Asthma is a disease that causes the inflammation of the airway. It is thought to be caused by a combination of genetic and environmental factors.
Areas with higher pollution, like western Sydney, have increased occurrences of asthma.
My wife and son have asthma, although almost gone in my wife and getting better as my son gets older. It is due to an overreaction of the immune system to irritants that enter the airways. I don’t believe that fully established underlying causes have been pinned down. In some people it is related to exercise, in others it is the presence of pollens or other airborne particles, like smoke. Incidence of asthma can be closely coupled with other conditions like allergies and eczema. Some believe that increased modern incidence of asthma is because we keep our environments too clean, especially around children. A few minor bugs may be good to help develop healthy immune systems in children.
Asthma can be triggered by anything but it is a ‘hypersensitivity’ reaction. The body over-reacts to the presence of pollen or dust etc. and causes inflammation of the wind pipes. Inflamed windpipes don’t let as much air through and so asthma attacks cause people to struggle to get sufficient air into their bodies.
Asthmatic lungs tend to show signs of chronic inflammation and sometimes scarring because of having attacks do often.
