Achalasia: Trouble Swallowing, Esophageal Testing, and Treatment Choices

Achalasia is a rare swallowing disorder in which the esophagus has trouble pushing food into the stomach and the lower esophageal sphincter does not relax normally. With the right testing and treatment, many people can improve swallowing, reduce discomfort, and protect nutrition.

Overview

Achalasia is a condition that affects the esophagus, the muscular tube that carries food and liquids from the mouth to the stomach. In achalasia, two problems happen together: the muscles of the esophagus do not squeeze in a coordinated way, and the lower esophageal sphincter, the valve at the entrance to the stomach, does not relax properly during swallowing.

Because of this, swallowed food and drink can remain in the esophagus instead of passing smoothly into the stomach. Over time, the esophagus may stretch and become less effective. Symptoms often develop gradually, so some people adapt their eating habits for months or years before seeking help.

Achalasia is not the same as occasional heartburn or simple indigestion. It is a specific swallowing disorder that usually requires medical evaluation. Although it is uncommon, it is treatable, and many people feel better once the cause of their swallowing difficulty is identified.

Symptoms

The most common symptom of achalasia is trouble swallowing, known medically as dysphagia. Many people notice that both solids and liquids can be difficult to swallow, which helps distinguish achalasia from some other esophageal problems. Swallowing may feel slow, uncomfortable, or as if food is getting stuck in the chest.

Another frequent symptom is regurgitation, when undigested food or saliva comes back up into the mouth, especially after meals or when lying down. Some people also have chest discomfort, a feeling of fullness behind the breastbone, coughing at night, bad breath, or unintended weight loss. Repeated regurgitation can sometimes lead to aspiration, meaning food or liquid enters the airways.

Symptoms can vary from person to person and may become more noticeable over time. A person should not assume that persistent swallowing difficulty is only due to stress or reflux. If symptoms continue, a medical assessment is important to find the cause and guide the right treatment.

• Difficulty swallowing solids and liquids
• Food sticking in the chest
• Regurgitation of undigested food or saliva
• Chest pain or pressure after eating
• Weight loss or reduced appetite
• Nighttime cough or choking episodes

Causes and Risk Factors

Achalasia happens when nerves in the esophagus are damaged or lost, especially those that help control esophageal movement and relaxation of the lower esophageal sphincter. The exact reason this nerve damage occurs is often not clear. Experts believe the process may involve autoimmune, inflammatory, or sometimes viral-related mechanisms in susceptible individuals.

Most cases are considered primary achalasia, meaning there is no single clearly identified cause. A much less common situation is secondary, or pseudoachalasia, where another condition mimics achalasia. In some adults, this may happen because of a tumor near the junction of the esophagus and stomach, which is one reason careful testing is important.

Achalasia can occur at different ages but is often diagnosed in adulthood. It does not appear to be caused by spicy foods, anxiety, or ordinary acid reflux alone. However, because symptoms can overlap with reflux or other swallowing problems, achalasia may at first be mistaken for gastroesophageal reflux disease.

How Achalasia Is Diagnosed

Diagnosis usually begins with a review of symptoms, eating difficulties, weight changes, and any episodes of regurgitation or chest pain. A doctor may ask whether swallowing problems affect solids, liquids, or both, and whether symptoms are getting worse. This history helps narrow down the possible causes of dysphagia.

Upper endoscopy is commonly used to look inside the esophagus and stomach and to rule out other conditions such as narrowing, inflammation, or a mass. During this test, a thin flexible tube with a camera is passed through the mouth. Endoscopy may show retained food or saliva in the esophagus and resistance at the lower sphincter, but further tests are usually needed to confirm achalasia.

A barium swallow, also called an esophagram, is another important test. The patient swallows a contrast liquid while X-ray images are taken. In achalasia, the esophagus may appear enlarged, with a narrowed lower end sometimes described as a bird-beak shape. The most specific test is esophageal manometry, which measures pressure and muscle activity in the esophagus and confirms how the lower sphincter behaves during swallowing.

These tests also help classify the type of achalasia, which can influence treatment planning. In some cases, doctors may also evaluate for related issues such as malnutrition, aspiration risk, or conditions that can resemble achalasia.

Treatment Options

Treatment for achalasia does not restore normal nerve function, but it can significantly improve swallowing by reducing the tightness of the lower esophageal sphincter. The best option depends on the person’s age, general health, achalasia subtype, anatomy, and personal preferences. A gastroenterologist and surgeon often work together to choose the most suitable approach.

One well-established treatment is pneumatic dilation, an endoscopic procedure in which a balloon is used to stretch the lower sphincter. Another effective option is peroral endoscopic myotomy (POEM), which uses an endoscope to cut the tight muscle from inside the esophagus. Surgical treatment may include esophageal surgery such as Heller myotomy, often combined with an anti-reflux procedure to help reduce acid-related symptoms afterward.

Some patients may receive botulinum toxin injection into the lower sphincter, especially if they are not good candidates for more durable procedures. Medications can sometimes provide short-term symptom relief, but they are generally less effective than procedural treatments. When symptoms overlap with reflux or return after treatment, doctors may also evaluate for gastroenterology care and follow-up testing.

Every option has benefits and limitations, including the possibility of recurrence or post-treatment reflux. For this reason, treatment planning should be individualized, and follow-up remains an important part of long-term care.

Living With Achalasia and Self-care

Daily habits can help some people manage symptoms, especially before treatment or during recovery. Eating slowly, chewing thoroughly, taking small bites, and drinking water with meals may make swallowing easier. Many people find that remaining upright during and after meals helps food move downward more effectively.

It may also help to avoid eating very close to bedtime and to raise the head of the bed if nighttime regurgitation occurs. Keeping track of foods that seem harder to swallow can be useful, though no special diet cures achalasia. If weight loss or dehydration becomes a concern, a doctor or dietitian may recommend a softer, higher-calorie eating plan until treatment is completed.

Self-care is supportive, but it is not a substitute for medical treatment when symptoms are persistent. If swallowing difficulty is ongoing, worsening, or associated with coughing or choking, the condition should be assessed by a qualified specialist.

When to See a Doctor

A person should seek medical advice if swallowing becomes difficult, painful, or progressively worse. Trouble swallowing both solids and liquids, repeated regurgitation, unexplained weight loss, or chest discomfort after eating all deserve evaluation. These symptoms do not always mean achalasia, but they should not be ignored.

Urgent medical attention is important if someone cannot keep liquids down, has signs of dehydration, develops fever after choking episodes, or has breathing symptoms that may suggest aspiration. Because several different conditions can affect swallowing, proper diagnosis is the safest way to begin treatment.

Near the end of the care pathway, some patients may benefit from centers that offer coordinated gastroenterology, endoscopy, radiology, and surgical expertise. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat achalasia for international patients when advanced evaluation and treatment are needed.

Frequently asked questions

Is achalasia the same as acid reflux?

No. Achalasia is a swallowing disorder caused by poor esophageal movement and failure of the lower esophageal sphincter to relax properly. Acid reflux can sometimes occur along with achalasia or after treatment, but the two conditions are different.

Can achalasia go away on its own?

Achalasia usually does not go away without treatment. Symptoms often progress gradually over time. Medical evaluation is important because effective treatments can improve swallowing and quality of life.

What is the best test for achalasia?

Esophageal manometry is generally considered the key test for confirming achalasia. It measures pressure and muscle coordination in the esophagus and lower sphincter. Doctors often use it together with endoscopy and a barium swallow to make a complete diagnosis.

Is achalasia cancer?

No, achalasia itself is not cancer. However, some cancers can mimic achalasia, especially in older adults or when symptoms begin quickly, which is why testing is important. A doctor may use endoscopy and imaging to rule out other causes.

Will I need surgery for achalasia?

Not everyone needs surgery, but many people benefit from a procedure that helps the lower esophageal sphincter open more easily. Options may include pneumatic dilation, endoscopic myotomy, or surgical myotomy. The best choice depends on individual factors and specialist assessment.

Can achalasia come back after treatment?

Symptoms can return or change over time, even after successful treatment. Some people need repeat treatment or ongoing monitoring. Regular follow-up helps doctors identify recurrence, reflux, or other issues early.
