Dealing with Asthma and Allergies

By Adem Lewis / in , , , , , , , , , , /

Your immune system protects you from
potentially harmful substances in the things you eat, breathe, or touch. But the
immune system of someone with allergies sees certain substances which are
harmless to most people as things to react to and this triggers an allergic
response. People who are predisposed to allergies produce excess IGE antibodies.
When an allergic person comes in contact with an allergen it can combine with a
specific IGE antibody which causes histamines, leukotrienes, and other
chemicals to be released from cells in the body tissues. This is what causes
allergy reactions like sneezing, itching, swelling of tissues in the nose and
airways, coughing, wheezing, and other symptoms. Each type of IGE reacts with
only one type of allergen. That’s why some people are only allergic to cat
dander while others are allergic to many things. During an asthma attack, your airways or
bronchial tubes constrict or tighten and may become inflamed in response to
certain triggers. This means the lining of the tubes that bring air to the lungs
is swollen, which makes it more difficult for air to move freely in and out. Glands
in the lining of your airways may produce extra mucus which accumulates
in these already narrowed tubes and contribute to the problem.
