Anaphylaxis Definition:

Anaphylaxis is a severe allergic reaction that can be life-threatening if not treated right away. It can occur on your body within no time. It generally occurs when you get exposed to something with which you have an allergy including bee stings or peanuts. Due to anaphylaxis, the immune system of a person can release a lot of chemicals that can cause the person anaphylactic shock. Because of this, there can be a sudden drop in blood pressure, blockage in breathing, and airways can become narrow. Vomiting, weak or rapid pulse, nausea and a skin rash are some of the signs and symptoms of anaphylaxis. In order to treat anaphylaxis, a person needs an immediate injection of epinephrine or adrenaline. If adrenaline injection is not available, then the person should be taken to an emergency unit. Sometimes, it can be life-threatening if not treated properly on time.
