Causes & Risk Factors
Several factors can contribute to Esophageal Achalasia.
The exact cause of achalasia remains unknown, but researchers believe it stems from damage to the nerves that control esophageal muscle function.
The exact cause of achalasia remains unknown, but researchers believe it stems from damage to the nerves that control esophageal muscle function. The enteric nervous system, which manages digestive tract movements, appears to malfunction in people with this condition. Specifically, the nerve cells that signal the lower esophageal sphincter to relax and coordinate swallowing become damaged or destroyed over time.
Several theories attempt to explain this nerve damage.
Several theories attempt to explain this nerve damage. Some scientists suspect an autoimmune reaction where the body's immune system mistakenly attacks its own nerve cells. Others point to viral infections as potential triggers, though no specific virus has been definitively linked to achalasia. Genetic factors may also play a role, as rare familial cases have been reported, suggesting some people might inherit a predisposition to developing the condition.
Secondary achalasia can result from other medical conditions that damage the esophagus or its nerve supply.
Secondary achalasia can result from other medical conditions that damage the esophagus or its nerve supply. Chagas disease, caused by a parasitic infection common in parts of South America, can lead to achalasia-like symptoms. Certain cancers, particularly those affecting the gastroesophageal junction, can also mimic achalasia by causing similar blockage patterns. However, the vast majority of achalasia cases are primary, meaning they occur without any identifiable underlying cause.
Risk Factors
- Age between 30-60 years old
- Family history of achalasia (rare)
- Previous Chagas disease infection
- Autoimmune disorders
- Certain genetic variations
- Living in areas where Chagas disease is endemic
- History of esophageal injury or surgery
- Exposure to certain viral infections
Diagnosis
How healthcare professionals diagnose Esophageal Achalasia:
- 1
Diagnosing achalasia typically begins when someone visits their doctor complaining of progressive difficulty swallowing.
Diagnosing achalasia typically begins when someone visits their doctor complaining of progressive difficulty swallowing. The physician will take a detailed history about symptoms, paying particular attention to how swallowing problems have developed over time. A physical examination follows, though achalasia rarely produces obvious external signs. The doctor will likely ask about weight loss, chest pain, and whether liquids or solids cause more trouble.

Several specialized tests help confirm the diagnosis.
Several specialized tests help confirm the diagnosis. A barium swallow study involves drinking a chalky liquid that shows up on X-rays, allowing doctors to watch how the esophagus functions in real-time. In achalasia, the barium typically pools in the esophagus above a narrowed area, creating a characteristic "bird's beak" appearance on the X-ray. An upper endoscopy lets doctors look directly inside the esophagus and stomach using a flexible camera, helping rule out cancers or other structural problems that might mimic achalasia.

The gold standard test for achalasia is esophageal manometry, which measures pressure and coordination in the esophageal muscles.
The gold standard test for achalasia is esophageal manometry, which measures pressure and coordination in the esophageal muscles. During this procedure, a thin tube with pressure sensors is passed through the nose into the esophagus. Patients swallow small amounts of water while the device records muscle contractions and sphincter function. This test can distinguish achalasia from other swallowing disorders and help classify the specific type of achalasia, which guides treatment decisions. Additional tests like CT scans might be ordered to rule out secondary causes of achalasia-like symptoms.
Complications
- Left untreated, achalasia can lead to several serious complications that significantly impact health and quality of life.
- The most concerning immediate risk is aspiration pneumonia, which occurs when food or liquids that back up in the esophagus are inhaled into the lungs.
- This can cause severe lung infections, particularly dangerous for older adults or people with compromised immune systems.
- Malnutrition and significant weight loss often develop as eating becomes increasingly difficult and painful.
- Long-term complications include an increased risk of esophageal cancer, though this remains relatively rare.
- The chronic irritation and food stasis in the esophagus may contribute to cellular changes over time.
- Megaesophagus, a condition where the esophagus becomes severely enlarged and twisted, can develop in advanced cases, making treatment more challenging.
- Some patients also experience chronic cough and sleep disruption from nighttime regurgitation.
- With proper treatment, however, most people with achalasia can avoid these complications and maintain good nutritional status and quality of life.
Prevention
- Achalasia cannot be prevented because its underlying causes remain largely unknown and appear to involve factors beyond personal control.
- Unlike some digestive conditions that can be prevented through lifestyle changes, achalasia seems to develop due to nerve damage that occurs for unclear reasons.
- No specific dietary choices, behaviors, or environmental modifications have been proven to reduce the risk of developing this condition.
- For people living in areas where Chagas disease is common, preventing infection with the parasitic organism Trypanosoma cruzi can help avoid secondary achalasia.
- This involves controlling the insects that spread the parasite and avoiding contaminated food or blood transfusions.
- However, Chagas disease is extremely rare in North America and Europe, making this prevention strategy irrelevant for most people.
- While primary prevention isn't possible, early recognition and treatment of symptoms can prevent serious complications.
- People who notice progressive difficulty swallowing should seek medical evaluation rather than assuming the problem will resolve on its own.
- Prompt diagnosis and appropriate treatment can preserve esophageal function and prevent complications like aspiration pneumonia or severe malnutrition.
Treatment for achalasia focuses on reducing the pressure in the lower esophageal sphincter and improving food passage into the stomach.
Treatment for achalasia focuses on reducing the pressure in the lower esophageal sphincter and improving food passage into the stomach. Since the underlying nerve damage cannot be reversed, all treatments aim to manage symptoms rather than cure the condition. The approach chosen depends on the patient's age, overall health, and severity of symptoms.
Medications represent the least invasive option but offer limited long-term success.
Medications represent the least invasive option but offer limited long-term success. Calcium channel blockers like nifedipine or nitrates can temporarily relax the esophageal sphincter, though their effects usually diminish over time. Botulinum toxin injections directly into the sphincter muscle provide temporary relief by paralyzing the muscle, but repeat treatments are needed every few months.
Minimally invasive procedures offer more durable results.
Minimally invasive procedures offer more durable results. Pneumatic dilation involves inserting a balloon into the lower esophageal sphincter and inflating it to stretch or tear the muscle fibers, reducing pressure. This outpatient procedure provides good symptom relief for several years in many patients. Laparoscopic Heller myotomy, performed through small incisions, involves surgically cutting the muscle fibers of the lower esophageal sphincter. This procedure often includes an anti-reflux procedure to prevent post-operative heartburn.
Peroral endoscopic myotomy (POEM) represents the newest treatment option.
Peroral endoscopic myotomy (POEM) represents the newest treatment option. During this procedure, doctors access the esophageal muscle through the mouth using an endoscope, avoiding external incisions entirely. POEM has shown excellent success rates with faster recovery times compared to traditional surgery. Recent advances in treatment selection use high-resolution manometry to classify achalasia into subtypes, helping doctors choose the most appropriate intervention for each individual patient.
Living With Esophageal Achalasia
Living successfully with achalasia requires adapting eating habits and maintaining regular medical follow-up. Many people find that eating smaller, more frequent meals works better than three large meals per day. Chewing food thoroughly, eating slowly, and drinking warm liquids can help food pass more easily. Some patients discover that certain food textures work better than others, and keeping a food diary can help identify problem foods.
