Living With Achalasia

Living with achalasia means managing a rare condition where your esophagus (food pipe) struggles to move food and liquids into your stomach. This happens because the muscle at the bottom of your esophagus doesn't relax properly, and the esophageal muscles don't push food down effectively. While there's no cure, various treatments and lifestyle adjustments can significantly improve symptoms and quality of life.

What is Living With Achalasia?

Living with achalasia involves managing a chronic condition that affects your esophagus, the tube that carries food from your mouth to your stomach. In achalasia, the ring of muscle at the bottom of your esophagus (lower esophageal sphincter or LES) fails to open properly, and the muscles in the esophagus don't contract to push food down. This causes food and liquids to get stuck, leading to discomfort and other symptoms.

Achalasia is a rare disorder that impacts how you swallow and digest food. Normally, when you eat, your esophageal muscles contract in a wave-like motion (called peristalsis) to move food downwards. At the same time, the lower esophageal sphincter (LES), a valve-like muscle, relaxes to let food pass into your stomach. With achalasia, these two crucial actions don't happen correctly. The LES stays tightly closed, and the esophageal muscles lose their ability to push food. Over time, the esophagus can become enlarged and weakened, making it even harder for food to pass through. This condition is chronic, meaning it requires ongoing management to control symptoms and prevent complications.

Symptoms

The main symptom of achalasia is difficulty swallowing (dysphagia), affecting both solid foods and liquids. Other common symptoms include regurgitation of undigested food, chest pain, heartburn, and unintentional weight loss. These symptoms often worsen over time, significantly impacting daily eating and overall quality of life.

Many people with achalasia first notice difficulty swallowing (dysphagia). This feeling can range from food getting stuck in your throat or chest to a complete inability to swallow. You might find yourself needing to drink a lot of water with meals or changing how you eat to help food go down. Another common symptom is regurgitation, where undigested food or liquid comes back up into your mouth, especially after eating or when lying down. This can lead to coughing, choking, or even aspiration, where food accidentally enters your lungs. Some individuals also experience non-cardiac chest pain, which can be severe, or a burning sensation similar to heartburn (pyrosis). Unexplained weight loss is also common due to reduced food intake and difficulty absorbing nutrients. Nighttime coughing and a feeling of fullness after only a few bites are also frequently reported.

Causes & risk factors

The exact cause of achalasia is often unknown, but it's believed to be due to damage to the nerves in the esophagus that control muscle function and the lower esophageal sphincter. While there are no clear lifestyle or genetic risk factors, some theories suggest an autoimmune response or viral infection might play a role in nerve damage. Achalasia can affect anyone, though it's typically diagnosed in middle-aged or older adults.

Achalasia occurs when the nerve cells in the esophagus that coordinate swallowing become damaged or die. These nerves are responsible for telling the lower esophageal sphincter (LES) to relax and for initiating the wave-like muscle contractions (peristalsis) that move food down. When these nerves are damaged, the LES remains constricted, and the esophagus loses its ability to push food. In most cases, the reason for this nerve damage is not clear, and the condition is called idiopathic achalasia. Researchers are exploring potential causes, including autoimmune reactions where the body's immune system mistakenly attacks its own tissues, or certain viral infections that might trigger the nerve damage. Achalasia is not typically inherited, and there are no known dietary or lifestyle factors that increase your risk. While it can occur at any age, it is most commonly diagnosed in people between 30 and 60 years old.

How it's diagnosed

Diagnosing achalasia typically involves a combination of tests to evaluate esophageal function and rule out other conditions. Key diagnostic tools include esophageal manometry, which measures muscle contractions, and a barium swallow (esophagram), an X-ray that shows how liquids move through the esophagus. An upper endoscopy may also be performed to visually inspect the esophagus and stomach.

If you are experiencing symptoms like difficulty swallowing, your doctor will likely recommend specific tests to diagnose achalasia. The most definitive test is esophageal manometry. This procedure involves passing a thin, flexible tube through your nose into your esophagus to measure the pressure and coordination of muscle contractions when you swallow. In achalasia, manometry typically shows a lack of peristalsis and a high-pressure, non-relaxing lower esophageal sphincter (LES). Another important test is a barium swallow, also known as an esophagram. During this X-ray procedure, you drink a liquid containing barium, which coats the inside of your esophagus, making it visible on X-ray images. This test can show if the esophagus is dilated (enlarged) and if there's a characteristic narrowing at the LES, often described as a 'bird's beak' appearance. An upper endoscopy may also be performed, where a thin, lighted tube with a camera is inserted down your throat to visually examine the lining of your esophagus, stomach, and the beginning of your small intestine. This helps rule out other conditions that can cause similar symptoms, such as tumors or strictures (narrowing).

Treatment options

Treatment for achalasia focuses on relaxing or opening the lower esophageal sphincter (LES) to allow food to pass into the stomach, as there is no cure for the underlying nerve damage. Options range from medications and endoscopic procedures like pneumatic dilation or Botox injections to surgical interventions such as Heller myotomy or peroral endoscopic myotomy (POEM). Your doctor will discuss the best approach based on your specific condition and overall health.

The goal of achalasia treatment is to relieve symptoms by reducing the pressure in the lower esophageal sphincter (LES). Medications, such as nitrates or calcium channel blockers, can sometimes offer temporary relief by relaxing the LES, but they are generally not effective for long-term management due to side effects and diminishing effectiveness. These are usually considered for people who cannot undergo other procedures. Endoscopic procedures are common. Pneumatic dilation involves inserting a balloon into the LES and inflating it to stretch and widen the muscle. This procedure often needs to be repeated over time. Another endoscopic option is Botox (botulinum toxin) injection directly into the LES, which temporarily paralyzes the muscle, allowing it to relax. Botox provides relief for several months but also requires repeat injections. For more lasting relief, surgical options are often recommended. A laparoscopic Heller myotomy is a surgical procedure where the muscle fibers of the LES are carefully cut. This is often combined with a partial fundoplication, a procedure that wraps part of the stomach around the esophagus, to prevent acid reflux. A newer, minimally invasive endoscopic procedure called peroral endoscopic myotomy (POEM) involves cutting the LES muscle from inside the esophagus using an endoscope, offering a similar outcome to Heller myotomy without external incisions. Your healthcare provider will help you weigh the benefits and risks of each treatment.

Recovery & outlook

Achalasia is a chronic condition, but with proper treatment, most people experience significant improvement in their symptoms and quality of life. Recovery involves managing the condition long-term through regular follow-ups and lifestyle adjustments. While treatments can alleviate swallowing difficulties, they do not cure the underlying nerve damage, so ongoing care is essential to monitor for complications and maintain symptom control.

After treatment for achalasia, many individuals find that their difficulty swallowing and other symptoms improve considerably. However, it's important to remember that achalasia is a chronic condition, and treatments aim to manage symptoms rather than cure the underlying problem. You may still need to make certain lifestyle adjustments, such as eating slowly, taking small bites, chewing food thoroughly, and drinking water during meals to help food pass. Regular follow-up appointments with your doctor are crucial to monitor your condition and ensure the treatment remains effective. Sometimes, symptoms can return, requiring further intervention. There is also a slightly increased risk of developing esophageal cancer in people with long-standing achalasia, so your doctor may recommend periodic endoscopic surveillance to screen for any changes. By adhering to your treatment plan and making necessary lifestyle changes, you can effectively manage achalasia and maintain a good quality of life.

When to see a doctor

You should see your doctor if you experience persistent difficulty swallowing, unexplained weight loss, or frequent regurgitation of food. Seek immediate medical attention if you have severe chest pain, are unable to swallow anything at all, or experience choking episodes that make it hard to breathe. These could be signs of a serious complication or an emergency requiring prompt evaluation.

It is important to contact your healthcare provider if you notice new or worsening symptoms related to your achalasia. This includes if your difficulty swallowing (dysphagia) becomes more severe, if you start losing weight without trying, or if you experience more frequent or painful regurgitation. These changes might indicate that your current treatment needs adjustment or that a complication is developing. Seek emergency medical care immediately if you experience any of the following: sudden, severe chest pain that is not relieved by usual methods; a complete inability to swallow any liquids or solids; or severe choking episodes accompanied by difficulty breathing. These could be signs of a medical emergency, such as food impaction or aspiration pneumonia, which require urgent attention to prevent serious health risks.

Frequently asked questions

Can achalasia be cured?

No, achalasia cannot be cured because the nerve damage in the esophagus is permanent. However, various treatments are highly effective at managing symptoms by relaxing or opening the lower esophageal sphincter, significantly improving swallowing and quality of life.

What dietary changes can help with achalasia?

While there's no specific achalasia diet, many people find relief by eating smaller, more frequent meals, chewing food thoroughly, taking small bites, and drinking plenty of water during meals. Avoiding very hot or cold foods, carbonated beverages, and tough meats may also help. Elevating your head during sleep can reduce nighttime regurgitation.

Is achalasia a serious condition?

Yes, achalasia is a serious chronic condition that can lead to significant weight loss, malnutrition, and aspiration pneumonia if left untreated. While not immediately life-threatening, it requires ongoing medical management to prevent complications and maintain a good quality of life.

How often do I need follow-up appointments after treatment?

The frequency of follow-up appointments depends on your specific treatment, how well your symptoms are controlled, and your doctor's recommendations. Initially, you might have more frequent visits, then typically annual check-ups. Regular monitoring is important to assess treatment effectiveness and screen for potential complications.

Can achalasia lead to cancer?

People with long-standing achalasia have a slightly increased risk of developing esophageal cancer compared to the general population. For this reason, your doctor may recommend periodic endoscopic surveillance (visual inspection of the esophagus) to monitor for any precancerous changes or early signs of cancer.

What is the difference between achalasia and GERD (acid reflux)?

Achalasia involves the lower esophageal sphincter (LES) failing to relax, preventing food from entering the stomach, and the esophagus losing its ability to push food down. GERD, or acid reflux, typically involves the LES relaxing too much or at inappropriate times, allowing stomach acid to flow back up into the esophagus. While both can cause chest pain and heartburn, their underlying mechanisms and treatments differ significantly.
