WHAT CAUSES ASTHMA: PREDISPOSING FACTORS

IT IS NOT known with certainty what exactly causes the development of asthma, but it appears to be a complex interaction of many factors.
Predisposing factors
A hereditary predisposition makes a child inherently susceptible to the disease. This includes the propensity to produce abnormal amounts of harmful IgE (Immunoglobulin E) antibody leading to an allergic reaction which causes inflammation of the bronchial tissues in response to environmental allergens. This phenomenon is also called atopy.
Children from families having a history of asthma are more likely to suffer from this problem. The greater the degree of inheritance, the greater the likelihood of the offsprings becoming sensitive. Further, when both the parents are affected, the disease in the children appears earlier, and often before puberty. However, heredity alone does not produce asthma. It only makes the child more suscetible.
Children inherit an allergic predisposition rather than a specific allergic disease; children of a parent suffering from hay fever may develop asthma or eczema, and not necessarily hay fever.
