A member asked:

Can constant overbreathing from chronic hyperventilation syndrome cause excess mucus to form on my lungs? i don't know if the mucus is from allergies.

Evaluation: Without exam, chest x-ray and some lab work any answer will be incomplete. See pulmonologist in your area, they will help.

No: The chemistry of your blood will eventually fix hyperventilation. You will either pass out or calm down and then breath less but it will not cause sputum
