Information on Allergies

Allergy is a reactions of the immune system to substances. Symptoms of allergy can be triggered to a exposure of the skin, lungs and stomach to particles of dust or pollen (or chemicals).

Some allergic symptoms are Asthma (wheezing), Bronchitis (coughing), Cyanosis ( blue discoloration), Fever, Hives, nausea, and Vomiting.


Allergies in infants

Nasal allergies manifest like the common cold or sinusitis, food allergies produce nausea, vomiting and skin irritation manifests as hives.

 Reaction: The immune system protects  invading agents like bacteria & viruses. In people with allergies the immune system  generates large amounts of a antibody specific to the particular allergen to which he is allergic. This antibody attaches itself to particular cells in the body. The next time a contact with the allergen is made, then allergen attaches to the antibody like a key fitting into a lock. This lock-up causes the release of inflammatory chemicals. These substances, including histamine, move into various parts of the body, such as the respiratory system, to cause allergy symptoms like runny nose, itchy eyes, and sneezing, among others.

Exposure to allergens when the body's defenses are weakened (such as after a viral infection, during puberty, or during pregnancy) may contribute to the development of allergies. People with year-round allergies are more likely to have developed them as adults. Women are more likely to have year-round allergies. Allergy symptoms can lessen as you get older, but they rarely completely disappear.

Allergens: In some people, pollen, pet hair, chemicals, dust,medicines, insect, latex, or foods can cause allergic reactions. Some individuals may be allergic to some situations like reaction to, stress, physical problems, or people in general.

Food Allergies 

When people have an unpleasant reaction to something they ate, they often think that they have an allergy to the food. One out of three people say that some member of their family has an allergy to food that has necessitated a change in their diet. Actually, however, only about 1% of adults and 3% of children have clinically proven allergic reactions to food.

Food intolerance is also an abnormal response to food, and its symptoms can resemble those of food allergy. Food intolerance, however, is far more prevalent,  manifests itself in a variety of diseases, and is triggered by several different mechanisms that are distinct from the immunological reaction responsible for food allergy.
