What should I know about Allergies?

Allergies are an exaggerated immune response or reaction to substances that are generally not harmful. Normally the immune system responds to foreign micro organisms or particles (like pollen or dust) by producing specific antibodies. These antibodies binds with the molecules or antigens in the foreign particle in order to protect the body from infection. Sometimes, this reaction is triggered by harmless everyday substances (also called as allergen ) resulting in allergy.

Allergens enter the body through four main routes: the airways, the skin, the gastrointestinal tract, and the circulatory system. People with allergies are not equally sensitive to all allergens. Some may have severe allergic rhinitis but no food allergies, for instance, or be extremely sensitive to nuts but not to any other food. Allergies may get worse over time. For example, childhood ragweed allergy may progress to year-round dust and pollen allergy. On the other hand, a person may lose allergic sensitivity.

What causes Allergy?

The substances that cause allergic disease in sensitized people are known as allergens. Allergens enter our body in a variety of ways such as

• inhalation through the nose and the lungs
• ingested by mouth (things that we eat and drink)
• injected things such as stinging insects, injectable drugs and
• things that are absorbed through the skin including poison ivy, oak and cosmetics

What are the likely symptoms of Allergy?

Some common symptoms may include running nose, congestion, or coughing that occurs pretty much constantly and last for 10 days. Most allergic symptoms have a pattern. That is, pollen allergies appear at the same time every year. Pet allergies happen when you are around a certain animal, or, in many cases, just when you enter a building where the animal lives. Dust allergies crop up when you clean house, shake out rugs or enter a very dusty building. Wheezing or frequent coughing could indicate a serious allergy or asthma.

How does one prevent Allergy?

Avoiding allergens is the best means of limiting allergic reactions. For food allergies, there is no effective treatment except avoidance. By determining the allergens that are causing reactions, most people can learn to avoid allergic reactions from food, drugs, and contact allergens such as poison ivy or latex. Airborne allergens are more difficult to avoid, although keeping dust and animal dander from collecting in the house may limit exposure. Cromolyn sodium can prevent mast cell degranulation, thereby limiting the allergic response.
