Achalasia is a rare and chronic disorder that affects the esophagus, the tube responsible for carrying food and liquids from the mouth to the stomach. It primarily affects the lower esophageal sphincter (LES), a muscular ring that opens to allow food into the stomach and closes to prevent stomach acid from flowing back into the esophagus. In individuals with achalasia, the LES fails to relax properly, leading to difficulty in swallowing and other related symptoms.
The most common symptoms of achalasia include:
• Dysphagia: Difficulty swallowing both solids and liquids.
• Regurgitation: The sensation of food or liquid coming back up into the throat.
• Chest pain: Pain or discomfort in the chest, often mistaken for heart-related issues.
• Weight loss: Due to reduced food intake caused by swallowing difficulties.
• Heartburn: Some individuals may experience heartburn, although it is less common in achalasia compared to other esophageal conditions.
The exact cause of achalasia is not fully understood, but it is believed to result from the damage or degeneration of the nerves in the esophagus that control the relaxation of the LES. This nerve damage may be due to an autoimmune response, genetic factors, or certain viral infections. However, the precise cause remains a subject of ongoing research.
There are three main types of achalasia, classified based on the appearance of the esophagus on imaging studies:
• Classic Achalasia: The LES fails to relax properly, and there is a lack of normal esophageal contractions.
• Chagas Disease-Induced Achalasia: Caused by an infection with the parasite Trypanosoma cruzi.
• Type III (Spastic) Achalasia: Characterized by vigorous and spastic contractions in the esophagus, rather than the lack of contractions seen in classic achalasia.
Risk Factors –
Achalasia can affect people of all ages and genders, but some factors may increase the risk of developing the condition, including:
• Age: The risk tends to increase with age, with most cases diagnosed in individuals between 25 and 60 years old.
• Family history: Having a close family member with achalasia may slightly increase the risk.
• Autoimmune disorders: There may be a link between achalasia and certain autoimmune conditions.
Diagnosing achalasia involves a combination of medical history review, physical examination, and specialized tests, including:
• Barium Swallow: X-ray imaging with barium contrast to visualize the esophagus and detect abnormalities.
• Esophageal Manometry: Measures the pressure and coordination of esophageal contractions and LES relaxation.
• Endoscopy: A flexible tube with a camera is inserted into the esophagus to rule out other potential causes of symptoms.
If left untreated, achalasia can lead to several complications, such as:
• Aspiration pneumonia: Inhalation of food or liquids into the lungs, leading to lung infections.
• Esophageal dilation: The esophagus may become stretched and dilated, worsening swallowing difficulties.
• Weight loss and malnutrition: Persistent dysphagia can lead to inadequate caloric intake and malnutrition.
Treatment for achalasia aims to improve swallowing and relieve symptoms. The following options are available:
• Pneumatic Balloon Dilation: A procedure where a balloon is inflated to stretch the LES, allowing easier passage of food.
• Heller Myotomy: A surgical procedure that involves cutting the muscles of the LES to facilitate relaxation.
• Botox Injection: Temporary relief can be achieved by injecting botulinum toxin into the LES to weaken the muscle.
• Medications: Although not curative, certain medications can help to reduce symptoms.
• Laparoscopic Surgery: In severe cases or when other treatments fail, laparoscopic surgery may be necessary.

• Intake of gooseberry
• Intake of resins
• Drinking a glass of water in the early morning
