WHY DOES
PEOPLE
SUFFER
FROM
HALITOSIS
?
Medically, a distinctly unpleasant
odor of the breath (halitosis) may ema-
nate from any patient
with
infections
of
upper
part
of
the respiratory tract,
es-
pecially in bronchiectasis
and
lung ab-
scess.
Halitosis may also occur
with
oral
infections
as
in stomatitis, gingivi-
tis, or extensive
caries.
Some persons
who smoke excessively may have hali-
tosis.
Occasionally,
otherwise
normal
persons may have halitosis with
obvi-
ous
causes.
A fishy odor of
the
breath
is
found in patients with hepatic failure,
an ammoniac or
urinary
odor
is found
in uremia, and a sweet,
fruity
odor
is
typical of diabetic
acidosis.
ln addition,
a bad-smelling breath may be found
in
persons following eating special food
such
as
onion, garlic
or
some drugs
like
antihistamine agents, diuretics
and
sedatives etc.
