Asthma explained

Asthma is the term used to describe the condition when there is increased sensitivity of the breathing tubes to the environment (allergens such as dust mites, cats, pollutants and infections). This sensitivity can lead to everyday symptoms such as cough and chest tightness to what may be sometimes trivial stimuli such as tobacco smoke and perfumes. However, any tendency to excessive airway narrowing that will lead shortness of breath, wheezing noise from the chest can lead to asthma deterioration. Often nasal problems (termed rhinitis) and asthma will co-exist and it is important to treat both conditions effectively. Cough can be an important manifestation of nose and airway allergy. Exercise related asthma is also a very interesting type of asthma, with a slightly separate therapeutic approach. Understanding the type of asthma determines the approach to treatment.
