Allergy is the sixth most common cause of chronic diseases in United States, affecting more than 50 million people.

What Causes The Allergy?

Allergy happens as a body response to certain environmental elements called "Allergen".

Those allergens include pollen's, dust, insect bites, mold, food allergy, medication, and latex.

They stimulate the release of an inflammatory product called "Histamine", which subsequently increase the white blood cell count to fight those pathogens.

The histamine release is responsible for the allergy symptoms. Those allergens might affect the nose and cause allergic rhinitis (Hay fever), irritate the skin and cause allergic dermatitis, or affect the respiratory system and cause bronchial asthma, especially the seasonal one.

Those environmental factors along with the host genetic susceptibility contribute to causing the allergy.

How Does The Allergy Happens?

The body has a defense mechanism to combat the pathogens called "Immune System".

Once the body faces an allergen, the immune system starts to react by producing antibodies called "Immunoglobulin E" from cells called mast cells.

Those immunoglobulins stimulate the release of histamine, which leads to vasodilation, recruitment of white blood cells, and other cells to protect the body against the inflammation and allergen.

This reaction called type I hypersensitivity reaction and is responsible for all the allergy symptoms.

Here are some common health problems & symptoms that are usually associated with allergy:

Allergic Rhinitis
