Overview

Achalasia is a rare disorder that affects the esophagus, the muscular tube that connects the throat to the stomach. It is characterized by the inability of the lower esophageal sphincter (LES), a ring of muscle at the bottom of the esophagus, to relax and allow food and liquids to pass into the stomach. Symptoms of achalasia typically include difficulty swallowing, regurgitation of undigested food, chest pain, heartburn, and weight loss. These symptoms may worsen over time if left untreated. The exact cause of achalasia is not known, but it is believed to be a result of damage to the nerves in the esophagus that control the muscles involved in swallowing. There may also be a genetic component to the disorder. Achalasia is diagnosed through a variety of tests, including an esophageal manometry to measure the pressure in the esophagus and an endoscopy to examine the inside of the esophagus and stomach. Treatment options include medication, minimally invasive procedures such as balloon dilation or botulinum toxin injection, or surgery to cut the LES muscle. With proper treatment, most people with achalasia can manage their symptoms and lead a normal life. However, some people may experience complications such as aspiration pneumonia, esophageal perforation, or a slightly increased risk of esophageal cancer.

Symptoms

- Difficulty swallowing: This is the most common symptom of achalasia. Patients may feel that food or liquids get stuck in the chest or throat. - Regurgitation of undigested food: This occurs when food and liquids are brought back up into the mouth from the esophagus. - Chest pain: Patients may experience a sensation of pressure or discomfort in the chest, especially after eating. - Heartburn: This is a burning sensation in the chest or throat, caused by stomach acid flowing back into the esophagus. - Weight loss: This can occur if patients are unable to eat enough food due to difficulty swallowing. - Coughing or choking: This may occur if food or liquids get stuck in the throat or esophagus. - Fatigue: Patients may experience fatigue due to the effort required to swallow food and liquids. It is important to note that these symptoms can be indicative of other disorders as well, so it is important to seek medical attention if experiencing any of these symptoms.

Causes

The exact cause of achalasia is not fully understood. However, it is believed to be caused by damage to the nerves in the esophagus that control the muscles involved in swallowing, as well as by degeneration of the muscles themselves. There may also be a genetic component to the disorder. Other potential contributing factors to the development of achalasia include: - Autoimmune disorders: Some research suggests that autoimmune disorders may play a role in the development of achalasia, as the disorder is more common in people with other autoimmune diseases. - Viral infections: Some viruses, such as herpes simplex virus and varicella-zoster virus, have been linked to the development of achalasia. - Environmental factors: Exposure to certain environmental toxins and chemicals may also increase the risk of developing achalasia. It is important to note that while these factors may contribute to the development of achalasia, they are not the sole cause of the disorder. More research is needed to fully understand the underlying causes of achalasia.

When to see a doctor

If you experience difficulty swallowing or any other symptoms of achalasia, it is important to seek medical attention as soon as possible. Early diagnosis and treatment can help prevent complications and improve outcomes. You should see a doctor if you experience any of the following: - Difficulty swallowing or a feeling of food getting stuck in your chest or throat - Regurgitation of undigested food - Chest pain, heartburn or acid reflux - Unintentional weight loss - Coughing or choking while eating or drinking - Persistent or severe fatigue - Recurring pneumonia or respiratory infections If you have been diagnosed with achalasia, it is important to work closely with your doctor to manage the condition and prevent complications. You may need to undergo regular monitoring and screening for complications such as aspiration pneumonia, esophageal perforation, Barrett's esophagus, and esophageal cancer.

Risk factors

While the exact cause of achalasia is unknown, there are several factors that may increase the risk of developing the disorder. These include: - Age: Achalasia is most commonly diagnosed in people between the ages of 25 and 60. - Genetics: There may be a genetic component to achalasia, as the disorder can sometimes run in families. - Autoimmune disorders: People with autoimmune disorders, such as lupus or scleroderma, have a higher risk of developing achalasia. - Environmental factors: Exposure to certain environmental toxins and chemicals may increase the risk of developing achalasia. - Infections: Some viral infections, such as herpes simplex virus and varicella-zoster virus, have been linked to the development of achalasia. - Obesity: Being overweight or obese may increase the risk of developing achalasia. - Gender: Achalasia is slightly more common in women than in men. It's important to note that having one or more of these risk factors does not necessarily mean that a person will develop achalasia. Conversely, some people with achalasia may not have any of these risk factors.
