What is Asthma?
Asthma is a common and long term lung condition that requires ongoing management. It affects about five million people in the UK. This information is for adults and children over 12 years old.
The symptoms of Asthma commonly start in childhood but it is possible to develop asthma at any age. Asthma tends to run in families, especially when there's also a history of allergies and/or smoking. This condition can be well controlled with a good Asthma action plan.
What happens in asthma?
Your airways carry air in and out of your lungs. If you have asthma, they are very sensitive. Certain things trigger the muscles around your airways to tighten, making your airways narrower. The airway lining also becomes inflamed causing a build-up of sputum. This makes your airways even narrower. With narrow airways, it’s harder to get air in and out of your lungs.
How does asthma affect the airways?
When a person with asthma comes into contact with something that irritates their sensitive airways even more (an asthma trigger), it causes their body to react in three ways:
the muscles around the walls of the airways tighten so that the airways become narrower
the lining of the airways becomes inflamed and starts to swell
sticky mucus or phlegm sometimes builds up, which can narrow the airways even more.
These reactions cause the airways to become narrower and irritated - making it difficult to breathe and leading to asthma symptoms, such as chest tightness, wheezing, or coughing.
Asthma is a disease that extensively contracts our breathing ways in lungs (bronchus). This happens as a result of some stimulants.
This contraction can recover by medicine or sometimes by itself. There are many reasons of this contraction:
Muscles around bronchus can be stretched
Bronchus can excessively secrete sticky mucus
There can be Oedema on bronchus wall
Veins in bronchus can enlarge and new veins can be formed.
Cells that lay down bronchus can fall.
Cell walls can become thick as a result of connective tissue increase.
Various inflamed cells can come together on bronchus walls.
The most important change in asthmatic’s bronchus is the inflammations on which eosinefil cells are dominate. This allergic inflammation continuously exists even at recovering periods of the illness. Bronchi of asthmatics show excessive sensitivity to both allergic and non-allergic stimulants (cold weather, training, smoke, smell…). We call this as bronchus hyperactivity. That’s why a sharp smell and cigarette smoke cause cough, growling and shortness of breathe on asthmatics. In the light of this information we can say asthma has three main characteristics:
Extensively contraction on bronchus.
Allergic inflammation on bronchus.
Excessive bronchus sensitivity.
