most important step is to avoid pollen

Certain over-the-counter and prescription antihistamines.

Nasal corticosteroids spray.

Leukotriene receptor antagonists


Immunotherapy (allergy shots).

Pollen-food syndrome

Pollen food syndrome can occur with Tree nut. Pollen-food allergy syndrome also known as oral allergy syndrome. Pollen-food allergy syndrome may affect many people who have allergic rhinitis/ hay fever. In this condition, certain fresh fruits and vegetables can trigger an allergic reaction that leads to tingling sensation and itching in and around the mouth. In rare cases, it can trigger a severe form of allergy called anaphylaxis.

The main reason for oral allergy syndrome is the cross-reactivity of proteins of certain raw fruits and vegetables with certain pollens. Symptoms of food allergy may reduce if someone cook the food and vegetables properly.

If a person is allergic to Birch pollen then he may react to Hazelnut.
