    Sneaky Allergy Asthma Triggers

    What Severe Asthma Looks Like

    Video Transcript

    [MUSIC PLAYING] SPEAKER: An asthma attack happens when you are exposed to an allergen or some other trigger, like a virus, cold air, exercise, stress, or environmental pollutants. Your airway's become inflamed and swollen, and the muscles in your chest tighten.

    Your breathing tubes become narrow, and make extra mucus, making it hard to get enough air into your lungs. Your airways start to overreact, causing spasms that lead to wheezing and coughing.

    A severe asthma attack can cause shortness of breath, and a tight feeling in your chest. Your skin may pull in slightly between your ribs. You may have hunched shoulders, and strained abdominal and neck muscles. Your face and lips may have a blue tint. And you may feel confused, agitated, or unable to concentrate.

    A severe asthma attack can be life threatening. If your symptoms aren't improving with home treatment, see a doctor right away.
