The Danger Of Dysphagia


danger of dysphagia


Most of us never consider the physical mechanics involved with eating or drinking. Open, chew, swallow, repeat. It turns out swallowing is a complicated process which demands a perfectly coordinated effort between your brain, nerves and muscle system (If you have superficial siderosis your inner alarm bell should be blasting).

The term Dysphagia covers all swallowing problems but includes two groups. The first type involves a physical or structural problem in your body which impairs movement. The second type, which affects those with neurodegeneration, stem from issues with your neural and motor control center. Malfunctioning nerves responsible for the progressive worsening of dysphagia present a genuine danger to your well being.

Staying Aware

Gary paid a visit to the speech-swallow clinic during our last trip to Little Rock for a Fiberoptic Endoscopic Evaluation of Swallowing (FEES). He occasionally has episodes of coughing or choking with both liquids and solids, a 15-year history of GERD, suffers annual bouts of pneumonia, and one episode of pleurisy with pulmonary infiltrates.

Given his diagnosis of superficial siderosis his neurology team felt it was time to get a baseline test so the speech-language pathology clinic could follow his case in the event symptoms progress. A FEES evaluation only provides information on the oral and pharyngeal phases. To evaluate esophageal problems a different type of test is needed.

Gary’s speech-language pathologist applied lidocaine with a swab to the inside of one nostril. The endoscope tube was lubricated and passed through his nose and nasal cavity.

A monitor displayed the results of several swallow tests. The first was drinking milk. Next, he swallowed applesauce tinted with blue dye. He then chewed and swallowed a cookie and finished up with a cookie and milk combination. Liquid, puree, and solids.

The Mechanics Of Swallowing

There are three distinct (oral, pharyngeal, and esophageal) phases involved with moving your food from your mouth to your stomach.  A specific set of motor and cranial sensory nerves controls each step.

parts of the oropharynx


When you finish chewing the nerves that control the muscles of your tongue and throat will begin to move everything to the upper back part of your throat (oropharynx). Next, as your soft palate elevates to block anything from entering your nose, your tongue and pharyngeal muscles continue to move food into the lower pharynx (throat).


When food reaches the pharynx, your sensory nerves take control of the involuntary phase of swallowing. The swallowing reflex automatically moves everything towards your esophagus. The most critical malfunction during this phase is if your epiglottis doesn’t move to block your larynx off. We’re all familiar with something going down the “wrong pipe” if we accidentally take a breath during a swallow.


Food or liquids move into the esophagus and continue toward the stomach from a combination of muscle contractions and two esophagus sphincter muscles. The upper sphincter closes to stop food from going back up into your mouth. The lower sphincter closes to prevent food from leaving the stomach.

Signs Of Trouble Ahead

Early symptoms may be highly variable and unpredictable as nerve degeneration and motility problems progress. Gary has been diagnosed to be in early stage. His primary concern, for now, seems to be with the mechanics of coordinating the muscles of his tongue and mouth into a swallow.

Symptoms you should be aware of include:

  • Difficulty in moving food to the rear of the throat
  • Feeling that food is stuck
  • Coughing or choking when swallowing
  • Drooling
  • Solids or liquid backing up through the nose

It’s critical your epiglottis protects your lungs from particles of food or liquids; if particles infiltrate the lungs, tissue irritation can lead to severe infection. Lung infections caused by problems with your swallowing reflex are known as aspiration pneumonia.

Swallow Strategies

The speech-language pathologist gave us a list of “Swallow Strategies” to help avoid problems while eating.

  1. Add sauces or gravy to solid foods
  2. Cut food into small bite-sized pieces
  3. Always sit up when eating and drinking
  4. Take small bites or sips, one at a time and swallow
  5. Eat very slowly
  6. Take a sip of liquid after every bite of solids
  7. Place medications into applesauce, yogurt or pudding
  8. Remain sitting upright for 30 minutes after eating


Gary is scheduled to return to the speech-swallow clinic in six months for a follow-up and an updated FEES evaluation test.

    Interesting, I have had increasing problems swallowing over the past year and it is becoming more of a problem. The initial symptoms was clearing my throat when eating, which became more frequent and noisy. Coughing food back into my mouth occurred more frequently and my doctor prescribed Gaviscon Advanced to take after food and before going to bed, to prevent reflux, though I was not aware that I had reflux. The Gavicon helped but the problem swallowing continued, nothing drastic just a nuisance. I had before then been diagnosed as having mild SS. My GP and the local Consultant Neurologist who had referred me from NHS Tayside, Scotland to UCLH NNC London NHS England both said they were surprised and shocked by the unexpected diagnosis of SS, which they knew nothing about. The initial diagnosis recommended at least annual monitoring by MRI, Balance and Hearing Tests but as nothin had been done more than 12 months later, I requested copies of my medical files and the MRI scan form UCLH NNC. I had been aware that a Neurophyisiologist who had tested my facial muscles in 2015 had verbally reported strange signals from my brain when she tested my upper facial nerves but I had not been allowed access to her report. That report was however the main driver for the second referral to UCLH NNC as a brain scan had found no significant difference with previous brain scans. The initial visit to London resulted in two further 1000 mile round trips for what was described as a very special MRI scan and the second for Neurophyisiology and hearing/brain tests. The medical files received from UCLH NNC included the Neurophysiology Test done in Dundee in 2015 and the Neurophysiology Tests done in UCLH NNC in 2016. Though there had been no mention of the Neurophysiology tests results I was interested to note that they were headed ABNORMAL The most significant results to me being the reference to problems with my 7 th cranial nerve. My research indicated that many of the symptoms I have suffered over recent years can be attributed to the problems with my 7 Cranial nerve. Indeed in 2015, I had asked for tests to determine the cause of both my increasing deafness in my left ear and STRANGE SENSATIONS down the left side of my face – hence the initial Neurophysiology Tests done in Dundee. It appeared very significant to me that apart from dry eyes, dry mouth and sinus problems, problems with the 7 Cranial Nerve controls affects eating and SWOLLOWING as that nerve enervates the muscles in the throat AND the 7 Cranial Nerve affects the smallest muscle in the human body which controls hearing AMPLITUDE! I discussed this with my GP who still claimed to have no knowledge of SS, but suggested a referral to a specialist to eliminate throat CANCER! Hence today at o9.00 I will have a Barium Swollow Test. Hopefully I don’t have throat cancer and the problem is due to the previously diagnosed mild SS. And hopefully the AT LEAST ANNUAL monitoring MRI, hearing, balance tests AND FURTHER NEURPHYSIOLOGY Tests will be done some 15 or more months following the initial diagnosis of SS. And perhaps I will the prescribed ferriprox.

      Morris, I certainly second your hope the test doesn’t find cancer! This may be the one instance where a determination this is a superficial siderosis symptom is more preferable. I found during my research that a barium swallow test is one of a few they can do if they suspect esophageal dysphagia. There is some information regarding the facial nerve (VII) and dysphagia at Oxford Medicine
      I hope your test is successful in determining a cause of your problem. I’ll be waiting with great interest for your results. Good Luck!
