The Problem
With 5.2 million diagnosed asthmatics in the UK, Asthma is a common disease which affects both adults and children. Of these 5.2 million asthmatics, 1.1 million are children. Asthma is a condition that has been around for many years and has caused around 1400 deaths per year, of which 90% are preventable. [1]
The numbers of asthma cases have been high due to environmental changes, familial history and lifestyle choices such as smoking during pregnancy to name but a few. It is a chronic condition that affects the airways, causing breathing difficulties. The condition has different levels, long-lasting or recurrent. Mild forms of asthma can affect people, as can very severe cases of asthma. Sufferers of asthma have a lower supply of air to and from the lungs. As this serious condition affects so many people, can it actually be cured?
What is Asthma?
Asthma is a chronic condition that affects the airways of sufferers. The inside walls of the airways are inflamed or swollen. This inflammation makes your airways very sensitive to any form of irritations and causes an allergic reaction to occur. As the airways become inflamed, they become narrower, restricting the flow of air to and from the lungs. This air restriction causes symptoms such as wheezing, chest tightness, coughing and also breathing difficulties. These symptoms are more likely to be experienced at night or in the early morning hours. [2] Many causes and triggers of asthma have been identified. Dust, paint and pet hairs are just a few of the identified examples. [1]
