There are a number
of medical conditions put people at risk for chronic sinusitis.
They include the following:
Asthma or Allergies
People with asthma or allergies or both are at higher risk for
non-infectious inflammation in the sinuses. The risk for sinusitis
is higher in patients with severe asthma. People with a combination
of polyps in the nose, asthma, and sensitivity to aspirin (called
Samter's or ASA triad) are specifically at very high risk for
chronic or recurrent acute sinusitis.
AIDS and other
disorders of the immune system
AIDS and other disorders of the immune system predispose the
patient to sinusitis, with fungal infections being a particular
Pregnancy is sometimes associated with congestion and symptoms
of sinusitis, although the condition is temporary.
Hypothyroidism is associated with congestion that clears up
when the condition is treated.
Cystic fibrosis is a genetic disorder in which the mucus is
very thick and builds up.
Kartagener's syndrome, a very rare genetic disorder in which
the major organs in the body are reversed, and the body's cilia
(hair-like projections on many body tissues that help to move
mucus and other fluids) are motionless.
Wegener's granulomatosis, a serious but very rare illness that
causes long-term swelling and tumor-like masses in air passages.
Dental Problems. Anaerobic bacteria are associated with infections
from dental problems or procedures, which precipitate about
10% of cases of sinusitis.
antibiotics or steroids are also at a higher risk.
