Causes, Symptoms, and Treatment of Swallowing Difficulty (Dysphagia)

Swallowing Difficulty (Dysphagia)

Although swallowing may seem simple, the swallowing process requires highly complex and delicate coordination. This process takes place through the collaborative work of many muscles and nerves in the brain, nervous system, mouth, throat, and esophagus. A disruption at any point in this system can cause impairments in swallowing function. While dysphagia is sometimes a temporary condition, in some individuals it can be the first sign of serious diseases. Neurological disorders such as stroke, Parkinson's disease, multiple sclerosis (MS), and Alzheimer's, as well as esophageal strictures, tumors, or musculoskeletal structural disorders, are among the causes of dysphagia. Additionally, gastroesophageal reflux disease (GERD), anxiety disorders, and the side effects of certain medications can negatively affect the swallowing process.

Dysphagia can affect all age groups, but it is particularly more common in the elderly, stroke survivors, individuals with neurological diseases, and children. It may manifest with symptoms such as a feeling of food getting stuck in the throat, pain or difficulty while swallowing, hoarseness, speech disorders, coughing, or a choking reflex. Furthermore, weight loss, malnutrition, and recurrent pulmonary infections are counted among the serious complications that dysphagia can lead to.

The diagnostic process begins with taking a detailed medical history of the patient. Afterward, a detailed analysis is performed using physical examination, videofluoroscopic swallowing studies (VFSS), endoscopic evaluations, and imaging techniques. While medical treatment or lifestyle changes aimed at reflux may be sufficient for some patients, other cases may require surgical intervention or rehabilitation programs conducted with speech and swallowing therapists. Dysphagia is a serious problem that directly affects the quality of life. Therefore, consulting a healthcare professional without delay when symptoms begin is of great importance both for early diagnosis and for preventing potential complications.

What is Swallowing Difficulty (Dysphagia)?

Swallowing difficulty, medically known as dysphagia, is the condition of experiencing difficulty during the passage of food or liquids from the mouth to the stomach. Any disorder that may occur in the muscular or nervous system can lead to a flaw in the swallowing process. Among the causes of swallowing difficulty are neurological diseases, muscle disorders, and anatomical problems. In particular, disorders related to the nervous system, and structural disorders such as tumors or strictures, are among the underlying causes of swallowing problems. Swallowing difficulty in children can generally develop due to congenital disorders, muscle weakness, or neurological causes. Especially if difficulty while eating recurs frequently, an expert evaluation is essential.

What Are the Symptoms of Swallowing Difficulty?

The symptoms of swallowing difficulty are generally a feeling of food getting stuck in the throat, coughing with swallowing, and weight loss. Although these symptoms sometimes follow a mild course, they can lead to quite serious consequences in some patients. At the same time, individuals experiencing difficulty in swallowing may struggle to consume solid and liquid foods. The symptoms of swallowing difficulty vary depending on which stage of the swallowing process the problem is experienced in. Among the types of dysphagia, there are two main categories: oropharyngeal dysphagia and esophageal dysphagia. In the type called oropharyngeal dysphagia, the person may have difficulty keeping food in their mouth or food may enter the trachea. In the case of esophageal dysphagia, it is felt that the food is stuck in the esophagus.

How Does Swallowing Difficulty Occur?

Normally, the swallowing process is a reflexive and unconscious process. Swallowing takes place in three stages: oral, pharyngeal, and esophageal. In the oral phase, foods are chewed and prepared for swallowing. In the pharyngeal phase, food or drink is directed into the esophagus with the trachea closed. A problem experienced in any phase causes swallowing difficulty. For example, nervous system disorders can prevent these muscles from working in coordination. Anxiety can create swallowing difficulty because stress and tension lead to contractions in the throat muscles. Among the causes of swallowing difficulty are also conditions such as stroke, Parkinson's disease, and reflux. Alzheimer's can present with swallowing difficulty because as the disease progresses, the swallowing reflex weakens.

How is Swallowing Difficulty Diagnosed?

The physician listens to how long the complaint has been ongoing, whether the problem is experienced with solid or liquid foods, and the person's general health history. Then, the problem is detailed through physical examination and various imaging methods. The swallowing difficulty test is generally performed with a barium swallow, endoscopy, and swallowing assessment tests. In the swallowing difficulty test, the patient is made to swallow foods of different consistencies under radiological imaging to evaluate swallowing function. Methods such as endoscopy, manometry, and barium swallow are other tools used in diagnosis. Complaints of swallowing difficulty in children are handled with greater sensitivity. Especially if a 5-year-old child is experiencing swallowing difficulty, whether there is an underlying neurological or structural problem is investigated carefully.

How is Swallowing Difficulty Treated?

Dysphagia treatment is shaped in line with the diagnosed cause. First, changes are made in dietary habits. In dysphagia meal planning, thickened liquids, pureed foods, and easily chewable foods are preferred. If there is a reflux-induced problem, medications that reduce stomach acid are prescribed. If a neurological disease is in question, personalized dysphagia exercises are applied by speech and swallowing therapists. Physical rehabilitation holds an important place within the scope of dysphagia treatment. If there is a tumor or stricture leading to food getting stuck in the esophagus, surgical methods can be resorted to. When the causes of dysphagia are correctly identified, symptoms can be largely alleviated with appropriate treatment.

Frequently Asked Questions

Although the causes of swallowing difficulty are sometimes temporary conditions, they can also be a sign of underlying serious diseases. Difficulty swallowing can be a sign of many different diseases such as neurological, musculoskeletal, digestive system, and structural problems. In particular, nervous system disorders such as Parkinson's disease, stroke, ALS, and multiple sclerosis are among the most common causes. When a 5-year-old child experiences swallowing difficulty, developmental delay or a muscle coordination problem can be considered. Additionally, reflux disease, esophageal strictures, tumors, and certain autoimmune diseases can also lead to this condition. All these possibilities need to be reviewed before a diagnosis is made. Not every swallowing problem means cancer, but cancers occurring in regions such as the esophagus, larynx, or base of the tongue can cause dysphagia. If swallowing difficulty is worsening over time, accompanied by pain and weight loss, advanced examination must definitely be performed. Early diagnosis in such cases can be life-saving. A foreign body or fullness sensation in the throat is generally reflux-induced. Acid can escape upward from the esophagus and cause irritation in the throat. However, anxiety, neck muscle tension, and certain thyroid diseases can also create this feeling. Rarely, tumoral formations or structures like cysts can also be the cause of fullness. When a sore throat occurs together with swallowing difficulty, it may be infection-induced. Stress and anxiety disorders can cause difficulty swallowing. As a result of the contraction of throat muscles and irregular breathing, the person has difficulty swallowing foods normally. In stress-induced dysphagia, there is usually no structural problem and the symptoms are temporary. The swallowing reflex is under the control of the brainstem and surrounding nerve networks. Conditions such as stroke, trauma, brain tumor, or nerve degeneration can affect the swallowing reflex. Since the risk of food aspiration (food entering the lung) is high in such patients, a dysphagia dietary plan must be made. Difficulties experienced during swallowing range widely from infections to tumors. Among dysphagia symptoms are coughing while eating, pain while swallowing, and malnutrition. Sometimes throat infections can temporarily cause this condition, but long-lasting swallowing problems can be a sign of more serious problems such as neurological diseases, muscle diseases, anatomical disorders, or cancer. At the same time, anxiety can increase the complaint of swallowing difficulty, and it is frequently seen in individuals under stress. The department to apply to first is generally the Ear, Nose, and Throat (ENT) outpatient clinic. After evaluating with a detailed examination and necessary tests, the ENT specialist can refer the patient to neurology, gastroenterology, or speech and language therapy. A burning sensation in the throat is mostly associated with gastroesophageal reflux. When stomach acid flows back into the esophagus, both irritation and swallowing difficulty can emerge. Sometimes infections, especially viral pharyngitis, also lead to these symptoms. If complaints have been ongoing for a long time, endoscopic examination is recommended. Difficulty while swallowing solid foods is generally associated with mechanical causes such as esophageal strictures, tumors, or muscle spasms. In this case, food feels as if it is getting stuck in the esophagus. This symptom is important and requires expert evaluation without delay.

If you are experiencing a feeling of food getting stuck in your throat while eating or drinking water, if you are coughing frequently for no apparent reason, or if an uncomfortable feeling as if something is getting stuck in your throat during swallowing occurs, these symptoms should not be ignored. Such complaints may be temporary in some cases; however, if the symptoms recur regularly or worsen over time, an evaluation by an Ear, Nose, and Throat department specialist is definitely required.

Swallowing difficulty (dysphagia) can develop depending on different diseases, and unless the cause is correctly identified, it can negatively affect both your physical health and your social life. Sometimes a simple reflux problem leads to dysphagia, while at other times it can be a harbinger of more serious neurological or structural diseases.
