Key Complaints to Monitor in Patients with Achalasia History

Dysphagia is the most important complaint to monitor in patients with a history of achalasia, followed by weight loss and respiratory symptoms including chest infections. 1, 2

Primary Complaints to Monitor

1. Dysphagia (Answer B)

  • Most characteristic and persistent symptom in achalasia patients
  • Can occur with both solids and liquids (unlike mechanical obstruction which typically affects solids first)
  • May worsen over time, especially if treatment was incomplete
  • Patients may develop compensatory behaviors (eating slowly, drinking excessive fluids)
  • Can signal disease recurrence after treatment 2, 3

2. Weight Loss (Answer C)

  • Results from reduced caloric intake due to dysphagia
  • May indicate disease progression or recurrence
  • Significant weight loss warrants urgent evaluation
  • Can be a sign of complications or inadequate treatment 1, 3

3. Respiratory Symptoms

  • Regurgitation of undigested food, especially when lying down
  • Nocturnal cough or aspiration
  • Recurrent chest infections (Answer A) due to aspiration pneumonia
  • Chronic cough that doesn't respond to typical treatments 1, 2

Additional Important Complaints

4. Regurgitation

  • Undigested food returning to mouth
  • Often occurs hours after eating
  • Can be mistaken for vomiting but lacks nausea and retching
  • Particularly problematic at night when lying down 2, 3

5. Chest Pain

  • Can mimic cardiac pain
  • May occur during or after meals
  • Often related to food impaction or esophageal spasm
  • More common in Type III (spastic) achalasia 2, 3, 4

6. Heartburn-like Symptoms

  • Can be misleading and result in misdiagnosis as GERD
  • May actually represent food fermentation in the esophagus
  • Post-treatment, may indicate true reflux (especially after POEM procedure) 1, 2

Monitoring Based on Achalasia Subtype

Different achalasia subtypes may present with varying symptom patterns:

  • Type I (Classic): More likely to have advanced disease with significant esophageal dilation, regurgitation, and weight loss 2
  • Type II: Often presents with pressurization symptoms and chest discomfort 2
  • Type III (Spastic): More likely to have chest pain as a predominant symptom 2

Post-Treatment Monitoring Considerations

After Pneumatic Dilation

  • Monitor for immediate complications (perforation - chest pain, fever, breathlessness)
  • Long-term monitoring for symptom recurrence (50-60% may need repeat procedures) 1, 2

After Surgical or Endoscopic Myotomy

  • Monitor for reflux symptoms (especially after POEM)
  • Consider proton pump inhibitor therapy and surveillance endoscopy 1, 2

Special Considerations

  • Secondary Achalasia: In patients with possible secondary achalasia (post-COVID, Chagas disease), monitor for systemic symptoms of underlying condition 1, 2
  • Comorbid Conditions: In patients with comorbid eosinophilic esophagitis or autoimmune conditions, monitor for symptoms of these conditions 1, 2

Red Flag Symptoms Requiring Urgent Evaluation

  • Sudden worsening of dysphagia
  • Significant unintentional weight loss
  • Fever with chest pain (possible perforation after treatment)
  • Hematemesis or melena
  • Progressive regurgitation with aspiration symptoms 1

Careful monitoring of these symptoms is essential for early detection of disease progression, treatment failure, or complications, allowing for timely intervention and improved quality of life.
