Excess mucus in the throat is often caused by postnasal dripping of mucus seen in sinus problems, nasal allergies, chronic bronchopulmonary disorders or a headcold. GERD and laryngopharangeal reflux can also cause buildup of phlegm in the throat. An otolaryngologist is best to evaluate and advise you.
