The cause of asthma is also recognized as a trigger and one trigger is rhinitis. Allergic rhinitis is unreasonable discharge of mucus glands in the nose, excessive crowding of the veins in the nasal cavity that can cause obstruction of nasal airflow and cause soreness of the sensory nerves in the nose and throat.
These symptoms commonly occur when airborne allergens are breathed in and are usually painless until the immune system responds by producing antibodies. The antibodies adhere to the surface of special cells known as mast cells and put out pro-inflammatory substances including histamines which are a cause of asthma.
These switches in the body cause an blockage to airflow in and out of the lungs and during breathing these obstructions will increase and cause a wheezing and housing of the air in the chest.
Heredity
Heredity is a large reason for asthma in children. The inclination to become allergic is genetic and is kept in line by genes that only act upon the production of an antibody called IgE. Nonetheless, you will only acquire an allergic inherited allergy if open to those certain inherited genes, if you are never exposed you will never get a case of asthma.
Bronchial sensitivity is the fundamental cause of asthma problems. The inflammation of the bronchial walls causes loss of defensive cells from mucosa consequently exposing tender nerve endings to the affected area. This is in all likelihood a direct outcome of genetics.
