Swallowing difficulties
Multiple sclerosis (MS) can cause swallowing
difficulties – also known as ‘dysphagia’. Between
30% and 40% of people with MS experience
difficulties with swallowing at some time, though
for some people changes are so small that they
are hardly aware of them.
Picking up these small changes to swallowing can
help avoid possible complications. This booklet
points out some of the signs to look for and ways
to manage them. Health professionals including
speech pathologists can help diagnose problems
and find the best treatments, but there are also
techniques that you, your family or carers can learn
to help with swallowing.
Just like any other symptom of MS, swallowing
difficulties may come and go. For example,
temporary changes in swallowing can happen
during a relapse and improve, or disappear
completely, over time.
For others, swallowing can become more difficult
in the long term. But however long symptoms last,
there are practical things that can help you manage
the changes effectively and make swallowing as
comfortable and easy as possible.

difficulties and help avoid possible complications4. You might be aware of problems yourself, or
it may be friends and family who notice the first changes. It could be your doctor or MS health
professional. Some of the signs will be obvious, others may be more subtle – and you may have
