Free topic : Allergy

I want to explain about Allergy. I’m interested in allergy, because in the world, allergic patients are increasing year by year. Allergies are overreactions of immune system. They react very violently when some environmental substances enter your body. The substances is called Allergens. There are a lot of allergens. As you know, chicken egg, milk products and wheat are very famous. Actually, these three allergens amount to more than half number of allergens.

If allergens enter your body, there are a lot of symptoms. For example, difficulty of breathing, rushing in your skin, blood pressure quick falling and they result in anaphylactic shock. Finally, you may die in the worst case.

You must avoid allergens as much as possible. If you can’t avoid the allergens and cause the allergy symptoms. You must receive first aid as soon as possible. And you have to go hospital in hurry.

 By the way, I want to introduce some strange allergies. For example, the water allergy. The water occupy about 60 percent of the body. But water allergy patients react their own sweat, tear and saliva.  In addition, Color of blue, Plastic, Latex, UV are strange allergens too. I think you can’t believe these true or not. Because, these are very important for our life　and very ordinary.

As you can see, there are a lot of allergies in the world.  And I think we must study immune systems and discover new method of treatment for allergy.
