Asthma attacks may include coughing, chest tightness, wheezing, and trouble breathing. An asthma attack can occur when you are exposed to things in the environment, such as house dust mites and tobacco smoke. These are called asthma triggers.

Your personal triggers can be very different from those of another person with asthma. Nonetheless, in every case, it's important to avoid your triggers to keep airway inflammation to a minimum and reduce the symptoms.
