A member asked:

Hi, i cough sometimes when i breathe in and lately it has increased and sometimes i cough up phlegm, what could be the cause?

A doctor has provided 1 answer

Nothing specific: A cough is part of the protective mechanisms of the lung. It functions to help bring up debris from the deeper areas of the lung to the point it can be expelled. This can be inhaled irritants like dust/dirt/pollen or mucus triggered by infection/exposure to fumes, etc. . Since it is non-specific sorting it out would require more history of exposure and or more symptoms.
