Question

Which type of pollen cause pollen allergies?

Answer 1

There are three main types of pollen that cause allergies

• Tree pollen
• Grass pollen
• Weed pollen

It happens when the immune system begins to produce chemicals including histamine to fight against the pollen. This is known as an allergic reaction, and the specific type of pollen that causes it is known as an allergen. The allergic reaction leads to numerous irritating symptoms:

• Sneezing
• Stuffy nose
• Watery eyes

Answer 2

Pollen from grass, weeds, and trees are common to cause hay fever (allergic rhinitis).
