In 1999, Mayo Clinic researchers found
that the cause of most chronic sinus infections was an immune
system response to fungus.
The researchers studied 210 patients
with chronic sinusitis. They discovered fungus in 96% of the
patients. They identified a total of 40 different varieties of
fungi in these patients, with an average of 2.7 kinds per
patient!
"This is a potential breakthrough that offers great hope for
the millions of people who suffer from this problem," says
Dr. Eugene Kern. "We can now begin to treat the cause of the
problem instead of the symptoms"
"Fungus allergy was thought to be involved in less than ten
percent of cases," says Dr. David Sherris. "Our studies
indicate that, in fact, fungus is likely the cause of nearly all
of these problems. And it is not an allergic reaction, but an
immune reaction.
Further study by the Mayo clinic has implicated airborne fungi in both chronic sinusitis and chronic stuffy noses (or rhinosinusitis). To read about the most recent study click here.
The Result of the Problem:
As you breathe, you take in airborne mold particles. Then you
have an allergic or an immune system reaction to these mold
fragments. This reaction causes small pits to form in the
membranes that line the sinuses. These pits trap mucous so that
it cannot drain. The stagnant mucous gets infected which causes
nasal polyps and thickening of the lining that obstructs the
outflow of mucous. The polyps then cause more infection and the
infection causes more polyps. Thus, there is a vicious cycle that
perpetuates itself.
