Area of Science:

  • Pulmonology
  • Gastroenterology

Background:

  • Chronic cough is a common and often debilitating symptom.
  • Identifying the underlying cause is crucial for effective treatment.

Purpose of the Study:

  • To outline an effective diagnostic and therapeutic strategy for chronic cough.
  • To highlight common causes and management approaches.

Main Methods:

  • Thorough patient history and physical examination.
  • Early chest X-ray and lung function tests.
  • Consideration of common causes: postnasal drip, asthma, gastro-oesophageal reflux.

Main Results:

  • Specific therapy yields >90% response rate.
  • Postnasal drip, asthma, and reflux are common causes with normal chest X-rays.
  • Multiple causes occur in 20% of patients.

Conclusions:

  • Investigate thoroughly to determine specific causes of chronic cough.
  • A four-week H2-receptor antagonist trial is indicated for unexplained cough.
  • Non-specific therapy is reserved for undiagnosed or refractory cases.
