First let’s look at some definitions. Pathophysiology refers to the study of what causes the disruption of ordinary physiological processes so that they become abnormal.
Asthma is a chronic medical condition caused by inflammation of the lungs. In this illness we see bronchospasms due to a heightened reaction to stimuli. This reaction is the pathophysiological response that the lungs undertake when an allergen is present.
The pathophysiological response results in symptoms such as coughing, wheezing and shortness of breath.
Myths About Asthma
There are two things to bear in mind when we talk about asthma:
- Asthma is not “all in the mind” and is not something that a sufferer can choose to get over. It is a serious disease.
- You cannot catch asthma.
Types of Asthma
Intrinsic and extrinsic asthma are the two categories of asthma. An extrinsic asthma sufferer will suffer from allergic reactions and immune responses to allergens. These sufferers are classed as atopic with a problem with IgE responses.
Intrinsic asthmatics on the other hand have an non-allergic response to stress or to infections.
Extrinsic asthma is the much more common type of asthma and is caused by immune response. In this type of asthma, the persons lungs suffer from inflammations and the bronchial tubes are extremely sensitive to the presence of allergens.
Airway inflammation triggers mast cells,eosinophils and macrophages to release in the airway. Together they encourage more mucous to be secreted causing further obstruction of the airway.
Therefore the immune response to allergens results in a two-step process:
- First the lung inflammation causes wheezing and shortness of breath
- Then the bodies mucous production increases which causes coughing in an attempt to get rid of the mucous
In the long-term damage to the epithelium can occur.
Also known as non-allergic asthma, this is triggered by smoke, cold air and even stress. It is important for the person who suffers from this type of asthma to know their own triggers in order to take preventative measures against an asthma attack.
We noted earlier than asthma is not a psychological disease, but stress can make things worse by increasing the body’s response to asthma triggers,
Treatment of asthma depends on the type of asthma that occurs. Mainly, corticosteroid pills and inhalers are used but they come with side effects such as liver and kidney problems.
Increasingly people are looking for a natural cure for asthma. We reviewed an eBook called Asthma Free Forever and concluded it was a safe and natural alternative to facing the side effects associated with steroids.
