Can sinusitis trigger asthma?

ANSWER

Sinusitis causes inflammation in the mucous membranes that line the sinuses, much like asthma causes inflammation in the lining of the airways. Inflamed sinus membrans secrete more mucus, also similar to asthma. When someone with asthma gets inflamed sinuses, the airways may respond, too.
