Hidden breathing blockage found in severe asthma patients
NCT ID NCT04593394
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how often people with severe asthma also have inducible laryngeal obstruction (ILO), a condition where the voice box closes during exercise, making breathing harder. Researchers tested 116 participants using a special scope while they walked on a treadmill and tracked their symptoms for a year. The goal was to understand how common ILO is and how it changes over time, not to test a new treatment.
