Achalasia: A Disorder Of The Esophagus: Causes, Symptoms and Treatment
Achalasia is a condition that affects the esophagus, the tube that carries food from the mouth to the stomach. In achalasia, the muscles of the lower esophagus fail to relax properly, causing difficulty in moving food into the stomach. This results in a backup of food and liquid in the esophagus, leading to symptoms like difficulty swallowing and regurgitation.
The exact cause of achalasia is not fully understood, but it is believed to be due to damage to the nerves in the esophagus. This damage disrupts the normal contractions of the esophagus that help push food toward the stomach.
Symptoms of Achalasia: A Disorder Of The Esophagus
Achalasia can lead to symptoms such as difficulty swallowing, regurgitation of food, chest pain, and weight loss. If left untreated, achalasia can result in complications like aspiration pneumonia or malnutrition. Seeking medical attention for proper diagnosis and treatment is crucial for managing achalasia and improving quality of life.
- Difficulty swallowing, especially with solid foods, often leading to regurgitation and a sensation of food getting stuck in the chest.
- Chest pain or discomfort, which can be sharp or dull, and may worsen during eating or drinking.
- Heartburn or acid reflux, due to the impaired function of the lower esophageal sphincter, allowing stomach acid to back up into the esophagus.
- Unintentional weight loss, as the condition can lead to reduced food intake and inadequate nutrient absorption.
- Persistent cough or aspiration pneumonia, caused by food or liquid entering the airways due to the dysfunctional esophageal muscles.

This dysfunction results in difficulty swallowing, regurgitation of food, and chest pain. Additionally, certain viral infections and environmental triggers may play a role in the development of this condition.
- Achalasia can be caused by the degeneration of nerve cells in the esophagus, leading to impaired muscle relaxation and difficulty swallowing.
- In some cases, the exact cause of achalasia remains unknown, but it is believed to involve a combination of genetic and environmental factors.
- Autoimmune reactions targeting the nerves in the esophagus have been linked to the development of achalasia, disrupting the normal functioning of the muscles.
- Viral infections, such as herpes simplex virus or varicella-zoster virus, have been associated with triggering the autoimmune response that contributes to achalasia.
Types Of Achalasia: A Disorder Of The Esophagus
Achalasia, a disorder affecting the esophagus, comes in three main types: Type I, characterized by aperistalsis and incomplete lower esophageal sphincter (LES) relaxation; Type II, with aperistalsis and pan-esophageal pressurization; and Type III, showing spastic contractions in the distal esophagus. Understanding the different types is crucial for accurate diagnosis and appropriate management of achalasia to alleviate symptoms and improve quality of life for affected individuals.
- Classic achalasia: Characterized by impaired relaxation of the lower esophageal sphincter and absent peristalsis in the esophageal body.
- Vigorous achalasia: Shows high-pressure contractions in the esophageal body on manometry.
- Achalasia with esophageal compression: Involves additional compression of the esophagus due to a tortuous or dilated esophagus.
- Achalasia with spastic contractions: Presents with spastic contractions in the esophageal body along with impaired relaxation of the lower esophageal sphincter.
- End-stage achalasia: Represents advanced disease with severely dilated esophagus and minimal esophageal motility.
Risk Factors
While the exact cause of achalasia is unknown, several risk factors have been identified. These include autoimmune conditions, genetic predisposition, viral infections, nerve damage, and possibly environmental factors. Understanding these risk factors is crucial for early detection and management of this condition, which can significantly impact a person's quality of life.
- Genetic predisposition: Family history of achalasia may increase the risk of developing the condition.
- Autoimmune disorders: Certain autoimmune conditions, such as lupus or Sjogren's syndrome, can be associated with achalasia.
- Age: Achalasia is more commonly diagnosed in individuals between 25 and 60 years old.
- Obesity: Being overweight or obese can potentially exacerbate symptoms and complications of achalasia.
- Previous viral infections: Infections like herpes simplex virus may trigger an inflammatory response that contributes to achalasia development.

Diagnosis of Achalasia: A Disorder Of The Esophagus
Typically, the process starts with a detailed medical history and physical examination to assess symptoms like difficulty swallowing.Endoscopy may also be performed to rule out other conditions. By combining these methods, healthcare providers can accurately diagnose achalasia and tailor a suitable treatment plan for the individual.
- Barium swallow: a diagnostic test where the patient swallows a barium solution to visualize the esophagus on X-ray.
- Esophageal manometry: measures pressure and coordination of muscle contractions in the esophagus to assess its function.
Treatment for Achalasia: A Disorder Of The Esophagus
Treatment options for achalasia aim to alleviate symptoms and improve esophageal function. These may include pneumatic dilation, where the sphincter is stretched using a balloon, surgical procedures like Heller myotomy to cut the muscle fibers of the sphincter, and botulinum toxin injections to relax the sphincter temporarily.
Lifestyle modifications, dietary changes, and medications to help with symptoms like reflux can also be part of the treatment plan for individuals with achalasia. Consulting with a healthcare provider is essential to determine the most suitable treatment approach.
Another option is laparoscopic Heller myotomy, a surgery that involves cutting the muscles at the lower esophageal sphincter to reduce its constriction. Botox injections into the lower esophageal sphincter can also be used to temporarily relax the muscle and improve food passage. Oral medications, such as calcium channel blockers or nitrates, may be prescribed to help relax the esophageal muscles and improve swallowing.
