Existe-t-il un régime alimentaire qui peut améliorer la qualité de vie des personnes atteintes de la Bronchiectasie?

It's a myth dairy causes phlegm. According to medical studies, dairy products do NOT produce mucus. Dairy can thicken secretions but not produce.

I would suggest experimenting with healthy diets to see which type works best for the patient.

My advice to any bronchiectasis patient who is overweight is to shred some pounds. Even healthy lunged people have difficulty breathing if they are heavy.
