Sept. 22, 2008 -- Researchers at a medical conference this week are
suggesting that children with recurrent croup be tested for reflux, which may be a contributing
As any parent who has listened to a child with croup can attest, it is a
scary sound. Croup is characterized by a loud cough that sounds like a seal barking. There can also
be wheezing and difficulty breathing.
Though it is commonly believed that croup is caused by a virus, upper airway
complications have also been considered a factor.
Researchers evaluated 80 children with recurrent croup (more than three
episodes in a year) and found that 26 had narrowing of the airways. Of those
with narrowed airways, 19 had acid reflux that backed up into the throat and
voice box area.
Overall, 56% of the children were suspected to have reflux after evaluation
The researchers presented their findings at the 2008 American Academy of
Otolaryngology -- Head and Neck Surgery annual meeting in Chicago.
They suggest that children with multiple episodes of croup be tested for
reflux. With proper preventive treatment of reflux, future episodes of croup
may be avoided.
