Achalasia Complications

Achalasia complications are additional health problems that can arise from achalasia, a rare swallowing disorder where the esophagus struggles to move food into the stomach. These complications can range from nutritional deficiencies to more serious issues like lung infections or, rarely, esophageal cancer. Managing achalasia effectively helps reduce the risk of these problems.

What is Achalasia Complications?

Achalasia complications are health issues that can develop because of achalasia, a condition where the tube connecting your mouth to your stomach (esophagus) doesn't work correctly. The main problem is that the muscle at the bottom of the esophagus (lower esophageal sphincter) doesn't relax, making it hard for food and liquids to pass through, which can lead to various secondary problems.

Achalasia is a rare disorder that affects the esophagus, the muscular tube that carries food from your throat to your stomach. In people with achalasia, the nerves in the esophagus become damaged, causing it to lose its ability to push food down. Additionally, the ring of muscle at the bottom of the esophagus, called the lower esophageal sphincter (LES), fails to open properly during swallowing. This malfunction means food and liquids can get stuck in the esophagus, leading to a backup. Over time, this can cause the esophagus to stretch and enlarge significantly, a condition known as megaesophagus. The constant presence of food and liquid in the esophagus, along with the difficulty in swallowing, sets the stage for various complications.

Symptoms

Symptoms of achalasia complications often include a worsening of existing swallowing difficulties, significant weight loss, or new signs like coughing after eating, fever, or severe chest pain. These symptoms indicate that the underlying achalasia is causing further problems, such as food entering the lungs or irritation of the esophageal lining.

Many complications of achalasia can worsen the symptoms you already experience from the condition itself. For instance, you might notice your difficulty swallowing (dysphagia) becomes more severe or happens more often. You may also experience more frequent regurgitation, where undigested food and saliva come back up into your throat or mouth. One serious complication is aspiration pneumonia, a lung infection caused by food or liquid accidentally entering the lungs instead of the stomach. Symptoms of aspiration pneumonia can include coughing, fever, shortness of breath, and chest pain. If you experience significant, unexplained weight loss, it could be a sign of malnutrition, another common complication due to the ongoing difficulty in eating enough food. Persistent chest pain that is not related to heartburn can also be a symptom of complications, especially if the esophagus is severely enlarged or irritated. It is important to pay attention to any new or worsening symptoms and discuss them with your doctor.

Causes & risk factors

The primary cause of achalasia complications is the long-standing presence of achalasia itself, which leads to food and liquid buildup in the esophagus. Factors like the duration of the disease, the severity of esophageal enlargement, and the specific treatments received can influence the risk of developing these secondary health issues.

Achalasia complications stem directly from the underlying problem of achalasia. When the esophagus cannot properly move food and the lower esophageal sphincter (LES) does not relax, food and liquid accumulate. This accumulation can lead to several issues over time. One significant risk factor for certain complications, particularly esophageal cancer, is the long duration of achalasia. The constant irritation and inflammation of the esophageal lining from retained food and liquid are thought to contribute to cellular changes that can increase cancer risk. While the overall risk of esophageal cancer in people with achalasia is low, it is higher than in the general population, especially for squamous cell carcinoma. Another risk factor for complications like perforation (a hole in the esophagus) is related to the treatments for achalasia. Procedures such as pneumatic dilation, which stretches the LES with a balloon, or surgical myotomy, which cuts the muscle, carry a small risk of causing a tear in the esophageal wall. Gastroesophageal reflux disease (GERD) or Barrett's esophagus can also develop after some achalasia treatments, as these procedures can sometimes weaken the LES too much, allowing stomach acid to flow back into the esophagus.

How it's diagnosed

Achalasia complications are often diagnosed during routine follow-up for achalasia or when new, concerning symptoms arise. Doctors use tests like endoscopy to visually inspect the esophagus, barium swallow to see how liquids move, and manometry to measure muscle contractions, helping to identify the extent of damage or specific complications.

Diagnosing achalasia complications typically involves a combination of tests that are also used to diagnose achalasia itself. If you have achalasia, your doctor will likely recommend regular check-ups to monitor your condition and screen for potential complications. An upper endoscopy involves inserting a thin, flexible tube with a camera down your throat to visually examine the lining of your esophagus, stomach, and the beginning of your small intestine. This can help identify inflammation, irritation, or suspicious areas that might indicate cancer. A barium swallow, also known as an esophagram, involves drinking a liquid containing barium, which coats the inside of your esophagus and shows up on X-rays. This test can reveal how well food moves through your esophagus, if it's enlarged (megaesophagus), or if there are any blockages. Esophageal manometry measures the muscle contractions in your esophagus and the pressure of the lower esophageal sphincter (LES). While primarily used to diagnose achalasia, it can also help assess the severity of esophageal dysfunction and guide treatment decisions, indirectly helping to manage complication risks. If cancer is suspected, a biopsy (taking a small tissue sample for examination) will be performed during an endoscopy.

Treatment options

Treatment for achalasia complications focuses on managing the underlying achalasia to prevent further issues and addressing specific complications as they arise. This can involve procedures to relax the esophageal muscle, nutritional support for weight loss, antibiotics for infections, or, in rare cases, surgery for cancer or perforations.

The primary goal of treating achalasia complications is to effectively manage the achalasia itself. Treatments aim to relax or open the lower esophageal sphincter (LES) so food can pass into the stomach more easily. Common procedures include pneumatic dilation, where a balloon is inflated in the LES to stretch it, and surgical myotomy (Heller myotomy or peroral endoscopic myotomy, POEM), which involves cutting the muscle fibers of the LES. If you develop aspiration pneumonia, treatment will involve antibiotics to clear the infection. For malnutrition and significant weight loss, a healthcare team including a dietitian can provide nutritional counseling and support, sometimes recommending liquid diets or specific supplements. In cases of esophageal perforation, emergency surgery is usually required to repair the hole and prevent severe infection. For the rare complication of esophageal cancer, treatment options depend on the stage and type of cancer but may include surgery, chemotherapy, radiation therapy, or a combination of these. Regular follow-up with your doctor is crucial to monitor for complications and adjust treatment as needed, helping to improve your long-term health and quality of life.

Recovery & outlook

Recovery from achalasia complications varies greatly depending on the specific complication and its severity. While achalasia is a chronic condition requiring lifelong management, effective treatment of complications can significantly improve a person's outlook. Regular monitoring is essential due to the ongoing risk of issues like esophageal cancer.

Achalasia is a chronic condition, meaning it requires ongoing management throughout your life. The recovery and outlook after experiencing complications depend heavily on the type and severity of the complication. For instance, aspiration pneumonia can often be treated successfully with antibiotics, leading to a full recovery from the infection itself, though the underlying risk from achalasia remains. For more serious complications like esophageal cancer, the outlook depends on how early it is detected and the effectiveness of treatment. Early detection through regular screening is vital for improving outcomes. Even after successful treatment of achalasia, such as with myotomy or pneumatic dilation, there is still a need for regular follow-up appointments. These appointments help monitor the effectiveness of the treatment and screen for any new or recurring complications, including the low but increased risk of esophageal cancer. Living with achalasia and its potential complications means working closely with your healthcare team. Adhering to treatment plans, making dietary adjustments, and attending all recommended follow-up appointments are key steps in managing the condition and maintaining the best possible quality of life.

When to see a doctor

You should see a doctor if you experience any new or worsening symptoms related to your achalasia, as these could signal a complication. Specifically, seek medical attention for severe chest pain, coughing after eating, unexplained fever, significant weight loss, or any difficulty breathing, as these may indicate serious issues like aspiration or perforation.

It is important to contact your doctor if you notice any changes in your symptoms or develop new ones. If your difficulty swallowing (dysphagia) becomes much worse, or if you start experiencing severe chest pain that is not relieved by typical heartburn remedies, you should seek medical advice. These could be signs of an enlarged esophagus (megaesophagus) or other serious issues. Immediate medical attention is necessary if you experience symptoms that suggest aspiration pneumonia, such as a new cough, fever, chills, or shortness of breath, especially after eating or drinking. Similarly, if you have sudden, severe chest pain, particularly after an achalasia procedure, it could indicate a rare but serious complication like esophageal perforation (a tear in the esophagus). Unexplained and significant weight loss should also prompt a visit to your doctor, as it can be a sign of malnutrition or other underlying problems. Regular check-ups are essential for people with achalasia to monitor for complications and ensure timely intervention.

Frequently asked questions

Can achalasia lead to cancer?

Yes, people with achalasia have a slightly increased risk of developing esophageal cancer, particularly squamous cell carcinoma, compared to the general population. This risk is still low overall, but it's why regular monitoring and follow-up with your doctor are important.

What is aspiration pneumonia and how does it relate to achalasia?

Aspiration pneumonia is a lung infection that happens when food, liquid, or saliva accidentally enters the lungs instead of going down the esophagus. In achalasia, food and liquid can get stuck in the esophagus and then spill into the windpipe, leading to this type of pneumonia.

Why do people with achalasia lose weight?

People with achalasia often lose weight because it's very difficult and painful to swallow food and liquids. This makes it hard to eat enough calories and nutrients, leading to malnutrition and unintentional weight loss over time.

What is a megaesophagus?

A megaesophagus is an enlarged and stretched esophagus. This happens in achalasia because food and liquid get stuck and accumulate in the esophagus, causing its walls to expand and lose their normal shape and function over many years.

Can achalasia treatments cause new problems?

Yes, while achalasia treatments aim to improve swallowing, some procedures carry risks. For example, pneumatic dilation or surgery can rarely cause a perforation (a hole) in the esophagus. Some treatments might also lead to gastroesophageal reflux disease (GERD) if the lower esophageal sphincter becomes too relaxed.

How often should I be checked for complications if I have achalasia?

The frequency of check-ups depends on your individual condition and your doctor's recommendations. However, regular follow-up appointments, often including endoscopy, are typically advised for people with achalasia to monitor the condition and screen for potential complications like esophageal cancer.
