Conditions We Treat

Severe Asthma Clinic

Researchers continue to learn what causes asthma. It is not entirely understood. The following things play a part:

  • Genetics: asthma runs in families.
  • Allergies: some allergies are more common in people with asthma.
  • Respiratory infections: infants and young children who have some respiratory infections are more likely to have long-term lung problems.
  • Environmental factors: irritants, like pollution and allergens, are known to cause asthma.

What causes asthma symptoms to worsen (flare-ups)? 

Triggers are those things that cause asthma symptoms to get worse or asthma flare-ups. Each child has different triggers. A very important part of asthma management is identifying and then trying to avoid triggers. Asthma triggers include:

  • Allergens, such as pollen, dust and pets.
  • Upper respiratory infections, such as colds or the flu.
  • Inhaled irritants, such as secondhand smoke.
  • Certain weather conditions, such as cold air.
  • Exercise or physical activity.
  • Emotion, such as crying, laughing or yelling.
