Understand the risks of the Bronchial Thermoplasty procedure

As with any procedure, there are risks, and individual results may vary. The most common side effect of BT is temporary worsening of respiratory-related symptoms. This side effect typically occurs within a day of the procedure and resolves within 7 days on average with standard care. There is a small (3.4% per procedure) risk of these symptoms requiring hospitalization.1
