Basic facts about allergies.

Do You Have Allergies?
What Is An Allergy?
An allergy is an uncharacteristic response of your immune system. If you have allergies your immune system is reacting to a usually harmless substance in the environment. This substance may be animal dander, mold, pollen, etc. is called an allergen. Allergies are a very widespread problem, affecting at least 2 out of every 10 people.

Why do my eyes run, why do I sneeze and cough? When you are exposed to an allergen, a series of events takes place- Your body starts to produce a specific type of antibody, called IgE, to attach the allergen. Then the antibodies attach to a form of blood cell called a mast cell. Mast cells can be found in the airways, in the GI tract, and other places. The presence of mast cells in the GI tract and airways tract tends to makes these areas more vulnerable to allergen exposure. The allergens attach to the IgE, which is attached to the mast cell. This causes a reaction that allows the mast cells to release a mixture of chemicals including histamine, which causes the majority of your allergy symptoms, including itchiness or runny nose. If the allergen is airborne, the allergic reaction will probably occur in your eyes, nose and lungs. If the allergen is ingested, the allergic reaction often occurs in the stomach, mouth, and intestines. Sometimes very large amounts of chemicals are dumped from the mast cells which causes a reaction throughout the body, such as decreased blood pressure, hives, shock, or loss of consciousness.

What Are Some Common Allergy Symptoms?

Allergy symptoms can be categorized as mild, moderate, or severe (anaphylactic shock). Mild responses will include those symptoms that affect a specific area of the body such as a rash, itchy, watery eyes, and some congestion. Mild reactions do not extend to other parts of your body. Moderate responses will include symptoms that spread to other parts of your body. These may include itchiness or difficulty breathing. A severe response is called anaphylaxis, it is a rare, life-threatening emergency in which the reaction to the allergen is strong and affects your whole body. It may begin with the sudden start of itching or watering of the eyes or face and progress within minutes to more serious symptoms, including abdominal cramps, pain, vomiting, and diarrhea, as well as varying degrees of swellings that can make swallowing and breathing very difficult. Since anaphylaxis causes a quick drop in blood pressure symptoms may include mental confusion or dizziness.

Why Doesn’t Everyone Have Allergies?

The majority of allergies are hereditary, what this means is they are passed on to children by their parents. You may inherit yhis tendency to be allergic, although not to any specific allergen. If one parent is allergic, their your child has a 50% chance of having allergies. This risk shoots to 75% if both parents have problems with allergies.
