When talking about causes of asthma is necessary to distinguish between the causes of asthma themselves or etiological factors, and triggers that cause disease if not, can trigger an attack in someone who previously suffered from asthma.
Etiological Factors
- Genetic component: many patients have family members with asthma.
- Exposure to inhalant allergens: are substances that can cause allergies, in particular respiratory symptoms. The most important are: dust mites, pollen from plants (grass, Parietaria, olive, banana ...), pets (hair and skin flakes as the dog, cat or hamster), microscopic fungi (domestic or not, grow damp areas), environmental and labor (snuff, powdered wood, metal ...).
The most important are those related to climate (cold, wet, snow ...), intense physical exercise, polluted environments, especially snuff smoke, respiratory infections, and certain drugs such as aspirin and derivatives.
