What is allergies?
Allergy is not a disease. It is an overstatement of the body’s natural immune defenses. Mild allergies can be annoying, and severe forms can be very serious and/or even deadly. Allergies can vary in the types of symptoms that they cause and the best methods to prevent and treat them. Different type of allergy you get mainly depends on:
- the allergen that provokes your symptoms (e.g. mold or pet)
- the specific areas of the body affected by allergy symptoms (such as the airway, skin or nose)
- whether or not the reaction stays in one place or is triggered throughout the body
There are 3 general rules of allergy, even though each type of allergy behaves differently:
- Allergies always involve the immune system.
- A reaction occurs after exposure to an allergen. The timing may be immediate — soon after contact with an allergen — or delayed — up to two days after contact (such as with poison ivy).
- Prevention is just as important as treatment, if not more.
Here are some examples:
- Asthma is a type of allergy that may be triggered by a large variety of airborne substances, is an overreaction of the immune systems confined to the airways of the lung.
- The symptoms of hay fever or seasonal allergies are mainly caused by pollen in the air, are usually limited to the nose, eyes and the sinuses or the airway.
- An allergic reaction to an insect string can trigger a severe response that affects the whole body. This response is known as anaphylaxis, it is potentially fatal.
Once you have learn the type of allergy you have, you can prevent and treat it on your own.
