Many people are bothered by frequent mucus production but do not know the cause of this problem.
Frequent mucus production can be caused by a number of health conditions, including:
Infections
Upper respiratory tract infections such as the flu or cold or severe infections such as bacterial pneumonia are among the causes of excessive mucus.
Allergies
Allergies to dust, air pollution or pollens, and bronchitis can also cause increased mucus production.
Lung disease
Chronic lung diseases such as asthma, chronic bronchitis, cystic fibrosis, interstitial pulmonary disease or lung cancer can also cause excessive mucus.
Other health problems
Other health problems include chronic acid reflux (GERD), heart failure or other environmental factors.
Cold air
Cold air can also cause inflammation in the throat and produce excess mucus.
