How to recognize different types of allergies?


Allergies have become a pretty common ailment in today’s world as over 50 million people have some type of allergies. According to medical experts, it is the 6th most common cause of chronic illness among human beings across the world. Usually, allergies occur when the immune system of an individual reacts to some foreign substance in the environment that is harmless to most of the people.

When a person who is allergic to a particular allergen comes into contact with it, an allergic reaction occurs. The process generally starts when the allergens enter the body and trigger an antibody response. The antibodies attach themselves to special cells called mast cells. When the allergen comes in contact with the antibodies, the mast cells respond by releasing certain substance and one of them is called histamine. If the histamine is released due to an allergen, it might result in swelling and inflammation leading to irritation.
