Definition of Adult Asthma
Asthma comes from the ancient Greek word meaning "to pant." An asthma attack suddenly occurs when the bronchial tubes in the lungs gets widespread inflammation. Within the lining of bronchial tubes is a membrane called bronchial mucosa. When patients expose themselves to common asthma triggers like pollen, dust or fumes, the membrane get inflamed and starts to redden and become swollen. The mucous glands within the bronchial lining get over-irritated and start to produce large quantity of mucus. The resulting effect is that air cannot flow in through the lungs as smoothly as before and the patient will begin to gasp for air
Adult asthma symptoms differ from person to person. Coughing and excessive mucus production may show the first sign of an attack. An adult may begin to sweat a lot and rapid breathing and heavy wheezing sound will occur. Sometimes, talking may be an insurmountable task if the breathlessness is severe enough. In extreme cases, the bronchial tubes can be so constricted that wheezing sounds is inaudible.
Many asthma cases are inherited from their own family members. Allergy induced asthma often occurred in families. Asthma is also increasing among the blacks and Hispanics in America. Patients who have asthma appear to have inherited specific genes from their family members and close relatives. Geneticist has noted a gene called ADAM33 which is responsible for making the bronchial tubes oversensitive.
Another gene called PFH11 can also increase the chances of an asthma attack occurring. The gene appears to control blood cells that produce Immunoglobulin E (IgE). These proteins lock onto the surface of mast cells which recognizes allergens. When these mast cells come into contact will the same allergens, the IgE proteins on the mast cells react with them. After which, the mast cell breaks apart and release chemicals causing an inflammation.
One type of asthma that is common among working adults is occupational asthma. Occupational asthma is an asthma that is triggered by a particular material in the workplace. The workplace is home to millions of allergens. Every year, new occupations are added to a growing list when agents that cause asthma are identified. For example, it has been noted that lower temperatures at air-conditioned offices lead to a drier atmosphere. A drier atmosphere is conducive for asthma attacks. Exposure to certain materials like textiles and grains activate the immune system to produce IgE. Stress during working is also known to activate asthma attacks.
