- QUESTION: Though I have nursed my allergies for years, and probably spent
- more on medications than vacations, I still am not sure what this miserable
- condition is all about. Could you turn your special talent for explaining
- about disease to this, and tell me about it so that at last I will understand
- it all?

- ANSWER: That's quite an order, but I'll try. The best one sentence
- definition of allergy is that it's an overreaction of the body's immune
- system to something that it probably shouldn't have reacted to in the first
- place.
- The immune system is normally great at learning to identify potential
- dangers, such as bacteria and viruses, and then remembering them and attacking
- them the next time they show up. In a person with allergies, the immune
- system over reacts and starts attacking things like pollen, mold spore, house
- dust, mites, animal dander, or certain substances that are eaten, inhaled or
- touch the skin. These "allergy causers" are called allergens.
- In the case of an inhaled allergen, antibodies react to the allergen's
- presence and attach to the nasal passages and upper respiratory tract and
- start attacking. The antibody destroys the allergen, but also wrecks havoc on
- the surrounding tissue, resulting in sneezes, sniffles, watery eyes, and a
- stuffed-up head. An allergic response in the skin may appear as eczema or
- hives, while one in the intestinal system may show up as diarrhea, cramps, or
- vomiting.
- Allergic responses can vary in intensity from mild sniffles all the way
- to anaphylaxis, a potentially life-threatening situation, intense reaction.
- Anaphylaxis is most often caused by allergies to insect venom, penicillin, or
- certain foods such as fish, peanuts or eggs.
- I've simplified things a bit for you, but the field of immunology is one
- of the most exciting in medicine, and research in this area may soon produce
- answers to a great many important medical questions.
