Allergies? Reflux?: A person who has a cough producing mucus (phlegm) should see a doctor. The doctor can evaluate to see if there are allergies, sinusitis, stomach reflux, asthma, bronchitis, or perhaps another problem in the chest. Problems can be more serious if the person is a smoker or has other health problems. Smoking is a major risk factor for several lung diseases, including cancer.
