Definition: An asthma attack occurs when your airways are reacting to asthma triggers. During an attack, more mucus is produced and clogs the airways. Also, the airways swell and their muscles tighten, causing the openings to narrow. Both of these things – narrowed airways and increased mucus production – make breathing more difficult.

Triggers are things than can make your asthma worse and start an asthma attack. Not everyone has the same triggers. Most people have more than one trigger. You need to know what makes your asthma worse.

Here is a list of common triggers:

  • Tobacco smoke
  • Dust mites
  • Animal Dander
  • Cockroaches
  • Vacuum cleaning
  • Indoor mold
  • Pollen and outdoor mold
  • Sprays and odors
  • Exercise, sports, play and work
  • Respiratory infections
  • Cold or windy weather
  • Foods with sulfites
  • Medicines

Examples: The asthma attack started as soon as I petted my friend's cat, with severe wheezing, coughing, and a feeling of chest tightness. It was quickly relieved by my albuterol inhaler.
