Dysphagia: Understanding Swallowing Difficulties and Importance of Medical Care

difficulty swallowingMost of us swallow hundreds of times each day without much thought, relying on numerous mechanisms to move foods and liquids from our mouths to our digestive system. We often consider swallowing an automatic function. When the processes involved work in harmony, swallowing is effortless.  

But swallowing is not always easy. Statistically, one in seventeen people will develop swallowing difficulties at some point in their life, a condition known as dysphagia. According to the Agency for Health Care Policy and Research, more than 60,000 people in our country die from complications of swallowing dysfunction every year.  

If you are experiencing swallowing difficulties, it's important to recognize the symptoms of dysphagia and consult your health care provider for a consultation or evaluation.  

Mechanisms Involved in Swallowing

Effortless swallowing requires the coordination of a significant number of nerves and muscles groups. The process of swallowing occurs in phases. First, food is chewed to a size and consistency that is easy to swallow. Then, as the tongue rises, food is squeezed along the roof of the mouth into the upper pharynx as the pharyngeal muscle relaxes to let food in. The muscles then contract sequentially moving food further downward. In the final stage, the tight ring of muscles at the bottom of the esophagus relax so food is allowed to enter the stomach.

Dysphagia may be far more common than you realize. Swallowing difficulties can occur when any of these processes are disrupted by nerve damage, muscle weakness, or obstruction. Most often, dysphagia is caused by other health conditions. Just a few of the many conditions known to increase the risk of developing this disorder, including:

  • A weakening of the musculature with age
  • Neurodegenerative disorders (Parkinson's disease, multiple sclerosis)
  • Conditions or medications that decrease saliva production (Sjogren's syndrome)
  • Brain injuries or damage to the spinal cord
  • Gastroesophageal reflux disease (GERD)
  • Cancer of the mouth or esophagus (or other obstruction)
  • Conditions that cause muscle weakness (myasthenia gravis, muscular dystrophies)
  • Pharyngeal pouches (large sacks developing in the upper esophagus)
  • Radiation treatment

Some people living with dysphagia have difficulty swallowing solids, while others struggle with liquids. Depending on the nature of the disorder, many people have difficulty swallowing regardless of consistency or texture.  

Recognizing the Many Symptoms of Dysphagia  

Dysphagia can result if there is a problem with any of the numerous mechanisms involved with swallowing from a weakened tongue to a miscommunication along nerve pathways. Difficulties often originate in the esophagus.  Not only can dysphagia cause significant discomfort, the inability to swallow can also cause significant health complications. Those living with dysphagia are at a significantly increased risk of choking, chronic malnutrition, dehydration, and aspirational pneumonia. The symptoms of dysphagia can vary depending on the cause of the condition.

Feeling Like Food Gets Stuck

With dysphagia, you may experience the sensation of having food stuck in some area of your throat or behind your breastbone. This sensation can be recurring or persistent, mild or severe. The symptoms could indicate problems with chewing, a narrowing of the pharynx, physical blockage, or a neurological disruption of the smooth muscles that move food toward the stomach.

Generally speaking, dysphasia that occurs within seconds of trying to swallow is the result of a dysfunction in the muscles that keep food out of the nose and voice box during swallowing. Food entering the larynx often causes coughing or choking. Coughing is your body's way of keeping irritants, including the foods you eat, out of your respiratory system. When functioning properly, a flap of skin called your epiglottis blocks food and stomach contents from entering your lungs. If dysphagia is disrupting function, there is an increased risk of aspiration.  

Difficulty Starting a Swallow

Swallowing is one of the functions in our bodies that can be automatic or controlled. Many people living with dysphagia find that the mechanisms required for swallowing are unresponsive or delayed. When the swallowing mechanisms resist activation, there is an increased risk of choking and subsequently aspirating food, liquids, or saliva into the lungs which could result in recurring respiratory infection.

Pain While Swallowing

There are many conditions that cause pain when swallowing. Temporary pain can often accompany a viral or bacterial infection. If swallowing proves painful but there is no indication of infection, painful swallowing (odynophagia) could be an indication of dysphagia. The pain of dysphagia is most commonly felt in the throat, neck, or chest and could suggest inflammation of the esophagus, a common cause of painful swallowing.  

Regurgitation of Swallowed Foods

Many people with dysphasia have no noticeable issues swallowing but have difficulty keeping food down once eaten. Food and liquids can come back up through the throat, nose, or mouth soon after being swallowed. Regurgitated food often tastes the same as when it was first swallowed. The regurgitation of bitter or sour-tasting foods and liquids suggest that at least a portion of the regurgitated substance had made its way to the stomach. The regurgitation of food that has reached the stomach may indicate a reflux disorder.

Swallowing Difficulties Should Be Evaluated 

The symptoms of dysphagia could also include a hoarse voice, weight loss, and frequent heartburn. When swallowing difficulties are severe, dysphagia can cause drooling. If you suspect your symptoms could be caused by dysphagia, it's important to consult your health care provider. Left untreated, dysphagia can result in significant complications, including weight loss, dehydration, and aspiration pneumonia.  

The treatment for dysphagia depends on whether the condition originates in the mouth, throat, or esophagus. Depending on the cause of your swallowing difficulties, your physician may recommend working with a team of healthcare specialists, which could include a neurologist, speech pathologist, or ear, nose, and throat specialist (ENT).
