ASTHMA TRIGGERS AND SYMPTOMS
What are the causes of asthma?
No one is sure what causes asthma, and, so far, there is no cure for it. However, we know that asthma is a chronic inflammatory lung disorder that can be controlled. With asthma, substances or conditions called triggers cause air passages in the lungs to become inflamed and swollen. Things that trigger an asthma attack in one person may not be a problem for another.
SINGULAIR has been proven effective in helping to prevent asthma symptoms. However, the effect of SINGULAIR on asthma symptoms caused by individual triggers has not been studied.
ASTHMA SYMPTOMS
The most common symptoms of asthma:
- Chest tightness
- Coughing
- Shortness of breath
- Wheezing
Sometimes coughing is the only symptom. Asthma symptoms often occur at night or during exercise, but they can occur at any time.
What happens during an asthma attack?
Exposure to a trigger causes the body to produce increased amounts of a number of substances that occur naturally in everyone’s lungs. Increased amounts of these substances contribute to the swelling and the narrowing of the air passages. One type of these substances is called leukotrienes (loo-ko-TRY-eens). Leukotrienes have been associated with symptoms of asthma.
