Is it possible hiatal hernia and intercostal muscle inflammation can cause occasional daytime hypopnea? seeing pulmonary monday, but just curious now.

Yes!: My spouse an asthmatic for 45 years, recently had surgery to repair a large hiatus hernia. Her asthma has cleared! -- with regurgitation of stomach contents there is occas. Aspiration causing pulmonary problems.

Unlikely: This is not a typical problem caused by a hiatal hernia, and it is unclear how to diagnose intercostal muscle inflammation, this even less clear how that would be associated with hypopnea. Hope this helps!
