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.
