Respiratory Allergy, COPD and Asthma

Respiratory allergies appear when the immune system has a negative reaction with some airborne substance such as dust or we can call the respiratory allergies are airborne. Although these actuality are not really a danger to the body, the antibodies from the immune system find the allergen as a threat. This cause certain cells to produce a chemical substance called histamine, which causes an allergic reaction; while the symptoms of allergy are different from person to person, symptoms can affect the skin, eyes, or airways. Respiratory allergies are mainly rhinitis and asthma. Rhinitis causes irritations of the sensory nerves, which change the nasal passages. Asthma is caused by the infection of the bronchi, which affects the airways within the lungs. But in few cases of asthma, the bronchial walls got bloated thus cause the inflammation of bronchi and thus leads to breathless.
