Which are the symptoms of Tracheobronchomalacia?

Tracheobronchomalacia is a condition characterized by excessive flaccidity of the tracheal and bronchial walls, leading to airway collapse during breathing. The hallmark symptoms include a chronic, "barking" cough, persistent wheezing, and exertional dyspnea (shortness of breath) that often worsens during respiratory infections or physical activity.

What are the primary symptoms of Tracheobronchomalacia?

In patients with Tracheobronchomalacia, the structural support of the airway is weakened, causing the walls to bow inward during exhalation. This mechanical collapse results in several distinct clinical manifestations:

• Chronic "barking" cough: Often resistant to standard asthma treatments.


• Exertional dyspnea: Difficulty catching breath during exercise or daily tasks.


• Audible wheezing: High-pitched sounds caused by turbulent airflow through a narrowed airway.


• Recurrent respiratory infections: Difficulty clearing secretions due to poor airway clearance.


• Post-prandial distress: Symptoms may intensify after eating due to pressure on the trachea.

How does Tracheobronchomalacia affect quality of life?

The severity of Tracheobronchomalacia varies significantly among the 41 members of our DiseaseMaps community. For many, the constant struggle to breathe significantly limits physical endurance and social participation. Symptoms often fluctuate; they may be mild at rest but become debilitating during physical exertion or when the patient is lying flat, which can cause significant sleep fragmentation and daytime fatigue.

When should I seek immediate medical attention?

While Tracheobronchomalacia is a chronic condition, certain "red flag" symptoms require urgent evaluation. You must seek emergency care if you experience cyanosis (bluish tint to the skin/lips), severe respiratory distress, an inability to speak in full sentences, or a sudden, uncontrollable "dying" sensation associated with airway obstruction.

How does the condition progress over time?

The clinical course of Tracheobronchomalacia is not uniform. In some individuals, the airway collapse may remain stable, while in others, repeated infections or chronic inflammation can lead to a gradual worsening of airway obstruction. Monitoring changes in your baseline respiratory function is essential for long-term management.
