The symptoms of tracheal stenosis are similar to those of other conditions so it is important to see your doctor, particularly if you have experienced an injury to your throat. In addition to a feeling of fatigue or malaise, the symptoms of tracheal stenosis typically are:
- Wheezing, coughing or shortness of breath, including difficulty breathing.
- A high-pitched squeal coming from your lungs when you inhale.
- Frequent bouts of pneumonia or upper respiratory infections.
- Asthma that doesn’t respond well to treatment.
- A blue color in the skin or mucous membrane of the mouth or nose.
Causes and Risk Factors
Though rare, tracheal stenosis may be present at birth. More commonly, the condition is the result of an injury or illness, such as
- An external injury to the throat or chest.
- Infections of a viral or bacterial nature, including tuberculosis.
- An autoimmune disorder such as sarcoidosis, papillomatosis, Wegener's granulomatosis and amyloidosis.
- Tumors, benign or malignant, which may press against the trachea, thereby restricting air flow.
- Occasionally, tracheal stenosis may develop after radiation therapy to the neck or chest.
