Background:

Asthma is a common chronic respiratory disease characterized by variable airflow obstruction.
Upper airway obstruction (UAO) can present with similar symptoms, complicating diagnosis.
Differentiating between asthma and UAO is crucial for appropriate patient management.

Observation:

A case of insidious upper airway obstruction was initially misdiagnosed as asthma.
The patient presented with symptoms suggestive of bronchospasm and airway inflammation.
Clinical presentation and initial investigations created confusion between the two conditions.

Findings:

Specific diagnostic investigations are necessary to distinguish between asthma and UAO.
Key differentiating factors include inspiratory stridor, fixed airflow limitation, and characteristic findings on imaging or endoscopy.
Prompt identification of UAO prevents delayed treatment and potential complications.

Implications:

Highlights the importance of considering UAO in asthma-like presentations.
Emphasizes the need for targeted investigations to differentiate these conditions.
Aims to improve diagnostic accuracy and patient outcomes for respiratory symptoms.
