This is the fourth
article in the series on Swallowing Issues. The following information is taken
from the ALS Manual on Swallowingand Adjusting to Swallowing Disorders. Since Kennedy's Disease (SBMA) has
bulbar related issues, there could come a time when swallowing and choking
becomes an issue. I hope you find this information helpful.
On a personal note: Since excessive phlegm and swallowing issues appeared nine months ago, I have noticed a decline in my weight because I have to be careful what I eat and how I eat. Some meals take close to an hour to finish.
Modified Diets and Mealtime
Compensations
The purpose of modifying the consistency of food or liquids is to
compensate for swallowing difficulties you might be experiencing. Altering the
consistency to a more appropriate texture will help reduce energy expenditure
during feeding, chewing, and swallowing. This will allow you to conserve energy
throughout the day and experience less fatigue during mealtimes. Eating foods
that require minimal chewing and moistening foods with sauces and gravies helps
to reduce mealtime fatigue and eating duration.
In the throat, there are two sets of naturally occurring “pockets” that can
catch foods, especially if the muscles involved in swallowing are impaired or
weakened. Oftentimes this causes a sensation of “food sticking” or residue in
the throat. You may feel the need to swallow an additional time in order to
pass the residue and alleviate the sensation of food sticking. Moistening foods
with sauces or gravies can serve as a lubricant and ease the passage of the
food through your throat during swallowing and may reduce the likelihood that
the materials will get stuck in the pockets in your throat.
Taking smaller bites and sips of food and liquid respectively may make it
easier to control the food during the swallow. Additionally, alternating a sip
of liquid every one to two bites of food may help to push the food materials
down to your stomach. If medications become difficult to swallow whole, most
can be crushed and taken with a tablespoon of yogurt/pudding or provided in
liquid form (consult your physician or pharmacist for verification). Four
different levels of modified diets are reviewed in Table 3.
Usually, individuals with safe swallowing do best eating a mechanical soft diet.
This requires less chewing during the oral preparatory and oral phases of swallowing.
Some people, however, may require a more restricted diet if their swallowing is
deemed unsafe.
Coughing, choking, or difficulty swallowing may occur even with the use of mealtime
compensations and dietary modifications. At that time, it may be beneficial to
undergo a Modified Barium Swallow study to determine the safest diet
consistency and safe swallowing recommendations.
Using Thickeners
The
purpose of thickening agents or thickeners is to make regular liquids thicker (more
viscous) and slow the flow rate of the liquid material during swallowing. Recall that
swallowing occurs in less than 2 seconds. During this time over 26 pairs of
muscles and 5 different cranial nerves need to coordinate and move in
a complex pattern to protect the airway and direct the ingested materials towards
the esophagus (food pipe) and away from the windpipe.
Adding a recommended thickening agent to liquids allows the
swallowing system greater time to coordinate and protect the airway because the
thicker liquids move at a slower speed, and in some individuals allows greater
control of liquid material during swallowing (Table 4).
Like the levels of solid food modification, there are also
different levels of thickening for liquids. Thickeners come in powder (starch
based) and gel form and can be added to many of your favorite drinks to make
them safer and more manageable. Your SLP will provide you with information on
how to thicken your fluids to the recommended consistency. Some examples of brands
of thickening agents are, Nestle® Resource Thicken Up, Simply Thick, and
Thick-It.
Coughing or throat clearing during or directly after
drinking liquids is a sign of aspiration.
