What are the common triggers of Asthma?
It is very common in childhood with around 1 in 7 children suffering from it. Many people have chronic asthma throughout their lives with chronic cough, wheeze and shortness of breath.
Acute episodes can be milder, moderate or severe. A mild episode can very quickly change to become severe or life threatening and the risk of life threatening asthma in a casualty who has previously been admitted to hospital with an severe episode is significant.
Acute asthma attacks are commonly caused by two types of trigger factors; they can be allergenic or non-allergenic. Sometimes, there is no identifiable trigger.
Allergenic asthma triggers
- Spores and moulds
- House dust mites
- Animal fur or wool
- Chemicals such as glues and solvent pens
- Food (especially food ‘dust’)
Non allergenic asthma triggers
- Colds and other viral infections
- Temperature (changes in temperature can cause significant attacks)
- Cold air
- Cigarette smoke
