Symptoms and causes of allergies

Allergy is a chemical reaction that occurs inside the human body when it comes into contact with any specific material. This normally harmless material interferes with the normal functioning of the body and produces certain compounds within the body. To counteract this, chemicals are released from the body to fight these rogue compounds. This resistance by the body emerges only as side effects known as allergies. However, not everyone is allergic. Some people have weak immunity against specific substances called allergens. Exposure to allergens causes allergy.
