Most common allergies and how to avoid them

Allergies also known as allergic diseases are a number of conditions caused by hypersensibility of the immune system. They occur when the immune system reacts to a substance.

When a patient has an allergic reaction, the immune system makes antibodies that identify a particular allergen as harmful. When the patient comes into contact with the allergen, the immune system’s reaction inflames the skin, airways, digestive system, or sinuses.
