Achalasia Cardia

Achalasia cardia is a rare disorder that makes swallowing increasingly difficult and uncomfortable. The condition affects the esophagus, the muscular tube that carries food from your mouth to your stomach, causing it to lose its ability to push food downward effectively. At the same time, the valve at the bottom of the esophagus fails to relax properly, creating a bottleneck that prevents food and liquids from entering the stomach normally.

Symptoms

Common signs and symptoms of Achalasia Cardia include:

Difficulty swallowing both solids and liquids
Food getting stuck in the chest
Chest pain, especially after eating
Regurgitation of undigested food
Heartburn or acid reflux symptoms
Unintentional weight loss
Coughing or choking while eating
Bad breath from food remaining in esophagus
Chest pressure or fullness
Difficulty burping or belching
Nighttime coughing from food regurgitation
Voice changes or hoarseness

When to see a doctor

If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.

Causes & Risk Factors

Several factors can contribute to Achalasia Cardia.

Achalasia occurs when the nerve cells that control esophageal muscle contractions are damaged or destroyed.

Achalasia occurs when the nerve cells that control esophageal muscle contractions are damaged or destroyed. These nerves, part of what doctors call the enteric nervous system, normally coordinate the wave-like contractions that push food toward the stomach. When they malfunction, the esophagus loses its ability to propel food effectively, and the lower esophageal sphincter fails to relax when swallowing.

The exact reason why these nerve cells become damaged remains largely unknown in most cases.

The exact reason why these nerve cells become damaged remains largely unknown in most cases. Some researchers believe it may result from an autoimmune reaction, where the body's immune system mistakenly attacks its own nerve tissue. Viral infections have also been suggested as possible triggers, though no specific virus has been definitively linked to the condition. In rare cases, achalasia can be secondary to other diseases like cancer or Chagas disease, which is caused by a parasitic infection.

Genetic factors may play a role in some families, though achalasia is rarely inherited directly.

Genetic factors may play a role in some families, though achalasia is rarely inherited directly. Most cases appear to be sporadic, meaning they occur randomly without a clear family history. The nerve damage typically develops slowly over time, which explains why symptoms usually worsen gradually rather than appearing suddenly.

Risk Factors

  • Age between 25-60 years
  • Family history of achalasia
  • Autoimmune disorders
  • Previous viral infections affecting the esophagus
  • Chagas disease infection
  • Genetic mutations affecting nerve function
  • Living in areas where Chagas disease is common
  • Previous chest radiation therapy
  • Certain medications that affect nerve function

Diagnosis

How healthcare professionals diagnose Achalasia Cardia:

  • 1

    Diagnosing achalasia typically begins with a thorough medical history and physical examination.

    Diagnosing achalasia typically begins with a thorough medical history and physical examination. Your doctor will ask detailed questions about your swallowing difficulties, when they started, and how they've progressed over time. They'll want to know if you have trouble with both solids and liquids, which is a key clue that distinguishes achalasia from other swallowing disorders that usually affect solids first.

  • 2

    The most definitive test for achalasia is esophageal manometry, which measures the pressure and coordination of muscle contractions in your esophagus.

    The most definitive test for achalasia is esophageal manometry, which measures the pressure and coordination of muscle contractions in your esophagus. During this test, a thin, flexible tube is passed through your nose and down into your esophagus while you swallow small amounts of water. A barium swallow study, where you drink a chalky liquid and have X-rays taken, can show the characteristic "bird's beak" appearance of the esophagus that's typical in achalasia. An upper endoscopy may also be performed to rule out other conditions and examine the esophageal lining directly.

    Additional tests might include a chest CT scan to check for other abnormalities and blood tests to rule out underlying conditions.

    Additional tests might include a chest CT scan to check for other abnormalities and blood tests to rule out underlying conditions. Your doctor may also want to exclude gastroesophageal reflux disease (GERD), esophageal cancer, or other motility disorders that can cause similar symptoms. The combination of characteristic symptoms, manometry findings, and imaging results usually provides a clear diagnosis.

Complications

  • The most serious complication of untreated achalasia is aspiration pneumonia, which occurs when food or liquids regurgitate and enter the lungs instead of going down the esophagus properly.
  • This can lead to serious lung infections and breathing difficulties, particularly during sleep when regurgitation is more likely to happen.
  • The risk increases as the condition progresses and the esophagus becomes more dilated and dysfunctional.
  • Other complications include significant weight loss and malnutrition due to the inability to eat adequate amounts of food.
  • The esophagus may also become severely enlarged over time, a condition called megaesophagus, which can make treatment more challenging.
  • Some patients develop esophagitis from food remaining in the esophagus for extended periods, and there's a small but increased risk of esophageal cancer in people with long-standing, untreated achalasia.
  • With proper treatment, most of these complications can be prevented or effectively managed.

Prevention

  • Since the exact cause of achalasia remains unknown in most cases, there are no proven strategies to prevent the condition from developing.
  • Unlike some digestive disorders that can be prevented through lifestyle changes, achalasia appears to result from nerve damage that occurs for reasons beyond our current control.
  • The sporadic nature of most cases means that even people with no risk factors can develop the condition.
  • However, if you live in or travel to areas where Chagas disease is endemic, protecting yourself from the insects that carry this parasitic infection can prevent the secondary form of achalasia associated with this disease.
  • This includes using insect repellent, sleeping under bed nets, and avoiding sleeping in adobe or thatch-roofed buildings where the insects commonly nest.
  • The most practical approach is early recognition and treatment of symptoms.
  • If you experience persistent difficulty swallowing, especially if it affects both solids and liquids, seek medical evaluation promptly.
  • Early diagnosis and treatment can prevent complications and help maintain better esophageal function over time.
  • Regular follow-up care after treatment is also essential for monitoring the condition and addressing any recurring symptoms quickly.

Treatment for achalasia focuses on reducing the pressure at the lower esophageal sphincter to allow food to pass more easily into the stomach.

Treatment for achalasia focuses on reducing the pressure at the lower esophageal sphincter to allow food to pass more easily into the stomach. The most effective approaches are procedures that physically disrupt or weaken this tight muscle. Pneumatic dilation involves inserting a balloon into the esophagus and inflating it to stretch and partially tear the muscle fibers. This outpatient procedure provides good relief for many patients, though it may need to be repeated over time.

Laparoscopic Heller myotomy is a minimally invasive surgical option that involves cutting the muscle fibers of the lower esophageal sphincter.

Laparoscopic Heller myotomy is a minimally invasive surgical option that involves cutting the muscle fibers of the lower esophageal sphincter. This procedure often provides longer-lasting results than pneumatic dilation and is frequently combined with an anti-reflux procedure to prevent acid reflux afterward. A newer option called POEM (Peroral Endoscopic Myotomy) allows surgeons to cut the muscle through an endoscope inserted through the mouth, avoiding external incisions entirely.

Surgical

Medications can help some patients, particularly those who aren't candidates for procedures.

Medications can help some patients, particularly those who aren't candidates for procedures. Calcium channel blockers like nifedipine and nitrates can help relax the esophageal muscles, though their effects are usually modest. Botulinum toxin injections into the lower esophageal sphincter can provide temporary relief by paralyzing the muscle, but the effects typically wear off after three to six months.

Medication

Dietary modifications can also improve symptoms significantly.

Dietary modifications can also improve symptoms significantly. Eating smaller, more frequent meals and chewing food thoroughly helps reduce the workload on the damaged esophagus. Drinking plenty of water with meals and avoiding very hot or very cold foods can make swallowing easier. Some patients find that sleeping with their head elevated helps prevent nighttime regurgitation.

Lifestyle

Living With Achalasia Cardia

Living successfully with achalasia often involves adapting your eating habits and meal planning. Many people find that eating slowly and chewing food thoroughly makes a significant difference in their comfort level. Taking small bites, drinking plenty of water with meals, and allowing extra time for eating can help prevent food from getting stuck. Some patients discover that certain food textures work better than others, and keeping a food diary can help identify which foods cause the most trouble.

Emotional support is equally important, as dealing with a chronic swallowing disorder can affect social activities and cause anxiety around mealtimes.Emotional support is equally important, as dealing with a chronic swallowing disorder can affect social activities and cause anxiety around mealtimes. Many patients benefit from connecting with support groups or online communities where they can share experiences and coping strategies with others who understand the challenges. Working with a nutritionist can help ensure you're getting adequate nutrition despite eating difficulties.
Regular follow-up care with your gastroenterologist is essential for monitoring your condition and adjusting treatment as needed.Regular follow-up care with your gastroenterologist is essential for monitoring your condition and adjusting treatment as needed. Most people with achalasia can maintain active, fulfilling lives with proper management. The key is working closely with your healthcare team to find the right combination of treatments and lifestyle modifications that work best for your specific situation. Many patients report significant improvement in their quality of life once they find an effective treatment approach.

Frequently Asked Questions

Can achalasia be cured completely?
While there's no cure that restores normal esophageal function, treatments can effectively manage symptoms and allow most people to eat normally. The goal is to reduce the obstruction at the bottom of the esophagus so food can pass through more easily.
Will I need to follow a special diet forever?
Most people can return to a relatively normal diet after successful treatment, though some may need to avoid certain foods or eat more slowly. Your doctor or a nutritionist can help you develop an eating plan that works for your situation.
How often do treatments need to be repeated?
This varies by treatment type and individual response. Pneumatic dilation may need repeating every few years, while surgical procedures often provide longer-lasting results. Regular follow-up helps determine when additional treatment might be needed.
Can I still exercise and be active with achalasia?
Yes, most people with achalasia can maintain normal activity levels. You may need to time your exercise around meals and stay hydrated, but physical activity is generally encouraged and beneficial for overall health.
Is achalasia hereditary?
While rare familial cases have been reported, the vast majority of achalasia cases are sporadic and not inherited. Having achalasia doesn't significantly increase the risk for your children or other family members.
What's the difference between achalasia and GERD?
Achalasia involves difficulty swallowing due to poor esophageal muscle function, while GERD is caused by stomach acid backing up into the esophagus. However, some symptoms can overlap, which is why proper testing is important for accurate diagnosis.
Can stress make achalasia symptoms worse?
While stress doesn't cause achalasia, it can potentially worsen symptoms by affecting how you eat and digest food. Managing stress through relaxation techniques and proper meal planning often helps improve overall comfort.
Are there any foods I should completely avoid?
This varies by individual, but many people find that very hot or cold foods, carbonated beverages, and foods that are difficult to chew can be more problematic. Working with your healthcare team can help identify your personal trigger foods.
How long does recovery take after treatment?
Recovery time varies by treatment type. After pneumatic dilation, many people feel improvement within days to weeks. Surgical procedures may require a few weeks of modified diet before returning to normal eating patterns.
Can children develop achalasia?
While uncommon, achalasia can occur in children and adolescents. Pediatric cases are often more challenging to diagnose because children may not clearly describe their swallowing difficulties, but treatment approaches are similar to those used in adults.
