Risk Factors for Developing Asthma

Genetic characteristics

Occupational exposures

Environmental exposures

risk factors for developing asthma genetic characteristics
Risk Factors for Developing Asthma: Genetic Characteristics

Atopy

The body’s predisposition to develop an antibody called immunoglobulin E (IgE) in response to exposure to environmental allergens

Can be measured in the blood

Includes allergic rhinitis, asthma, hay fever, and eczema
