Zenker's diverticulum usually presents
in an older person with difficulties to swallow.
Generally, it's solids that give the patient
the majority of the difficulties,
and liquids are not so hard,
they often pass without a problem.
One of the things that happens
is that the food will get stuck in the diverticulum,
which is actually a sac.
And because of that, the patients will often complain
not just of food sticking, but of fullness in the neck,
and then they'll actually cough out the food
20 or 30 minutes later, after eating,
and the food will be completely undigested
because it's been sitting in their throat
and hasn't gone down to the stomach,
where it would have been digested.
So that is something that's very typical
of a Zenker's diverticulum.
