Gastroesophageal reflux disease occurs when stomach contents repeatedly flow back into the oesophagus. Over time, this can cause irritation and inflammation. In some individuals, ongoing reflux may lead to complications such as narrowing of the oesophagus due to scar tissue, making it difficult to swallow food. Common associated symptoms include heartburn, sour-tasting fluid in the mouth, chest discomfort, and regurgitation. However, not everyone with reflux experiences typical heartburn. Persistent difficulty swallowing should not automatically be attributed to acid reflux. Medical assessment is important to identify the actual cause.
An oesophageal stricture is a narrowing of the tube that carries food from the throat to the stomach. It may develop due to chronic inflammation, acid reflux, or other conditions affecting the oesophageal lining. People with an oesophageal stricture may initially experience difficulty swallowing solid foods, with symptoms sometimes becoming progressively worse. Treatment depends on the cause and severity. In selected cases, an endoscopic procedure called oesophageal dilation may be recommended to widen the narrowed area.
The oesophagus uses coordinated muscle contractions to move food towards the stomach. The lower oesophageal sphincter also needs to relax appropriately to allow food to enter the stomach. In achalasia, this relaxation is impaired, and normal movement of the oesophagus is disrupted. As a result, food and liquids may remain in the oesophagus rather than passing into the stomach normally. Symptoms may include difficulty swallowing both solids and liquids, regurgitation of undigested food, chest discomfort, and unintentional weight loss. Other motility disorders can also affect swallowing. Depending on the suspected condition, tests such as oesophageal manometry may be required to assess muscle function.
Eosinophilic oesophagitis is a chronic inflammatory condition in which a type of white blood cell called an eosinophil accumulates in the oesophagus. It can cause difficulty swallowing, a sensation of food sticking, and episodes in which food becomes lodged in the oesophagus. It is often associated with allergic conditions such as asthma, eczema, or food allergies, although presentations vary. Diagnosis generally involves upper gastrointestinal endoscopy and biopsies of the oesophageal lining. Treatment may include dietary management under professional guidance, acid-suppressing medication, swallowed topical corticosteroids, or oesophageal dilation when narrowing is present.
Swallowing requires coordination between the brain, nerves, and muscles of the mouth and throat. Conditions that affect this coordination can cause oropharyngeal dysphagia. Possible causes include stroke, Parkinson’s disease, certain neuromuscular disorders, and other neurological conditions. Symptoms may include difficulty initiating a swallow, coughing or choking during meals, drooling, a wet-sounding voice after swallowing, or food remaining in the mouth. These symptoms require appropriate assessment because swallowing problems can increase the risk of aspiration, where food or liquid enters the airway.
In some cases, difficulty swallowing may occur because of an abnormal growth in the oesophagus or surrounding structures. Progressively worsening difficulty swallowing, particularly when it begins with solid foods and later affects liquids, requires prompt medical evaluation. Other concerning symptoms may include unintentional weight loss, persistent chest discomfort, or bleeding. These symptoms do not necessarily indicate cancer, but they should not be ignored. Early investigation can help identify the underlying cause and determine the appropriate next steps.
Dysphagia symptoms can vary depending on the underlying condition and the part of the swallowing process affected.
Common symptoms include:
Some people experience symptoms only occasionally, while others notice them during most meals.
Persistent symptoms, even when mild, deserve medical attention. Difficulty swallowing should not be considered a normal part of aging.
Certain symptoms require immediate medical attention rather than waiting for a routine appointment.
Arrange prompt medical assessment if swallowing difficulty is new, persistent, progressively worsening, or accompanied by unintentional weight loss, painful swallowing, vomiting, or blood in vomit or stool. Early evaluation can help prevent complications such as dehydration, malnutrition, and aspiration-related lung problems.
The first step in diagnosing swallowing difficulties is a detailed clinical assessment. A gastroenterologist will review your symptoms, medical history, medications, and the circumstances in which swallowing becomes difficult. Depending on the suspected cause, one or more of the following investigations may be recommended.
An upper gastrointestinal endoscopy, also called an upper GI endoscopy or OGD, uses a thin, flexible tube with a camera to examine the oesophagus, stomach, and the first part of the small intestine. It can help identify inflammation, narrowing, ulcers, abnormal growths, and other structural problems. Tissue samples may also be collected when necessary.
During a barium swallow study, the patient swallows a contrast liquid while X-ray images are taken. This helps clinicians assess the shape and movement of the oesophagus and identify certain structural or swallowing abnormalities. A related examination, called a videofluoroscopic swallowing study, may be used when the main concern involves the mouth and throat phases of swallowing.
Oesophageal manometry measures the pressure and coordination of muscle contractions within the oesophagus. It may be recommended when a motility disorder, such as achalasia, is suspected or when other investigations have not adequately explained the symptoms.
Depending on the clinical findings, further investigations may include biopsies, imaging, or a formal swallowing assessment by a speech and language therapist with appropriate dysphagia expertise.
Not every patient needs every test. The choice depends on the location of the swallowing difficulty, associated symptoms, and findings from the initial assessment.
Difficulty swallowing treatment depends on the underlying cause. There is no single treatment that works for every form of dysphagia, which is why accurate diagnosis is essential.
Medication: When swallowing difficulty is related to acid reflux or inflammation, medication may be recommended to control acid production or treat the underlying condition. Specific inflammatory or motility disorders may require different treatments. Medication should be selected by a healthcare professional based on the diagnosis.
Endoscopic Procedures: For selected patients with an oesophageal stricture, endoscopic dilation may help widen the narrowed area and improve the passage of food. Food impaction may require urgent endoscopic removal. Other conditions may need specialised endoscopic or surgical treatment depending on the diagnosis.
Conditions such as achalasia may require procedures that help food pass more easily into the stomach. Treatment options can include pneumatic dilation, peroral endoscopic myotomy (POEM), or surgical myotomy in suitable patients.
The choice depends on the specific disorder, its severity, and the patient’s overall health.
When dysphagia affects the mouth or throat, a swallowing specialist may recommend techniques or exercises suited to the individual’s condition. Food consistency or liquid thickness may also need adjustment following an appropriate swallowing assessment. These changes should be guided by a qualified professional because unsuitable modifications can affect nutrition, hydration, and swallowing safety. Dietary changes alone should not replace medical evaluation when swallowing difficulty is persistent or worsening.
Not every cause of dysphagia can be prevented. However, certain measures may help manage underlying risk factors and support swallowing safety.
If swallowing feels uncomfortable, food repeatedly seems to get stuck, or symptoms are becoming more frequent, consult a gastroenterologist for an appropriate evaluation. A specialist can help determine whether the problem is related to acid reflux, oesophageal narrowing, a motility disorder, inflammation, or another condition. Timely diagnosis can guide treatment and help reduce the risk of complications. At Progress Gastro Care, patients can seek specialist assessment for persistent digestive and oesophageal symptoms, with further investigations and treatment recommendations based on individual clinical needs.
Do not ignore difficulty swallowing or assume it will resolve on its own. Recognising the warning signs and seeking medical care at the right time can make an important difference to your health and quality of life.
Difficulty swallowing may result from acid reflux, oesophageal narrowing, achalasia, eosinophilic oesophagitis, neurological conditions, or other disorders affecting swallowing.
Dysphagia symptoms include food feeling stuck in the throat or chest, difficulty swallowing solids or liquids, coughing during meals, painful swallowing, and regurgitation.
Seek medical evaluation if swallowing difficulty is persistent, worsening, or accompanied by painful swallowing or unexplained weight loss. Inability to swallow saliva or breathing difficulties requires emergency care.
Diagnosis may involve an upper GI endoscopy, barium swallow study, oesophageal manometry, or a specialised swallowing assessment, depending on the suspected cause.
Difficulty swallowing treatment depends on the cause and may include medication, endoscopic procedures, specialised swallowing therapy, or surgery. A medical evaluation is essential to determine the appropriate approach.
