The symptoms of allergies

An allergic reaction may occur in the skin, eyes, lining of the stomach, nose, sinuses, throat and lungs - places where immune system cells are located to fight off invaders that are inhaled, swallowed or come in contact with the skin. Reactions may result in the following:

* rhinitis - nasal stuffiness, sneezing, nasal itching, nasal discharge, itching in ears or roof of mouth.
* allergic conjunctivitis - red, itchy, watery eyes.
* atopic dermatitis - red, itchy, dry skin.
* urticaria - hives or itchy welts.
* contact dermatitis - itchy rash.
* asthma - airway problems such as shortness of breath, coughing, wheezing.

The severity of reaction to these allergens varies from person to person.

Who is affected by allergies?

Allergies can affect anyone, regardless of age, gender, race or socioeconomic status. Generally, allergies are more common in children, however, a first-time occurrence can happen at any age, or recur after many years of remission.

There is a tendency for allergies to occur in families, although the exact genetic factors that cause it are not yet understood. Often, the symptoms of allergies develop gradually over a period of time.

Allergy sufferers may become so accustomed to chronic symptoms such as sneezing, nasal congestion or wheezing, that they do not consider their symptoms to be unusual. Yet, with the help of an allergist, these symptoms can usually be prevented or controlled and quality of life greatly improved.
