Esophageal stricture is a condition where the esophagus (the muscular tube that carries food and liquids from the throat to the stomach) narrows, making it difficult for food and drink to pass through smoothly. Imagine a straw that’s been squeezed in the middle; food and liquids can no longer flow through freely, causing discomfort and potential nutritional issues. For older adults, who may already struggle with various health concerns, esophageal strictures can significantly impact their quality of life.

How common is esophageal stricture in the elderly?
Esophageal strictures are a common issue among older adults, with studies estimating that about 1 in 10 cases of dysphagia (difficulty swallowing) in the elderly are due to strictures. Gastroesophageal Reflux Disease (GERD) is a common cause, especially as GERD affects up to 20% of adults over 65, with 10-20% of these individuals potentially developing strictures over time. These statistics highlight the importance of early detection and management to prevent the escalation of this condition among seniors.

Risk factors for esophageal strictures
Several risk factors make elderly individuals particularly susceptible to esophageal strictures:
- Chronic acid reflux, a.k.a. Gastroesophageal Reflux Disease (GERD)
Repeated exposure of the esophageal lining to stomach acid can damage and scar the tissues. - Hiatal hernia
This occurs when part of the stomach pushes up through the diaphragm, increasing the likelihood of acid reflux. - Medications
Certain medications, including NSAIDs and bisphosphonates (for osteoporosis), can irritate the esophagus. - Radiation therapy
Those who have undergone radiation treatment for cancers near the esophagus are at a higher risk of developing strictures. - Lifestyle factors
Smoking, excessive alcohol intake, and a diet high in acidic foods can exacerbate acid reflux, increasing stricture risk.
Causes of esophageal strictures
Esophageal strictures in the elderly can be caused by both internal and external factors:
- GERD
The most common cause, where chronic acid exposure leads to inflammation and scarring. - Swallowed substances
Certain substances, like cleaning agents or other caustic liquids, can damage the esophagus if ingested. - Infections and diseases
Some infections (like Candida or herpes) or conditions (like scleroderma) contribute to esophageal inflammation and subsequent scarring.
Symptoms of esophageal stricture
There are several common symptoms of esophageal stricture that one can take note of:
- Difficulty swallowing (Dysphagia)
Initially with solid foods, but as the stricture worsens, even liquids can become hard to swallow. - Painful swallowing (Odynophagia)
Eating and drinking can cause discomfort or pain. - Regurgitation of food
Partially digested food may come back up, leading to malnutrition and weight loss. - Frequent heartburn
Persistent acid reflux may cause burning sensations. - Unexplained weight loss
Due to poor intake from difficulty swallowing.
Complications of esophageal stricture
Knowing the symptoms allows you to seek medical assistance early, if left unnoticed or untreated, esophageal strictures can lead to other complications, such as:
- Aspiration pneumonia
When food or liquid enters the lungs due to regurgitation, causing infection of the lungs. - Malnutrition
Difficulty in swallowing reduces appetite and food intake, affecting nutritional status, especially in frail seniors. - Dehydration
Reduced fluid intake may result in dehydration, which can further complicate existing health conditions.
How should caregivers respond?
Caregivers play a pivotal role in managing esophageal strictures. In the event when caregivers suspect the elderly suffers esophageal stricture, they can take the following actions and observations:
- Observing meal intake
Monitor food and liquid intake, noting any issues with swallowing or discomfort. - Encouraging small, frequent meals
This reduces pressure on the esophagus and may minimise discomfort. - Adapting food consistency
Pureed or soft foods can ease swallowing difficulties. - Promptly reporting symptoms
Signs of choking, weight loss, or dehydration should be reported to healthcare providers for timely intervention.
Treatment options for esophageal strictures
Treatment may vary based on the cause and severity, but generally, the treatments may include:
- Esophageal dilation
A procedure where a balloon or dilator stretches the esophagus to allow easier passage of food. - Medications
Proton pump inhibitors (PPIs) are commonly prescribed to manage acid reflux and prevent further scarring. - Surgical options
In severe cases, surgery may be required to remove or bypass the narrowed segment.
While PPIs are effective, long-term use can lead to side effects like increased fracture risk (due to reduced calcium absorption), vitamin B12 deficiency, and possible kidney issues. It is crucial for healthcare providers to monitor elderly patients on these medications and consider periodic reassessment.

Prevention strategies for esophageal stricture
For elderly individuals who are not suffering esophageal stricture, it is equally important to prevent it from happening. Several preventive steps are listed below:
- Managing GERD
Lifestyle changes, such as weight management, reducing acidic foods, and avoiding late-night meals, can lessen GERD symptoms. - Avoiding caustic substances
Education around household products and medications helps prevent accidental ingestion of harmful substances. - Regular monitoring
For those at higher risk, regular esophageal exams can help detect early signs of narrowing and prompt timely intervention.
Conclusion
Esophageal strictures are a significant health concern in elderly populations, impacting their ability to eat, stay nourished, and enjoy daily life. While the condition is treatable, early detection, lifestyle adjustments, and proactive management are key to preserving the quality of life. By understanding and addressing the risk factors, symptoms, and treatment options, caregivers and healthcare professionals can help elderly individuals maintain a comfortable, fulfilling life, free from the constraints of esophageal strictures.
