What is a swallowing disorder?
A swallowing disorder, called dysphagia(dys/pha/juh), is a difficulty or
inability to swallow. There are different phases of the swallow. The
problem can affect any phase of the swallow. What happens in the mouth
is the oral phase. What happens in the throat is the pharyngeal phase.
What happens in the esophagus, called the esophageal phase. A person can
have difficulty in any or all of the phases of the swallow. If the
person can’t eat or drink enough, this will affect their nutrition.
How does normal swallowing occur?
Swallowing is a very complex process that seems to happen so
automatically that we give it little thought. Some 50 pair of muscles
and many nerves work together to coordinate all the movements needed to
transport a bite of food or sip of liquid from the mouth, through the
throat and to the stomach.
What are the different phases of swallowing?
oral phase of swallow is where the food is chewed and prepared, the
liquid is controlled and collected and moved to the back of the mouth.
It is formed into a bolus. The pharyngeal phase of swallow is where the
food/liquid is transported through the throat as the muscles squeeze and
push the food down. A muscle called the upper esophageal sphincter
separates the upper throat (hypopharynx) from the esophagus (the feeding
tube that leads into the stomach). As part of the swallowing response,
the upper esophageal sphincter relaxes and opens to allow the food to
pass from the throat into the esophagus. In the esophageal phase of
swallow a series of wave- like contractions help carry the bolus
downwards towards the stomach. A muscle called the lower esophageal
sphincter opens and the bolus passes into the stomach.
What is aspiration?
Aspiration occurs whenever secretions, food or liquid goes down "the
wrong pipe” and enters the airway or lungs. This often results in
coughing or choking sensation. However, many individuals who aspirate do
not sense the material going the wrong way. Aspirating material into
the lungs may lead to pulmonary problems such as pneumonia.
What is silent aspiration?
Silent aspiration occurs when food or liquid goes down the wrong pipe
into the lungs and the individual does not feel it so does not cough.
What are some signs and symptoms of a swallowing disorder?
- Coughing or choking while eating or drinking
- A wet or gurgly vocal quality during or after eating or drinking
- A feeling like the food is stuck or won’t go down
- Food that may remain in the mouth or in the checks after the swallow
- Losing food from the front of the mouth
- Weight loss or reduced appetite
- Food or liquid coming out of the nose
- Sensation of a "lump” in the throat
Why can a swallowing disorder be a serious medical problem? What causes a swallowing disorder in adults?
If a person cannot eat enough, they may become under-nourished. If they
don’t drink enough, they may become dehydrated. One of the most serious
complications of dysphagia is aspiration pneumonia. Aspiration pneumonia
can be caused by food or liquid entering the lungs and causing an
There are three main causes of swallowing disorders in adults:
Many types of neurological diseases can cause dysphagia. These
include stroke, head injury, multiple sclerosis, Parkinson’s Disease,
dementia and many others.
Surgery or treatment (such as radiation therapy) to the head, mouth
or neck area can result in a change in the anatomy that causes
dysphagia. These are called mechanical dysphagia because the parts of
the anatomy needed for safe swallowing have been altered and don’t move
Sometimes a person becomes afraid to swallow when the swallowing
mechanism is actually still working well. These psychogenic swallowing
problems do not occur nearly as frequently as neurological or mechanical
