Exposure to asthma
Asthma can come out at any age. All our lives we are exposed to asthma, because we are still exposed to many foreign substances for the body. The effect of the increasing amount of pollution in the surrounding environment is irritated mucous membrane of the airways, because it first contacts the outside world. Over time, the bronchial mucosa begins to react excessively to the irritating stimuli, we are at risk of being exposed to asthma.
The effect of excessive bronchial reaction may be allergy. Sensitization (allergy) may be caused by pollen of flowering trees, which during the flowering season get into the respiratory tract along with the air, irritating the bronchial mucosa. Sometimes the reaction of the body is so strong that it comes to the contraction of the muscles of the bronchi which we feel as a fit of shortness of breath.
Baker’s asthma is proof that constant contact with certain substances can cause the development of bronchial hyperresponsiveness. Baker constantly inhales small amounts of meal dust which causes some allergic reaction. The mucous membrane of the respiratory tract becomes hypersensitive and after a few years there is allergy to the flour and to symptoms of asthma.
Asthma may also appear in people who have other allergic disorders, so-called hay fever (pollinosis). Over time, the disease progresses and allergic symptoms are transferred from the conjunctiva and the nose to the lower respiratory tract, ie, the bronchi, giving typical asthma attacks. Asthma is not always allergic. Frequently recurrent respiratory tract infections, damaging the chronic bronchial mucosa, may lead to hypersensitivity and, after some time, to bronchial asthma.
