Trigger Factors for Asthma

Asthma is one of the most common chronic diseases in the United States as it affects approximately 15 million people.

Typically, asthma attacks are triggered by a variety of common substances. Inflammation of the airways causes an asthma attack, which leads to shortness of breath, wheezing, coughing and chest tightness. During an asthma attack the airways tighten and the airway lining swells, which reduces the amount of air that can pass into the lungs.

Emergency Asthma Symptoms

It is common for individuals with asthma to have a family history of allergies. Asthma attacks can last a few minutes up to several days. Some people have abnormal breathing patterns and it takes them two times longer to breathe air out. Breathing may even temporarily stop in some people.

Emergency symptoms that require immediate medical attention include:

  • Extreme difficulty with breathing
  • Lips and face turning blue
  • Rapid pulse
  • Extreme anxiety because of shortness of breath
  • Profuse perspiration
  • Level of consciousness may become drowsy or exhibit confusion
  • Chest pain may be present along with tightness in the chest

Substances which cause asthma attacks are referred to as allergens or asthma triggers. Asthma triggers for one individual might be totally different than the triggers for a different person. It is important to be aware of triggers in order to avoid them.
