Causes & Risk Factors

Several factors can contribute to Achalasia.

The exact cause of achalasia remains largely mysterious to medical researchers, though they have identified several important clues about how this condition develops.

The exact cause of achalasia remains largely mysterious to medical researchers, though they have identified several important clues about how this condition develops. The primary problem appears to be damage to the nerve cells that control the esophageal muscles, particularly those in the myenteric plexus, a network of nerves embedded in the esophageal wall. When these nerves stop working properly, they can no longer coordinate the complex sequence of muscle contractions needed for normal swallowing.

Several theories exist about what triggers this nerve damage.

Several theories exist about what triggers this nerve damage. Some researchers believe that viral infections, particularly herpes simplex virus, may attack the esophageal nerves in genetically susceptible individuals. Others suspect that achalasia might be an autoimmune condition, where the body's immune system mistakenly attacks its own nerve tissue. This theory gains support from the fact that some people with achalasia also have other autoimmune conditions.

A small percentage of achalasia cases, known as secondary achalasia, result from other diseases that affect the esophagus.

A small percentage of achalasia cases, known as secondary achalasia, result from other diseases that affect the esophagus. Chagas disease, caused by a parasite common in South America, can damage esophageal nerves and create symptoms identical to primary achalasia. Certain cancers, particularly those involving the gastroesophageal junction, can also block normal esophageal function and mimic achalasia symptoms. These secondary causes are why doctors often perform thorough testing to rule out other conditions before confirming an achalasia diagnosis.

Risk Factors

Family history of achalasia or related esophageal disorders
Living in or traveling to areas where Chagas disease is common
Having other autoimmune conditions
Previous viral infections affecting the chest or esophagus
Being between ages 30-60 years
Having certain genetic variations affecting nerve function
History of gastroesophageal reflux disease
Exposure to certain environmental toxins

Diagnosis

How healthcare professionals diagnose Achalasia:

1
Diagnosing achalasia typically begins when someone visits their doctor complaining of persistent swallowing difficulties, especially if they notice problems with both solids and liquids.
Diagnosing achalasia typically begins when someone visits their doctor complaining of persistent swallowing difficulties, especially if they notice problems with both solids and liquids. The doctor will take a detailed history about symptoms, their progression, and any family history of similar problems. A physical examination usually appears normal, which is why specialized tests are essential for confirming the diagnosis.
2
The gold standard test for achalasia is esophageal manometry, a procedure that measures the pressure and coordination of muscle contractions throughout the esophagus.
The gold standard test for achalasia is esophageal manometry, a procedure that measures the pressure and coordination of muscle contractions throughout the esophagus. During this test, a thin, flexible tube with pressure sensors is passed through the nose and down into the esophagus and stomach. Patients swallow small amounts of water while the sensors record how well the esophageal muscles contract and whether the lower esophageal sphincter relaxes properly. In achalasia, this test typically shows absent or poorly coordinated contractions and incomplete relaxation of the lower sphincter.
3
Other important diagnostic tests include a barium swallow study, where patients drink a chalky liquid that shows up on X-rays, allowing doctors to watch how food moves through the esophagus.
Other important diagnostic tests include a barium swallow study, where patients drink a chalky liquid that shows up on X-rays, allowing doctors to watch how food moves through the esophagus. This test often reveals the characteristic "bird's beak" appearance of achalasia, where the esophagus is dilated above a narrowed area at the junction with the stomach. An upper endoscopy may also be performed to rule out cancer or other structural abnormalities, and to assess the degree of esophageal inflammation or food retention. Some doctors may order additional tests like CT scans or blood work to exclude secondary causes of achalasia-like symptoms.

Complications

The most common complications of untreated achalasia result from food and liquids remaining in the esophagus for extended periods.
This can lead to aspiration pneumonia when regurgitated material enters the lungs, particularly during sleep.
Many patients experience significant weight loss and malnutrition due to their inability to eat normally.
The constant presence of food in the esophagus can also cause chronic inflammation and increase the risk of developing esophageal cancer, though this remains relatively rare.
Long-term achalasia can cause permanent changes to the esophagus structure, including significant dilation and loss of muscle function.
Some patients develop a condition called megaesophagus, where the esophagus becomes severely enlarged and twisted.
Even after successful treatment, patients with advanced achalasia may continue to experience some swallowing difficulties.
However, with proper medical care and timely intervention, most people with achalasia can avoid these serious complications and maintain a good quality of life.

Prevention

Unfortunately, there are no proven methods to prevent achalasia since its exact cause remains unknown.
The condition appears to develop spontaneously in most people, without clear environmental triggers or lifestyle factors that increase risk.
Unlike many digestive disorders, achalasia does not seem to be related to diet, stress, or other modifiable behaviors.
For people living in areas where Chagas disease is endemic, taking precautions against the insects that spread this infection may help prevent secondary achalasia.
This includes using insect repellent, sleeping under bed nets, and improving housing conditions to reduce exposure to triatomine bugs.
However, Chagas-related achalasia represents only a small fraction of cases worldwide.
The most practical approach focuses on early recognition and prompt treatment rather than prevention.
People with a family history of achalasia should be aware of the symptoms and seek medical attention quickly if swallowing problems develop.
Early diagnosis and treatment can prevent many of the complications associated with advanced achalasia, such as severe weight loss, aspiration pneumonia, and irreversible esophageal damage.

Treatment Approaches

Treatment for achalasia focuses on reducing the pressure in the lower esophageal sphincter to allow food and liquids to pass more easily into the stomach.

Treatment for achalasia focuses on reducing the pressure in the lower esophageal sphincter to allow food and liquids to pass more easily into the stomach. Since the underlying nerve damage cannot be repaired, all current treatments work by physically or chemically disrupting the tight sphincter muscle. The choice of treatment depends on the patient's age, overall health, symptom severity, and personal preferences.

Medications represent the most conservative treatment option, though they typically provide only modest symptom relief.

Medications represent the most conservative treatment option, though they typically provide only modest symptom relief. Calcium channel blockers like nifedipine and nitrates can help relax the lower esophageal sphincter temporarily. Some doctors prescribe muscle relaxants or inject botulinum toxin directly into the sphincter during endoscopy. While these approaches are less invasive, they usually require frequent repeat treatments and work best for patients who cannot undergo more definitive procedures.

SurgicalMedication

Pneumatic dilation offers a more effective non-surgical option, involving the inflation of a large balloon inside the lower esophageal sphincter to forcibly stretch and partially tear the muscle fibers.

Pneumatic dilation offers a more effective non-surgical option, involving the inflation of a large balloon inside the lower esophageal sphincter to forcibly stretch and partially tear the muscle fibers. This outpatient procedure provides good symptom relief in about 85% of patients, though some may need repeat dilations over time. The main risk is perforation of the esophagus, which occurs in less than 5% of cases but requires immediate surgical repair.

Surgical

Surgical treatments provide the most durable symptom relief for most patients with achalasia.

Surgical treatments provide the most durable symptom relief for most patients with achalasia. Laparoscopic Heller myotomy, performed through small incisions in the abdomen, involves cutting the muscle fibers of the lower esophageal sphincter. Surgeons typically combine this with a fundoplication, where part of the stomach is wrapped around the esophagus to prevent acid reflux. A newer option called peroral endoscopic myotomy (POEM) uses an endoscope passed through the mouth to cut the sphincter muscle from the inside. Both surgical approaches achieve excellent results in over 90% of patients, with POEM showing particular promise for long-term symptom control.

Living With Achalasia

Living successfully with achalasia requires learning new eating habits and strategies to manage symptoms. Many patients find that eating smaller, more frequent meals works better than three large meals per day. Chewing food thoroughly, eating slowly, and drinking plenty of fluids during meals can help food pass through the esophagus more easily. Some people discover that certain positions, such as raising their arms overhead or standing while eating, can help gravity move food toward the stomach.

Dietary modifications often become necessary, with many patients avoiding foods that are particularly difficult to swallow.Dietary modifications often become necessary, with many patients avoiding foods that are particularly difficult to swallow. Common problematic foods include bread, rice, meat, and carbonated beverages. Softer foods, pureed meals, and liquids typically cause fewer problems. Some patients benefit from warming foods slightly, as this can help relax the esophageal muscles. Avoiding large meals before bedtime can reduce the risk of regurgitation during sleep.

Emotional support and practical resources play crucial roles in managing achalasia successfully.Emotional support and practical resources play crucial roles in managing achalasia successfully. Many patients feel anxious about eating in social situations or worry about symptoms occurring at inconvenient times. Connecting with support groups, either in person or online, can provide valuable tips and emotional encouragement from others who understand the challenges. Regular follow-up with healthcare providers ensures that treatments continue working effectively and allows for adjustments when needed. Most importantly, patients should remember that achalasia is a manageable condition, and with proper treatment and self-care strategies, they can continue to enjoy food and maintain good nutrition.

Frequently Asked Questions

Will achalasia get worse over time if left untreated?

Yes, achalasia typically progresses gradually over months to years if not treated. The esophagus may become increasingly dilated and lose more function, making swallowing even more difficult and increasing the risk of complications like aspiration pneumonia.

Can I still eat my favorite foods after achalasia treatment?

Most patients can return to eating a wide variety of foods after successful treatment, though some may need to continue avoiding particularly problematic items like bread or rice. Many people find they can enjoy most of their favorite foods again with proper chewing and eating techniques.

Is achalasia surgery risky?

Modern surgical treatments for achalasia, particularly laparoscopic Heller myotomy and POEM, have low complication rates in experienced hands. Most patients experience significant symptom improvement with minimal risks, and recovery times are typically shorter than with traditional open surgery.

Will I need repeat treatments for achalasia?

This depends on the treatment chosen. Surgical options like Heller myotomy and POEM typically provide long-lasting relief for most patients. Pneumatic dilation may need to be repeated every few years, while medications and botulinum toxin injections require more frequent retreatment.

Can achalasia cause cancer?

Long-term achalasia slightly increases the risk of developing esophageal squamous cell carcinoma, but this complication remains rare. Regular monitoring and successful treatment of achalasia can help minimize this risk.

Is achalasia genetic or hereditary?

Most cases of achalasia occur sporadically without a clear genetic pattern. However, rare familial cases have been reported, and some genetic variations may influence susceptibility to developing the condition.

Can stress make achalasia symptoms worse?

While stress doesn't cause achalasia, it can worsen symptoms in some patients by affecting eating habits and increasing muscle tension. Managing stress through relaxation techniques may help improve overall symptom control.

How long does it take to recover from achalasia surgery?

Recovery varies by procedure, but most patients can return to normal activities within 1-2 weeks after laparoscopic surgery. Full healing and optimal symptom relief may take several weeks to a few months as the esophagus adapts to the changes.

Can children develop achalasia?

Yes, though achalasia is rare in children, it can occur at any age. Pediatric achalasia may be more challenging to diagnose because children might not be able to describe their symptoms clearly, and the condition can be mistaken for feeding problems or reflux.

Will my voice be affected by achalasia or its treatment?

Achalasia itself rarely affects the voice, though some patients may experience hoarseness from regurgitation. Surgical treatments are designed to avoid the nerves that control vocal cord function, so voice changes are uncommon complications.
