What causes asthma?
The exact cause of asthma isn't known. It's possible that a combination of genetics and environmental exposures interact to cause asthma to develop, most often early in life. Risk factors for developing asthma include:
  • Atopy, an inherited tendency to develop allergies
  • Certain respiratory infections during childhood
  • Contact with airborne allergens
  • Exposure to viral infections
  • Parents who have asthma
  • An asthma attack occurs when asthma symptoms become worse than usual.
