Phlegm refers to the mucus released by glands located in the lung passages. Some mucus is considered normal and healthy, and it is responsible for keeping certain areas of the body moist. It also protects these areas from harmful bacteria and viruses. However, in many cases, phlegm may be an indication of excessive mucus buildup, and it can cause discomfort. Excessive mucus often occurs when patients have a common cold, flu, allergies, or another upper respiratory illness. It can also develop due to smoking, lung diseases such as pneumonia or lung cancer, and gastroesophageal reflux disease.
