Understanding Allergies

Allergies are the abnormal reaction of body’s immune system. Individuals who have allergies will an immune system which responds to a typically nontoxic substance in surroundings. These substances are what we called the allergen. Allergies are very common quandary which affects at least 2 out of 10 Americans. Individuals inherit the propensity to be allergic, even though not to some particular allergen. When one blood relation is allergic, then their child has the 50 percent possibility of having the allergies. The risk would jumps to 75 percent if ever both parents do have the allergies.

The allergy occurs first, when an individual is exposed to the allergen through swallowing it, inhaling it, or acquiring it under the skin. After the individual is out to allergen, a cycle of events make the allergic reaction: our body begins to create a particular form of antibody (IgE), to combine the allergen. Then, the antibodies add to a variety of blood cell known as the mast cell. These could be found in airways, in intestines, and somewhere else. The existence of these mast cells in airways as well as gastrointestinal tract makes the parts more vulnerable to the allergen contact. The allergens combine to IgE that is connected to mast cell. With this, it causes these mast cells to discharge a range of chemicals right into the bloodstream. Histamine, which is considered to be the major chemical, would cause the most of symptoms of allergic reaction.

The common signs and symptoms of allergic reaction to skin, ingested or inhaled allergens consist of:

• Watery, itchy eyes

• Runny, itchy nose

• Sneezing

• Rashes

• Feeling ill

• Inflamed body parts (depending on the area affected)

• Hives

Other exposures could cause a variety of allergic reactions:

• Insect stings. The sting from the bee, an ant or other insect may cause local redness, swelling, and pain.

• Food allergies. These could as well cause vomiting, stomach cramps, or diarrhea.

Anaphylaxis is considered to be the most severe type of allergic reaction. In anaphylaxis, the allergens will cause the entire-body allergic reaction which could include:

• Itching (hives-like rashes) all over the body (not only in exposed area)

• Shortness of breath

• Wheezing

• Tightness and hoarseness of throat

• Tingling in hands, feet, scalp, or lips

Anaphylaxis is a life-threatening and needs instant medical attention. Signs and symptoms could develop rapidly, so go to the emergency room as soon as possible if there is any notion of anaphylaxis because if not treated right away, it would lead to anaphylactic shock and death.
